Reliable Enclosure Cooling for Commercial Bakeries

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/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.

 

How Pfannenberg Thermal Management & Signaling Solutions Save the Holidays


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.

Pfannenberg – Global Solutions and Support for OEMS


When it comes down to the final decision on whether or not to purchase new equipment for a plant, the decision tends to fall down to three major concerns:

  1. What preventative yearly/monthly/weekly/daily maintenance is required?
  2. Is it able to withstand the environment?
  3. How much time and money will it save?

Enclosure Cooling for Commercial Bakeries – Easy As Pie


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.

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.

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 Exchangersutilize 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!

“We All Scream for Ice Cream” – Pfannenberg’s Thermal Management plays a key role in a favorite summer treat!


From the Farm to the Factory

When the trucks arrive at the factory, the milk and cream are pumped into storage silos and kept cool at 36°F until they are ready to begin the process.

Making the Ice Cream Mixture

The process begins by mixing ingredients and various flavors into a 1000-gallon stainless steel blender.  Heavy cream, liquid sugar cane, and condensed skim milk are the first foundational ingredients. After that, sometimes egg yolks and cocoa powder are incorporated depending on the desired flavoring. A natural stabilizer is mixed in to prevent various ice crystal formation or heat shock.  Blended for a total of about 6-8 minutes, it is then ready to be transferred and strained into a large tank.  This tank will store the mixture until it is ready to begin the pasteurization process.

Pasteurization & the Homogenizer

Pasteurization heats up the mix to kill harmful bacteria. The mixture flows through various plates. Hot water flows on one side of the plate and cold water (cold mix) flows on the other side of the plate. The heat from the hot water is transferred to the ice cream mix, heating this mix up to 180°F.

Right from there, the mixture enters the homogenizer.  Here the mix is exposed to high amounts of pressure so that the fat particles from the cream do not separate from the rest of the mix.  Then the heat from the ice cream mix is transferred to the cold water, cooling the ice cream mix down to 36°F.

The mix is then moved to a tank room.  This room is cooled down to 36°F degrees, where the mix will be stored for 4-8 hours which allows the ingredients to really form.  Next more flavorings are mixed in (such as vanilla, peppermint, purees, and other extracts).  Once the appropriate flavors are added it is then transported into the freezer.  The temperature has to be below freezing, most plants keep it at -40°F.

Freezing & Packaging

To further the process in making hard ice cream, it travels to the packaging area of the factory.  Here the soft serve ice cream is dispensed into various packaging containers and then delivered into the storing freezer before shipment. At this point the temperature of the mixture is around 22°F. For the mixture to reach a colder state it has to enter a spiral freezer where it travels around in a -60°F maintained temperature part of the plant.  When the ice cream leaves the spiral freezer it should be around -10°F. From there the ice cream cartons are stored into various freezing warehouses until they are shipped.


So what role does Pfannenberg play in this desired product?

Automation plays a critical role in the manufacturing of ice cream. Numerous electrical enclosures contain the critical electronics (VFDs and control components) to operate the machinery ranging from mixing to the final packaging. Even though these enclosures are found within a relatively cool environment, the temperature inside the cabinets needs to be maintained. Without proper enclosure cooling these electronics may overheat, bringing operations to a halt. Pfannenberg’s PWS Air to Water Heat Exchangers are ideal for cooling electrical components found in food and beverage processing facilities. The units can utilize existing cooled liquid while saving energy costs vs, traditional compressor based AC cooling units. Our cooling solutions make this cool summer treat possible.

Pfannenberg Products Assist in Making an American Staple Summer Treat


Hot dogs – a staple summer treat that brings back memories of family cookouts and baseball games. It is an American favorite summertime food! Hot dogs go through a series of complex processes that combine the ingredients into their delicious final form and Pfannenberg’s PWS Air to Water Heat Exchangers are perfect to keep things running.

Meat Processing

The first step into creating one of the most loved foods is the preparation of the meat.  The meat is cut into small pieces and is placed into a large mixer.  These mixers have chopping blades to further cut the meat into smaller sizes. Here the raw ingredients and flavorings are added.  All are mixed until the mixture is a smooth paste consistency. Processes like this can require large control panels to operate the system and Pfannenberg’s PWS Air/Water Heat Exchangers are ideal for cooling your electrical components. Pfannenberg’s Air/Water Heat Exchangers utilizes chilled water, that is readily available, and an internal fan to provide cool air to prevent critical electronics from overheating.

Linking

The paste is always going through inspections throughout the entire process. After inspection from the mixer – the mix is moved into a stuffer.  This machine will push the paste into tube casings.  The casings are twisted at measured sections to make equally sized hot dogs. There are various casings – natural or artificial. The shaping of the hot dogs we all know is now complete.

Smoking

After the stuffing and linking, the hot dogs are then moved to a smokehouse to cook under controlled conditions.  Manufacturers can control the temperature and the difference flavors that the smoking has on the hot dog by using difference smoke sources.  Average time it takes in this step is an hour.

Final Processing

Once the smoking is completed, the link casings are removed by an automatic peeler.  During this time, the hot dogs are sprayed with water to help bring down their temperature.  Then the hot dogs are then transported to be packaged. Before going into the final packaging, the hot dogs are inspected to make sure there are no foreign ingredients in the product.

Pfannenberg has experience with inspection and x-ray equipment. Pfannenberg was able to combine a Chiller and PWS Air to Water Heat Exchanger to cool the x-ray tubes as well as the electrical enclosure as one example.

The packaging machines can process thousands of hot dogs in an hour.  They are operating at very fast speeds and require proper thermal management cooling to keep their machines up-and-running. Once packaged, hot dogs are inspected again, freshness dates are added, and they are all boxed up to be transferred to the warehouse for refrigeration until they are shipped. The entire process from start to finish, only takes a few hours.

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


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.

The Technology of Cooling Part 4: Closed Loop Liquid Cooling Solutions

1. Air to Water Heat Exchangers

Pfannenberg Air to Water Heat Exchangers use a supplied water source to remove the heat from the electrical cabinet. The heat from the enclosure is transferred to fluid and the heated fluid is then piped away adding no heat to the ambient environment.  Because there is no heat transfer to the ambient environment, there is no need to de-rate the units performance in high ambient conditions.

 

How do I know if a Air to Water Heat Exchanger is the right product for my application?

  • If there is a chilled water supply readily available at the enclosure.
  • If the environment has extreme conditions like extremely high ambients, extremely dirty or caustic, that make other systems not applicable.

 
Properly sizing a Air to Water Heat Exchanger

To properly size an Air to Water Heat Exchanger you must know the required cooling capacity in Watts, available water temperature and the dimensions of the unit and enclosure.

 

Utilizing performance curves to properly size cooling units:

Pfannenberg utilizes the DIN standard 35/35 °C when rating our cooling units. Many other companies use 50/50 °C, which provides a higher, non-usable value. Customers should use their own application temperatures to determine the proper cooling capacity of the system.

 
Important information when utilizing Air to Water Heat Exchangers for enclosure cooling:

  • The performance of an Air to water Heat Exchanger is directly related to the difference in the water temperature and the air temperature inside the enclosure.
  • To manage condensation, an external condensation evaporator (KVDTX) can be used.
  • The enclosure should be sealed to prevent the inflow of ambient air.
  • Use the door contact switch to impede operation with open doors and consequent excessive accumulation of condensation.
  • Setting the temperature to the lowest setting is not the optimal solution due to the condensation issues. The value we have preset on the cooling unit is a sound compromise between cooling the inside of the enclosure and the accumulation of condensation.
  • Make sure unit is level.

2. Chillers

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.

 

How do I know if a Chiller is the right product for my application?

  • When higher heat loads that exceed traditional enclosure cooling methods need to be managed.
  • When precise temperature control is required as part of the manufacturing process.
  • Large fluctuations in heat load requirements need to be managed.
  • It allows the source of cooling to be located separately from harsh environments.

 

Selecting the correct Pfannenberg Chiller

Choosing the best packaged chiller to meet the demanding requirements of today’s 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. Click on the picture to open the PDF or use this link!

 

Important information when utilizing Chillers:

  • Chillers can be installed indoors if the area around the unit is relatively clean and the air is temperate.
  • Locating the chiller outside can be a good option and can improve the efficiency of the chiller depending on temperature.
  • Extreme temperatures can cause capacity issues or the need for additional options such as a low ambient package.
  • A chiller should be sized as close to the required capacity based on the desired chilled liquid supply temperature and the highest expected ambient temperature.

3. Combined Chillers and Air to Water Heat Exchangers

liquid_cooling_3D.jpg

When a Liquid Cooling Source is not available on site, use the combination of chillers and air/water heat exchangers to simplify the cooling of your processes, machines and controllers as part of a system based solution.

Via a closed pipeline system that uses a highly economical supply of cooled liquid (e.g. water, glycol or oil) as the cooling medium, temperature can be managed within your process and as the cooling medium for the air conditioning of control cabinets. When cooling cabinets with PWS Air/Water Heat Exchangers the thermal management is 100% independent from the ambient temperatures at the installation location.

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


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

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

  1.  First determine the heat load for the whole assembly.
  2. 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).
  3. 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.
  4. 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.
