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
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.
