Sealed enclosure cooling solutions ideal for extreme indoor or outdoor environments

Lancaster, NY – Pfannenberg, Inc., a leading global manufacturer of thermal management and signaling technologies, highlights its high-efficiency liquid cooling solutions for industrial electronics. Pfannenberg EB 2.0 Large Packaged Chillers and PWS Series Air to Water Heat Exchangers provide contaminant-free, cost-effective component cooling without adding heat to the local environment.

Closed-loop liquid cooling efficiently and economically improves performance for advanced manufacturing processes and electronics in hot, dirty environments using field-proven water circulation technology. Designed to guarantee full separation of water lines and airflow paths, Pfannenberg liquid cooling systems feature integrated electronic thermostats and flow control components for accurate temperature control and superior energy efficiency. Liquid cooling offers an ideal cooling solution for spindle motors and automation drives in automotive manufacturing, power plant electronics and solar inverters in energy production, and oven controls and product coolers/dryers in pharmaceutical production, as well as for paper & printing, plastic manufacturing, and water/wastewater applications.

EB 2.0 Large Packaged Chillers

Compact Pfannenberg EB 2.0 Large Packaged Chillers allow maximum cooling capacity in the smallest possible footprint. Heavy-duty finned-tube condensers deliver high efficiency and long service life in hot, corrosive, or dirty ambient environments.

Models range up to 30 Tons, so proper capacity is available for most applications, while all units are ready to use after simple installation—requiring only piping and power. Remote start/stop capability and insulated vented polypropylene reservoir tanks for rapid heat load changes provide reliable and flexible operation.

PWS Air to Water Heat Exchangers

PWS air to water heat exchanger

Pfannenberg PWS Air to Water Heat Exchangers deliver energy efficiency and high cooling capacity with a maintenance-free design for indoor and outdoor applications. Featuring a closed-loop design, PWS Air to Water Heat Exchangers seal contaminants out by isolating ambient air from the internal air circuit.

These units are ideal for extreme environments such as plant washdown areas, and areas with high amounts of particulate, high ambient temperatures, or an oily or aggressive atmosphere. PWS Air to Water Heat Exchangers maintain a UL Tested NEMA Type 12/3R/4 seal against enclosure, and a stainless-steel option offers NEMA Type 4X protection.

 

If a water source is not available on site, facilities can combine Pfannenberg PWS Air to Water Heat Exchangers with Pfannenberg EB 2.0 Large Packaged Chillers for an efficient closed cooling solution.

Reliable Enclosure Cooling for Commercial Bakeries

/in , , , , , , , /by

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.
