Spring Cleaning – 3 Steps you Can Take to Prepare your Cooling Units for the Stress of the Summer Heat

/in , , , ,

With hotter temperatures just around the corner we’ve put together this Preventative Maintenance Video to help you prepare your enclosure cooling units for the stress of summer heat.

To avoid any critical component failure, follow the 3 simple steps below to help ensure your enclosure cooling units stay up running all summer. Don’t Wait Until it’s Too Late!

STEP 1: Make Sure your Condenser Coils are Clean

The condenser coils are one of the most important components of your Cooling Unit, they ensure the reliable, cost efficient and long-term operation of your unit. When dirt, dust or debris builds up on your condenser coils, it can have a major effect on the performance of your cooling unit.

STEP 2: Check your Fan Motors and Inside/Outside Electrical Components

In order to prevent failure, the cooling unit’s fan motor and fan blades need to be inspected to determine wear and damage.  All the electrical components in the control box also need to be checked to make sure all connections aren’t damaged or loose.

STEP 3: Set your Unit to the Recommended Proper Temperature

Pfannenberg sets the dip-switches on the control board to 95°F/35°C in the factory, and recommends that the dip switch settings are not altered.

*Having the dip-switch temperature set to a lower point can cause damage not only to the cooling unit, but to the composure as well.  Changing the set point can cause the cooling unit to run excessively, possibly causing damage to the compressor and other components.  It can also cause the enclosure to produce condensate, possibly damaging electrical components inside the cabinet.

Pfannenberg to Showcase New PKS 3000 VFD Control Panel Cooling Technology at EASA 2019

/in , , , ,

Visit booth #561 to see more efficient, high-performing air to air heat exchanger

Pfannenberg will highlight their advanced Pfannenberg Kinetic System™ Series Air to Air Heat Exchangers for removing heat from VFD control panels at booth 561 at the 2019 EASA Convention in Las Vegas, NV, held from June 30th to July 2nd.

Additionally, Pfannenberg will be presenting their new PKS system and how this solution could improve the reliability of VFDs while reducing energy consumption and maintenance compared to other thermal management products on Monday July 1st at 2:30 PM at the New Product Theater.

Perfect Solution for VFD control panels Cooling

Pfannenberg’s PKS Series Air to Air Heat Exchangers use a revolutionary next generation cooling technology (Pfannenberg Kinetic System™) to remove heat from VFD control panels while preventing ingress of contaminants into the enclosures. These environmental parameters within the VFD cabinet, temperature and dust, could determine the service life of the VFD.

A VFD running at 18°F above its recommended ambient temperature could lose up to 50% of its expected service life. Industrial air conditioners are typically the go-to solution for cooling VFDs and other critical electronics housed in sealed enclosures. However, a cooler ambient environment could also be used to help control the temperature within the cabinet. Lightweight and easy to install, the PKS technology takes advantage of a cooler ambient environment to remove heat from within the enclosures while sealing against gas, humidity, and dust. The patented technology, unlike industrial air conditioners, does not utilize a refrigerant cycle that has a high energy consuming compressor, making it more efficient to operate from a uptime reliability and energy savings standpoint.

PKS Series Air to Air Heat Exchangers

PKS Series Air to Air Heat Exchangers are designed for indoor (NEMA Type12), outdoor (NEMA Type 3R), and washdown (NEMA Type 4X) applications that require protection from harsh ambient conditions.

They are also ideal for keeping water and dust from sensors and drives on outdoor systems, and protecting against corrosion and contamination in the food and beverage industry.

This is a perfect solution for those looking to reduce the energy, maintenance and footprint associated with traditional enclosure cooling units. This new technology offers considerable saving compared to a traditional AC unit.

In addition, with only two mechanical elements, PKS Series Air to Air Heat Exchangers require less maintenance and ensure greater uptime!

Why Pfannenberg’s Cooling Units Do Not Need A Filter

/in , ,

Pfannenberg’s ‘service-friendly’ DTS cooling units provide effective cooling for tough industrial or outdoor applications. Their closed-loop designs ensure that ambient air, dust, and humidity are not passed to the interior of the enclosure, thereby keeping sensitive and critical electronics safe from contamination and in prime operating condition.

Pfannenberg’s DTS Cooling Units filter-less design reduces the amount of required maintenance needed for operation in dirty environments. Indeed, if a dirty filter is not cleaned or replaced, it can become clogged which severely limits its efficiency and result in poor performance.

Filter-Less Design

  • High Airflow Backward Curve Impeller Fan
    Provides high airflow in a long lasting, single bearing design. Higher airflow pushes dirt through wider fin spacing allowing for less clogging which avoids system failure.
  • Large Fin Spacing
    Large condenser fin spacing allow for longer maintenance periods, even without an additional Nano coating. They are less susceptible to clogging from dirt buildup which can cause the unit to work harder and hamper efficiency.
  • Corrosion Protection
    The DTS Outdoor and wash-down units have a special coating on pipes and coils on the ambient side of the unit to provide maximum protection from saltwater, sour gas, and other corrosive substances.
  • Self-Protected Electronics
    Our unit is uniquely designed to protect itself in NEMA 3R, 4, and 4X environments. An example of this is the location of our control electronics within our dry, cool interior circuit.

 

How to Avoid System Failure

As with any unit located in a dirty environment, the components around the external air circuit require periodic cleaning. To avoid any critical component failure, follow the 3 simple steps below to help ensure your enclosure cooling units stay up running:

  • STEP 1: Make Sure your Condenser Coils are Clean
    When dirt, dust or debris builds up on your condenser coils, it can have a major effect on the performance of your cooling unit.
  • STEP 2: Check your Fan Motors and Inside/Outside Electrical Components
    The fan motor and fan blades need to be inspected to determine wear and damage.  Also make sure electrical components aren’t damaged or loose.
  • STEP 3: Set your Unit to the Recommended Proper Temperature
    Pfannenberg recommends the dip-switches on the control board to 95°F/35°C in the factory.

All maintenance should be performed by qualified personnel, following all safety procedures. To help you perform your preventative maintenance, Pfannenberg realized a simple video following the 3 above steps: Watch the Full Video Now!

Stronger than the elements – Pfannenberg’s DTS 3000 series Outdoor Thermal Management Devices

/in , ,

When conditions are harsh you can count on Pfannenberg’s DTS 3000 series cooling units to protect your electronics in extreme heat, cold, wet or dusty environments.

System integrators and planners often struggle with the thermal management of electrical enclosures in outdoor applications: extreme temperatures, moisture and dust are particularly challenging with some applications exposed to the elements 24/7. Pfannenberg, the world leader in the Thermal Management of electrical enclosures, has designed a range of cooling units which represent a solution to providing protection in these harsh environments.

DTS cooling Units

Pfannenberg’s DTS 3000 series Cooling Units, cooling capacity from 300W to 6.3kW, are suitable for use in demanding outdoor locations. These products are categorized in protection classes NEMA Type 4/4X and IP 66. Pfannenberg also offers heaters, thermostats and hygrostats to prevent the formation of damaging condensation.

Typically, these cooling units are used for applications in demanding environments such as deserts or extreme cold, in buildings, traffic and energy technology, in sewage and water treatment plants and in metal production/processing. They are also found in other harsh manufacturing systems for cement and building materials, the timber industry, wind,  water power generation and photo voltaic applications. Users even rely on these versatile devices in mobile equipment. Pfannenberg’s DTS 3000 series cooling units are therefore making a contribution to the energy transition.

“Pfannenberg is focusing on the growing global market for demanding outdoor cooling systems. We have have a name in the thermal management of electrical enclosures for indoor applications and with an extremely broad portfolio of devices which also meet the NEMA standard, we can cover almost every application scenario,” says Jörg Achenbach, Regional Product Manager, Thermal Management for Pfannenberg EMEA.

“Outdoor conditions are often extreme: wildly fluctuating weather situations like rain, frost and heat all present problems as do a high concentration of particles in the air, hail, snowstorms, aggressive vapors and cleaning with powerful water jets and cleaning materials. Pfannenberg offers solutions in the DTS 3000 series for all these environmental conditions, with models that can operate in temperatures ranging from -40 °F to maximum 140 °F”, explains Achenbach.

 

Robust and reliable

Pfannenberg’s DTS 3000 series offer powder-coated NEMA 3R/4 but also Type 4/4X 304 Stainless Steel units for use under the toughest conditions. A hermetically sealed cooling circuit not only ensures prevention of leaks, but also makes topping up with coolant unnecessary. Systems to protect against thermal overload, corrosion and excess pressure ensure that these outdoor cooling units have a longer operational life.

 

Dust and moisture remain outside

To prevent ingress of foreign bodies, dust or water, Pfannenberg’s outdoor cooling units meet the requirements of IP 56 and N3R protection classes as standard. Also, the DTS 3000 outdoor units condensers fins are 3 mm apart which makes them less likely to trap dust. One of the advantages of this design is that the units are almost completely maintenance free – even with very high concentration of particulate in the air.

 

Low Ambient (LA) equipment package for low temperatures

The Low Ambient (LA) anti-frost package has an integrated enclosure heater and an intelligent fan control system to ensure that the machinery operates without interruption and provides excellent protection from condensation at temperatures as low as -40 °F. The extracted moisture evaporates in the device before it can cause damaging short circuits in the enclosure. The package also includes a safety overflow and a thermostat which can be installed in the enclosure. The LA package is available with cooling capacities from 700W to more than 5kW for the DTS 3000 cooling units. The integrated electrical enclosure heater, which is very easy to install, is offered in versions up to 3kW.

 

High Temperature (HT) package for extreme heat

The High Temperature (HT) package has a temperature-stable compressor and a large condenser for reliable protection of enclosure components at exceptionally high temperatures up to 140 °F. The HT package is available for compact 700W cooling devices and also for large, powerful solutions up to 3200W.

 

Even better equipped

Compact fan heater with thermostat

As a useful addition to the outdoor cooling devices, Pfannenberg offers 10W – 1200W supplementary heaters, thermostats and hygrostats for monitoring relative humidity levels. Depending on the application, this additional equipment offers further protection from condensation and corrosion and helps to optimize the energy/cost ratio. 

As a system: cooling units, heaters, thermostats and hygrostats will ensure that the environment within the enclosure is ideal for performance and service life of the critical electronics.

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.

Case study: Pfannenberg Cooling Units to meet Wood Manufacturing needs

/in , ,

An end user turned to Pfannenberg for assistance with managing their enclosure temperatures in a particularly harsh environment. The company produces high-quality construction and installation materials from wood fiber.

Customer Requirement

The customer current system was facing system failures and downtime due to severe soiling from wood dust and rust particles from diesel-powered fork lift trucks and heavy equipment. The current thermal management solution used conventional point-of-entry filters and top-mounted filterfans. The current cabinet system had to be completely changed as it needed to be reliable despite severe air contamination from wood dust and exhaust gas, plus provide energy savings and service friendliness.

The Pfannenberg Solution

As a first step, all the switch cabinets were wet cleaned, both inside and outside.  To rule out any repeat soiling, the top-mounted fan combination was replaced by partially recessed cooling units: DTI 6301 Model.

Special features of the cooling units are:

  • Uniquely high energy-efficiency rating (EER)
  • Significant energy savings/operating costs reduction
  • Condenser with wide fin spacing for highly effective protection against contaminated ambient air
  • Large distance between intake and exhaust vents (to eliminate hot spots)
  • Perfect ease of servicing
  • New service interface for easy retrieval of parameter settings/history (Pfannenberg Plant software necessary)
  • Optional filter can be retrofitted in a few seconds
  • Energy-savings mode in the Multi Controller integrated as standard

Customer Benefits

Use of the new DTI 6301 cooling units led to reliable system operation and to the highest possible amount of machine up time. The environmental and cost balance sheets demonstrated considerable reductions with regards to energy costs and CO2 emissions, as well as reduced service requirements and repair times.

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.
