LV Case Study

Much of the apple crop grown in the Pacific Northwest of the United States is stored in Controlled Atmosphere (CA) refrigerated warehouses. Colmac has successfully developed specialized industrial ammonia refrigeration air coolers which are widely used in the CA fruit storage industry.

In 1997, a large refrigerated apple storage and packing facility was constructed with 22,000 square feet of CA storage, 8,000 square feet of common storage, and 3,000 square feet of packed fruit handling and storage. Colmac air coolers were specified for the entire facility.

Colmac LV (Low Velocity) coolers were installed in the packed fruit handling and storage room because of limited headroom, low noise, and low air velocity requirements. Installed cost of the 2 x LV12 coolers turned out to be substantially lower than the 4 x ICL units originally proposed due to lower first cost, and lower installation costs (fewer vessels and less piping).

Optional Variable Frequency Drive (VFD) compatible motors were provided on all the Colmac coolers. Control of fan motor speed is accomplished through the computerized building automation system in response to room loads.
