Solutions to Reduce Maintenance & Repair Costs

 

Electrical Enclosures and Enclosure Air Conditioners

Electrical enclosures and enclosure air conditioners often fall victim to flour damage in the make-up area of commercial bakeries. The “make-up area” is where dough is prepared by combining flour, moisture, and heat. When flour becomes wet due to ambient humidity levels, it forms a paste-like consistency. The build-up of flour and paste within the air conditioner leads to reduced performance and failure. Without proper cooling, the added stress and risk of failure for variable frequency drives andBakery - large mixing bowls enclosure electronics can lead to costly repairs and downtime.

Many commercial bakeries still use air conditioners to cool electronics in the make-up area because they provide convenient closed-loop electronics cooling. But this solution is not sustainable due to high concentrations of particulates in the air, which eventually clog air conditioners such that they fail. However, opening the doors to the enclosure to provide needed cooling ultimately does more damage by compromising the NEMA 4/4X environment.

Electronics must receive proper cooling solutions. This is because they have a narrow “sweet spot” for cooling between 85 degrees and 95 degrees Fahrenheit. Lower temperatures risk condensation which can lead to water forming on electronics, while higher temperatures can cause heat stress failure.

 

A Solution for Commercial Bakeries – Liquid Cooling

Instead of air conditioning, a superior solution for bakeries is liquid cooling, which eradicates heat from enclosures in an efficient and cost-effective capacity. Liquid cooling proves especially well adapted to hot, dirty environments where it removes heat from machines. This makes liquid cooling the ideal solution for the makeup area in commercial bakeries.

Air to Water Heat Exchangers

When one of the fastest growing independent, family-owned baking manufacturers in the U.S. sought to optimize their resources, they turned to Pfannenberg. Drawing upon its decades of experience and expertise, Pfannenberg suggested a liquid cooling solution.

Pfannenberg’s PWS Series Air-to-Water Heat Exchangers now provides this leading bakery with a trouble-free cooling solution for their electrical enclosures in the make-up area. This solution easily operates in dusty environments where moisture and flour fill the air. To cool the bakery’s electrical units, the solution also utilizes glycol or a cool water source that the factory already has available.

In addition to sustainable cooling, the bakery improved the cleanliness of their electrical cabinets with this product. This is because PWS Series Air-to-Water Heat Exchangers have no filters, which means no down time results from changing filters or having them become clogged. The products also improved the efficiency of the cooled air by providing a stable temperature that sustained cool air, unlike previous AC units that would get clogged with airborne particles.

 

PWS Series Air-to-Water Heat Exchangers

By implementing four PWS Series Air-to-Water Heat Exchangers in the make-up area, the bakery overcame problems plaguing their enclosed electronics and achieved energy savings by eliminating the need for compressors and tapping into existing water or glycol lines that run throughout the manufacturing facility. The bakery also reduced maintenance costs by removing the risks of clogging and preventing unwanted repairs.

By partnering with Pfannenberg, this bakery took its business to the next level, and now seeks to implement even more Pfannenberg products to augment its manufacturing process. With products and solutions designed to meet high quality requirements and operate in the harshest conditions, Pfannenberg continues to prove itself a leader in innovative industrial solutions.

Thermal Management Solution for Large Commercial Bakery

/in ,

thermal management solution bakery cooling racks

Supermarkets strive to craft fresh and unique baked goods to bolster their brands. Any downtime in the baking process can turn away customers at the door.

One of the largest commercial bakeries for supermarkets, which supplies 19 US states and parts of Canada, had repeated failures in its electric enclosures’ air conditioners, which were breaking down throughout its plants. To overcome this issue, the bakery sought a reliable thermal management solution that could function effectively in hot and dusty environments.

commercial bakery solution mixing areaThe search for the ideal solution brought the bakery to Pfannenberg, who conducted a plant survey to identify the central problem — many A/C units were undersized for ambient air temperature and heat loads generated for the enclosures. Increased temperature in the electrical cabinet during summer months reduced component life and overheated the enclosure.

A/C units on the electrical cabinets were typically part of the OEM equipment and not sized properly for the plant’s ambient conditions or the enclosures. This motivated the bakery to search for a cost-effective solution that could reduce downtime and cut energy costs.

Pfannenberg quickly saw that the problem could be solved with its PWS Series Air-Water Heat Exchanger. Effective at providing cooling in harsh environments, this product provided the perfect fit for electrical enclosures throughout the bakery’s facilities.Air to Water Heat Exchangers

The cooling mechanism of the PWS Air-Water Heat Exchanger draws hot air from the enclosure into the top of the unit, then passes the air across the unit’s coil. When the heat leaves the coil, it cools the air. The cool air then continues moving out the bottom of the unit.

Because the unit has no refrigeration system, it did not require an external condenser air circuit. Ambient conditions also had no influence on how the air-to-water heat exchanger performs. Moreover, chilled water was already available in the bakery’s manufacturing plant, such that the Pfannenberg Air-Water Heat Exchanger achieved substantial energy savings while requiring little-to-no maintenance. No filters needed to be changed or cleaned.

After implementing the new product, the bakery saw a one-year return on investment (ROI) based on the total cost of ownership (TCO) for the bakery’s previous A/C units. On top of this, the bakery applied for energy rebates from their local utility to offset the investment, given that the payback period was less than 5 years.

Providing a complete, turnkey solution to thermal management, Pfannenberg empowered the leading bakery to slash costs in a sustainable fashion, reducing downtime to ensure the seamless flow of baked goods to its hungry customers.

Enclosure Cooling for Commercial Bakeries? Easy As Pie!

/in , , , ,

In today’s modern lifestyle, frozen foods have played a major role in providing convenience to customers.  Pies – a family fall favorite, often take time that many families do not have. This is the time of the year where kids are back to school, parents are running all over doing drop-offs and pick-ups, rushing to work; taking the time to bake or make a full meal is often difficult.  Large industrial bakeries can manufacture roughly 200,000 frozen pies a day.  There is a high demand in this modern age for this aspect of convenience.

 

The two most important characteristics of creating a great tasting pie are the filling and the crust.  For the filling, fruit is mixed with sugar, cinnamon, honey and other spices (depending on the type of filling) in a large sauce pan. Ingredients are heated and mixed to combine the flavors for the filling.

This process requires automation components such as VFDs in large electrical control panels to operate the system. Heat is a by-product of this process and Pfannenberg’s PWS Air to Water Heat Exchangers are ideal for cooling electrical components.

Pfannenberg’s Air Water Heat Exchangers utilize chilled water, that is readily available, and an internal fan to provide cooled air preventing critical electronics from overheating. These units are particularly adapted for harsh environments like bakeries when there’s flour everywhere.

These pies are then moved to the depositing machine, where the filling is then dropped into the pie sheets.  The lid of crust is then placed on the filled fruit pie.  These lids are mass produced and “forked” or sealed to give that touch as if it was just like our mothers or grandmothers homemade pie. These top crust lids help seal in the filling when the pie is being baked at home.  Once sealed, the pies are moved to a blast freezer for rapid chilling.

Once chilled the pie is then moved to be packed and shipped off to local grocery stores.To make that flakey-buttery crust, shortening, flour, and other ingredients are mixed together in a large industrial mixer.  When the dough is done being mixed, the dough is compressed into equal sized squares and dropped into baking pie sheets.  Here, they move along the process and the dough squares are pressed down on the pie sheets to form the bottom crust layer.

The manufacturing processes of frozen pies are a delicate procedure. Temperature control of the equipment and the product is important to producing a flavorful, flakey, and scrumptious pie crust.

So what will it be?  One slice or the entire pie?  Ice cream or whipped cream? Next time you are enjoying a piece of pie, be sure to appreciate the process it takes to produce such a delicate indulgence!

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!

Reliable Enclosure Cooling for Commercial Bakeries

/in , , , , , , ,

Customer Requirement

Pfannenberg worked with a bakery end user to develop a cooling solution for their control cabinets.  Most of the OEM equipment installed in the bakery called for air conditioners to cool the drives. PLCs and additional electronics. Most times Cooling units can be a convenient and effective method for cooling electronics, except when located in dusty, humid areas within the plant.

These AC units failed regularly and had to be replaced. This was not a sustainable solution as the customer had constant issues with clogging coils and overheating panels.

Once a panel overheated they had to either: not operate the machine, or operate the cabinets with the doors open. This would let all the contaminants that were hurting the AC units into the cabinet, damaging the drives and other components.

The Pfannenberg Solution

To use the chilled Glycol that was already present for other machine processes to provide the cooled liquid source for our PWS Air to Water Heat Exchangers.

The solution included:

  • A reliable cooling solution designed for harsh environments
  • Reduced maintenance.  Once installed the units only have just one moving part, so regular maintenance is not necessary
  • Eliminating equipment failures, means greater uptime
  • Reduced energy costs with the PWS units
  • UL Tested NEMA Type 4/4X – washdown

Customer Benefits

Pfanneneberg’s PWS Series Air To Water Heat Exchanger was the precise solution for the problems our customer experienced. Incorporating Air/Water Heat Exchangers improved performance, reduced maintenance, was energy efficient, and prevented unplanned repairs.
