The plant had no dedicated MUA system to balance all of the exhaust, and the compressed air heat was being discharged to the outside all winter. The 2– 50HP units had a ductwork system installed with controls to optimize outside air and utilize the heat to balance the plant.
The recovered heat was then directed to a nearby area for parts drying to speed production. The compressor room itself also was controlled to prevent freezing in winter.
Heat recovery off the 2– 50HP compressors was added to add MUA and heat to the plant in winter. Both compressors were integrated in the system, which also controls room temps to a min of 40F and automatically uses the heat when temps drop below 50F outside.
