Selecting a Packaged Standalone Chiller

/in , ,

By: Adam Wells (Solutions Engineer, Pfannenberg USA, Inc.)

 

When considering a liquid chiller system, precision and accuracy are critical for the temperature control of the application. Innovative cooling equipment is essential to regulate temperatures to ensure effective control. Find out how to select the best liquid chiller system for a given application by following the very important steps laid out here.

Calculate system size

Correct selection and sizing of the liquid chiller system for a given application can make a significant difference in reducing startup waste, achieving higher quality applications, increasing product output, and improving profitability. Calculating the size of the liquid chiller system using correct application details is critical to achieving accurate process cooling with a liquid chiller. Further, the size or capacity of a liquid chiller system must be designed to accommodate the varying workloads and ambient conditions that affect the system.

Performing sizing calculations

The three main factors for sizing are:

  • Incoming water temperature (°F) (also known as processed water temperature),
  • Required chilled water temperature (°F) (also known as the setpoint of the chiller), and
  • Flow rate (measured in gallons per minute, or GPM).

Understanding the liquid medium

Cooling processes can be handled with any one of three different mediums: water, water/glycol, or heat transfer oil. Which fluid type selected depends on the temperature the system must achieve, cooling loads, and process requirements like flow capabilities, cycle times, material, etc. In cases where pure water is not a usable medium for the application, glycol and heat transfer oil can be utilized partially to create a water-based emulsion. Cooling capacity correction factors must be made if glycol or heat transfer oil will be utilized.

Determine appropriate controls

Liquid cooling demands accuracy and reliability for temperature stabilization, while operators need easy-to-use and highly visible controls and indicating lights. Pfannenberg chillers offer microprocessor-based controls that provide control performance, visibility to operators, and are configurable to meet specific application needs. A variety of control features including flow/pressure alarms, ambient temperature alarms and remote communication options are available to ensure optimal and desired results.

Prolong the life of your liquid chiller system

Preventive maintenance procedures should regularly be performed to keep the liquid chiller system clean and well-maintained. Performing weekly, monthly, and quarterly checks will extend the life of a chiller system. Refer to the procedures provided in the manufacturer’s instruction manual. By following some basic guidelines before, during and after installation, users can extend chiller lifespan, avoid mechanical/electrical problems, and ensure that a liquid chiller system will provide a high level of efficiency and reliability throughout its lifetime.

Liquid Cooling Solutions, the Best Choice for Complete Plant-wide Machine Cooling

/in , , , , ,

When it comes to Thermal Management, cooling each machinery or electrical cabinet separately is usually the solution chosen by most of the industries. However, this leave a valuable optimization potential untapped.

Maximum efficiency cooling for a whole system can be achieved with a cooling system solution consisting of air to water heat exchangers and water-based chillers. These ‘Liquid Solutions’ cool the complete assembly and offer significant benefits compared to traditional approaches such as cooling with ambient air.

How does it work?

A closed loop cooling or semi open system is used to provide cooling to the entire plant assembly. These might be electrical enclosures, processes or individual machine parts such as spindles, motors or hydraulic equipment.

Liquid Cooling Solutions

In a closed-loop system, electrical enclosures or assemblies are cooled with cold water at a specified inlet temperature which is pumped through a pipe system. Flowing through the electrical enclosures or assemblies, the water is warmer when it returns to the chiller. This creates a temperature delta which the chiller equalizes by cooling the water from the outlet temperature down to the inlet temperature.

The process chiller system feeds cold water into the application inside the factory hall or outdoors and the constant flow temperature significantly improves machine availability and machining accuracy. There is no other cooling media being as efficient as water cooling.

The best Liquid Cooling Solution: Combined Chillers and Air to Water Heat Exchangers

The combination of application-specific process chillers with air to water heat exchangers is particularly suitable for applications in which heat must not be dissipated in the immediate environment, where the ambient air is too aggressive to allow the use of traditional enclosure cooling units, where high-level protection is required (up to IP 65) or where the cooling devices must be maintenance-free.

The air to water heat exchanges are all cut-out-compatible and fit in the housing of all available electrical enclosures. This means that machine and plant manufacturers, end users and distributors benefit from higher flexibility, and save costs on warehousing and servicing.

The advantage of an intelligent system solution with application-specific chillers and air to water heat exchangers is that the dissipated heat can be moved directly from the factory shop floor via air channels or an outside chiller system. It also offers very high reliability and problem-free operation as all the components of the system are chosen to work together perfectly. Low maintenance, cut-out-compatibility and energy efficiency optimize energy consumption and keep operating costs to a minimum. The integrated concept and numerous options allow the system to be adapted to almost any application, even with changing conditions.

Application-specific configuration

EB 2.0 Group

Pfannenberg’s experts work with their customers to develop application-specific chiller systems. To achieve exactly the right configuration, it is essential to:

  • First determine the heat load for the whole assembly.
  • The second step is to specify the type of cooling medium (ideally water), the target temperature and the flow quantity which the system must deliver in the actual application. This process should take into account how the heat is transmitted to the cooling medium and the type of refrigerant necessary to operate the refrigerant circuit. The type of cooling medium and which chiller model is used depends on whether usable process water is available at the factory and if so, whether it is warm or cold (see overview of device variants).
  • An analysis of the environmental conditions prevailing where the chiller system is to be installed is also carried out. For example, there might be high temperatures and contaminated air indoors, while outdoors the temperature might fluctuate widely. Both of these factors can have an impact on the configuration of the chiller system, making accessories such as filter fans or crankcase heating necessary. Taking the temperature of the cooling medium at the inlet and the highest likely ambient temperature as a basis, Pfannenberg determines the best chiller model with the correct characteristic curves for the job.
  • The final stage in the application-specific configuration is to think about whether the selected standard version meets the other requirements of the application, such as performance data, control and regulation options, available space, certifications and color. It is then decided whether standard options are necessary or helpful and if so, which. With numerous available options available, the EB chillers meet the requirements of practically any application in industrial environments.

Pfannenberg offers installation-ready chiller systems with performance specifications ranging from 1 to 160 kW. The modular concept of the EB series allows users to select from up to 30 standard options. These include hydraulic bypass/relief valves, flow monitors, tank level monitors, air filters, air filter monitors, check valves, solenoid valves, single alarm display and UL certification. Special solutions are also available. Click here to determine the correct chiller for your application!

With products that include filterfans, heaters, industrial air conditioners, air to water heat exchangers, packaged chillers, and signaling devices, Pfannenberg offers a full range of thermal management solutions for all types of industries.

Liquid Cooling For Induction Heating Processes

/in , ,

Using Chillers to Ensure the Maximum Cooling Capacity in the Smallest Possible Footprint

Traditional metal working practices are time consuming and inefficient. Heating equipment takes a lot of time and therefore also uses a lot of energy. The removal of heat is also necessary, however, in order to maintain structural rigidness as well as to solidify material in the welding process. Additionally, equipment designs need to ensure it is serviceable. Equipment requires frequent physical contact for maintenance. Safety is also a huge concern with traditional welding or heating processes.

Using Chillers in Induction Welding Processes

Convection alone cannot adequately maintain an acceptable operational air temperature when the ambient air temperature is very high. Therefore, an air-cooled liquid chiller is ideal for removing concentrated heat from process equipment. Induction solves many of the stated problems because it generates heat from within the object instead of an external heat source, saving energy and making it safer to use. Automated induction longitudinal welding is a reliable, high-throughput process.

Factors to be considered when choosing a system for cooling an induction process include cost, space availability, existing utilities, energy and water usage, equipment location, potential for freezing, reliability, and maintenance.

A smart controller in the cooling system will set the minimum and maximum water temperature with an alarm. Plus, a flow switch will trigger an alarm if the flow is too low, protecting equipment from being cooled. In addition, it will have a non-ferrous tank and piping to reduce corrosion and a thick powder coating on the stand-alone chiller, and reliable, easy-to-read fluid indication level readout.

Pfannenberg Packaged Chillers: Closing the loop for Industrial Fluid Cooling Applications

By using the proper temperature setting points, operators improve performance and increase the lifetime of devices. Highly efficient cooling technologies generate cost savings and preserve electrical equipment. Pfannenberg Inc. specializes in just this type of technology. Their air-cooled liquid chiller is ideal for removal of concentrated heat from your process equipment. Operators want to select chillers that have a small footprint for equivalent capacity which is offered in Pfannenberg Inc.’s product lines as well.

Pfannenberg’s Chillers Keep Chocolate Tasting Great

Pfannenberg’s Chillers Keep Chocolate Tasting Great

Chocolate plays a major role in many of our holidays as Valentine’s Day or Easter! Whether it’s a box of chocolates or Easter eggs filled with various sweets – there is an extensive process that goes into making these enjoyable treats!

The manufacturing process of chocolate is a delicate procedure. Temperature control of the equipment and the product is important to producing a flavorful and scrumptious chocolate. All processes related to making chocolates are temperature regulated.

A major aspect of chocolate manufacturing is the conching step. Pfannenbergs’ packaged chillers are an ideal solution for the temperature regulation in this process.  Conching is the step in which the chocolate receives its flavor and smooth characteristics! At this stage, the addition of other ingredients is introduced as metal mixers/rollers mix the ingredients together.  This step generates its own heat, which is integral to keep the flavor and the proper consistency of the liquid state.  This chocolate has to be kept at average of 175°F throughout the process (temperature will vary depending on the type of chocolate).  The length of this process will vary depending on the flavor of chocolate.  Typically the average time spent conching is between 4-6 hours; gourmet chocolate brands will spend 30+ hours at this stage.

Following conching, the next step in the process is tempering.Tempering gives chocolate a distinctive shine and color; adding additional flavor.  It is crucial to have strict temperature control.  For tempering, a cooling tunnel is used to take the ambient air; cooling the air to approximately 50°F.  The air then needs to be heated to ambient air temperature.  Pfannenberg’s process chillers have been used successfully in the production of candy and chocolate.  At this stage it is crucial once again for strict temperature control.  If the temperature of chocolate begins to harden and then is heated to become a liquid state – the chocolate is ruined. For chocolate to receive its distinct flavor, look, and texture – the temperature of the chocolate and the air it is produced in is critical.

Next time you eat a piece of chocolate, be sure to appreciate the process it takes to produce such a sweet indulgence!

Pfannenberg’s Custom Chillers Deliver Liquid Cooling for Chemical Synthesis Reactor

/in , , , ,

Pfannenberg fits chiller into confined space within a packaged Ferrator® targeted for water and wastewater treatment in third world countries.

In their quest to develop an affordable Ferrate synthesis system, Ferrate Treatment Technologies, LLC of Orlando turned to Pfannenberg for help with developing a liquid cooling solution for a small, cabinet based system. While already using Pfannenberg chillers for larger, trailer-based Ferrate synthesis systems, standard packaged chillers were capable of integrating seamlessly within the concept of the self-contained cabinet-based Ferrator system.

The “Packaged Ferrator®”  overcomes the obstacles and high cost of using Ferrate, a highly potent oxidizing disinfectant for water and wastewater treatment. The portable Ferrate sythesis system is a game changer for delivering effective treatment for remote locations in underdeveloped nations.

The Treatment or “Cleansing” of Water Takes on Two Primary Requirements:

  • Eliminating contamination within acquired water prior to using or drinking (potable water)
  • Eliminating contamination within used water prior to its release back to the environment (waste water).

For both requirements, an element of cleansing involves disinfection which can be accomplished by several methods intended to kill, remove, or oxidize the contamination. Techniques include mechanical separation such as filtering and reverse osmosis; exposure to ultraviolet light and radiation; and the addition of chemicals such as chlorine or ozone, and now Ferrate. Each technique has its own advantages, disadvantages, effective cost ratio, and ability to scale up in order to treat the affected volume of water.

Oxidation is a process which causes chemical decomposition as well as breakdown of both organic and non-organic substances and is vital for the removal of contamination from water. As a chemical additive, Ferrate possesses extraordinary oxidation capabilities, however, it has historically been quite expensive to manufacture, which has limited its use primarily to laboratory research applications.

Luke Daly, CEO of Ferrate Treatment Technologies, LLC with the packaged Ferrator system

Attempts to produce economical and commercially viable quantities of Ferrate had seen limited success until Ferrate Treatment Technologies, LLC of Orlando (FTT) changed the game by creating a streamlined synthesis process and point-of-use production device. By eliminating storage, handling, and transportation costs associated with a pre-packaged product, FTT has cut Ferrate deployment costs by more than 85%.

The breakthrough device is called a Ferrator, initially available as a trailer or skid mounted system with various capacities targeted for water treatment applications in rural areas. The Ferrator is suitable for a variety of applications including municipal wastewater, industrial wastewater, drinking water, ship ballast water, and environmental water restoration.

Ferrate is highly effective for oxidation, disinfection, coagulation, de-watering, and deodorizing. Ferrate treatment removes phosphates and heavy metals; kills spores, bacteria, viruses and protozoa; removes colors and odors; and its by products are nontoxic.

Composition of the Ferrator

The Ferrator synthesizes Ferrate on-site from three raw ingredients: iron, bleach, and caustic, which are pumped to a homogenizer and reaction chamber. The final product is a liquid which is stored in a tank. Both the reaction and storage areas require cooling, which is provided by Pfannenberg chillers.

When FTT encountered problems with units from another manufacturer they contacted Pfannenberg to provide EB 150 chillers for skid-based systems.

Due to their successful experience with Pfannenberg chillers for system based electrical enclosure cooling, FTT turned to Pfannenberg once again for assistance with a project that required a chiller to fit in a smaller scale Ferrator system into an enclosure. Initially, a CC 6301 packaged chiller was used successfully; however, new design criteria required further miniaturization and this standard packaged chiller would no longer fit. The Pfannenberg engineering team went to work on designing, building, and delivering and open frame unit based on the CC 6301 that could fit within the confines of the small Ferrator enclosure.

” Without Pfannenberg’s cooperation, full support and timely expertise, FTT could never have achieved this historic build for a major philanthropic foundation that is committed to improving the lives of impoverished people in developing countries.” -Luke Daly, CEO (Ferrate Treatment Technologies, LLC)

The small scale Ferrator is targeted for use in third world areas for the treatment of human wastewater and drinking water. Here, the efficiency of the self-contained system will permit water purification in remote areas in which there are no sewer systems, water distribution systems, or central water treatment facilities. The small size of the Ferrator permits it to be readily transported to such remote areas and even be used as a portable device for use at multiple locations. The goal is not only to reduce the adverse effects of discharging untreated wastewater to the environment, but also improve human health by reducing contamination in water available for drinking.

How Pfannenberg Thermal Management & Signaling Solutions Save the Holidays

/in , , , , , ,

Pfannenberg products ensure that manufacturing operations are up and running – especially during the holidays when many manufacturing lines are always online. Read below on just a few example applications on how Pfannenberg supports these product lines and keeps them running.

Candy Canes:

The go-to holiday candy.  As a child, they are passed out and enjoyed by many, and as adults they are necessary for almost any holiday decoration.  This peppermint candy involves very delicate care when being processed.  There are many differences in temperature to heat up or cool down – just enough that it maintains flavor and will not ruin the product quality.  All throughout the manufacturing process of candy canes, temperatures are critical.  At certain stages, the temperature needs to be increased to help form the canes, then at other parts it needs to be cooled so that it can be mixed to perfect flavor and coloring.

The sugar kneading machine is very large and very powerful.  Right after the sugary mixture is heated up and completed its first round of mixing, it is dumped onto a liquid cooling table, where the candy has its flavoring added and mixed. The amber liquid when being first mixed is heated up to around 300°F.  Once being transferred to the kneading machine, this large machine will mix in the flavoring by pushing and folding the candy – slowly cooling the product from its hot temperature. Pfannenberg’s CC Chillers can play a key role in supplying the cool liquid to the table which kneads the candy.  If the table is left uncooled or heated, it will change the look, consistency, and taste of the final product.  Not only is it crucial to have Pfannenberg Compact Chillers to cool the table, it is also import to utilize Pfannenberg’s PWS Air to Water Heat Exchangers to cool the electrical panels controlling the entire process.

Wrapping Paper:

The wrapping of gifts dates back to the ancient Chinese, but here in the US  it hit its popularity in 1917 when Joyce Clyde Hall and Rollie Hall (founders of Hallmark) decided to modernize it. Wrapping paper is a staple item.  When it comes to holidays and special occasions, there are many steps that go into the manufacturing of wrapping paper.

Artists have to create such artwork which is then etched onto copper cylinders that are bathed in a liquid bath of chromium, which galvanizes the copper to protect it from wear and tear.  From here these rolls each have a various piece of the final wrapping paper artwork.  Each color has its own roller. The paper will go through a series of various printers where it encounters the artwork on the copper rolls for the different colors.  These metal rolls need to be highly controlled with temperature.  Too hot or cold could cause the paper to stick to these rolls and cause a paper jam which leads to loss revenue and downtime. As part of a complete solution  Pfannenberg’s CC Series Chillers help to control the temperature to the print rollers and Pfannenberg’s Air to Water Heat Exchangers provide proper cooling for the control equipment operating these large machines. To complelent our full product line,  Pfannenberg’s Signaling products are needed at every stage of the manufacturing process to alert employees of a problem. Pfannenberg’s Signaling Solutions help the employees to be able to hear and see exactly where the problem is occurring (which machine) and what problem is occurring (what action is need).

Wrapping paper leads to the excitement and mystery of the gift. Without the proper cooling and operation of the equipment that are used to produce the paper, it would be difficult to wrap the gifts.  Pfannenberg aids in the manufacturing process of wrapping paper.

Champagne:

The holiday season concludes with celebrating New Years.  New Years is a time to reflect on the past and perhaps try new things in the upcoming year. Celebrations are had with friends old and new, and champagne is typically the drink of choice. One crucial aspect in champagne manufacturing is the inspection and bottling stages of the process. The champagne bottle undergoes many cleanings and inspections prior, during, and after bottling.  Each stage will monitor and check various aspects.  The final inspection step will make sure that the champagne bottle is not cracked or damaged and to check the champagne to make sure that there are not fragments of cork or metal casing. A bright light will shine through the bottles where a machine will scan and take pictures for an employee to monitor/double check that the inspections are all being passed.

Pfannenberg has proven experience in working directly with food and beverage inspection OEMs to provide complete engineering solutions for the cooling of x-ray tubes and the internal cavity of their inspection machines. The Pfannenberg team has come up with a complete solution to utilize a CC Chiller in conjunction with a small PWS Air to Water Heat Exchanger to cool the x-ray tubes and internal cavity.  By combining products and eliminating a compressor based air conditioning unit, the Pfannenberg liquid cooling solution requires less maintenance and is far more cost effective by eliminating dependencies on different competing products and eliminating downtime.

Understanding the Different Types of Liquids Used in Chillers for Cooling Processes

/in , ,

With manufacturing space at minimum, machine packages have become smaller and liquid cooling has emerged as the most efficient and economical means of removing process heat. Chillers often are the only method of providing sustainable efficiency & reliability performances in “hostile” environments.

A chiller uses a refrigeration cycle to remove the collected heat from a circulating liquid. As the liquid moves through a system of tubes and pipes, it absorbs the heat generated by equipment and processes. This generated heat is then transferred by the liquid back to the chiller where it is dissipated. Fluid is cooled and sent back into the system.

>> Click here to learn more about Closed Loop Liquid Cooling Solutions.

But even if you determined that Liquid Cooling is the right solution for your environment, how do you know which heat transfer fluid you should use?

Liquids Used to Cool Your Processes

Pfannenberg process chillers offer different types of liquids to cool your processes as Water/Glycol mix, Water, and Specific Oils. Pfannenberg always recommend to use the water/glycol mixture as it’s the best way to “Protect Man, Machine and the Environment”.

1/ Glycol-Water Mixture

It is recommended to use a Water-Glycol
mix when freeze protection is needed, for example if the chiller is placed outdoors.

Ethylene & Propylene Glycol coolants, with proper corrosion inhibitors are available with Pfannenberg’s Packaged Chillers – both full strength and pre-mixed.

We typically recommend the use of Propylene rather than Ethylene Glycol, even though Propylene has less heat transfer capability, as it is more environmentally friendly and much safer to use.

Using Glycol for indoor applications is also recommended as it deters scale and corrosion in the system and provide some lubrication to the chiller pump while protecting metals. Outdoor applications need more Glycol depending on the maximum low ambient the chiller may see. The addition of Glycol does bring capacity of the chiller down slightly.

The Glycol to Water ratio is different depending on the customer’s coolant temperature needs as well as ambient temperatures being indoor or outdoor applications.

2/ Water

Depending on your installation, water cooling can be a good alternative as it is an economical and energy efficient solution. Water can be used from a local source (city water), but it is recommended to make sure that the water used is not high in mineral content which can cause corrosion or clog fluid channels. To avoid damaging the components, filtration is always encouraged.

 

Other types of acceptable water are: Reverse Osmosis Water (RO) and Dionized Water (DI)

  • RO Water is a purified water where 90-99% of most contaminants are removed but not all ionically disolved substances.
  • DI Water is water that is passed through a DI reaction chamber and has all its ions removed so all the impurities, salts or minerals that can cause corrosion are extracted.

Deionized water can sometimes be requested by customers, but it can still be damaging to certain materials and cause corrosion due to its high purity level. Indeed, due to the lack of ions, the water wants to attract ions from everything it touches. DI systems therefore require acid and caustic for regenerations and a neutralization system – which uses harsh chemicals – for the wastewater.

If highly pure water is not mandatory, RO water is a better option as the filtering process is not as defined as DI water.

In all cases, it is always recommended to contact a water treatment specialist for supervising or performing the installation and operation of water purification equipment.

3/ Oil

Cooling with oil is dedicated to very specific applications in which the process liquid is an oil or an emulsion with a high viscosity. Pfannenberg’s EB Chillers allow the maximum cooling capacity in the smallest possible footprint.

These chillers are designed to handle the oil entering the evaporator at higher temperatures than in typical processes. This solution is mainly used for recirculated cooling of machinery, hydraulics, automation components, etc.

 

 

Properly selected equipment is key to cooling efficiency

Whatever your industry, selecting the best packaged chillers to meet the demanding requirements of your industrial applications can be complicated. For that reason, Pfannenberg designed a 6 step guide to help you select the best chiller depending on your environment, process and type of application.

Chillers for X-Ray Machines – A Food & Beverage Success Story

/in , , ,

With the next round of Food Safety Modernization Act (FSMA) updated regulations taking into effect September, food processing companies are scurrying to make sure their facilities are up to code. The newest set of updates will support efforts into the quick responses to food/beverage related emergencies (contamination, expired products, recalls, and foreign materials). The new amendments also require that the FDA inspect the food production facility every two years to make sure that the facility and products adhere to all regulations.

A simple first step into maintaining food processing safety is x-ray/inspection equipment for product safety and making sure the machines operate properly.  In making sure these machines operate properly, one has to make sure that they have the proper thermal management equipment; something in which Pfannenberg has extensive experience in.

Success Story

Pfannenberg worked directly with a food and beverage inspection OEM to provide complete engineering solutions for the cooling of x-ray tubes and the internal cavity of their inspection machines. These machines would end up in various food & beverage and pharmaceutical end use facilities.  Before meeting with Pfannenberg our customer used several different competing thermal management products; conventional cabinet air conditioners to cool the machine cavity, two small internal fans to move the air around and a small chiller. It was costly, cumbersome while leading to additional maintenance costs and condensate issues.

The Pfanneberg team came up with a solution to utilize a CC Chiller in conjunction with a small PWS Air to Water Heat Exchanger to cool the x-ray tubes and internal cavity.  By combining products and eliminating an air conditioning unit, the Pfannenberg option required less maintenance and was more cost effective eliminating dependencies on different competing products.
