Despite this increase, which achieves a greater capacity, the unit’s performance is more energy-efficient at part loads. Each fan is driven by a variable frequency drive (VFD) designed to run at part loads rather than cycling on and off when the demand changes. With VFDs, the unit can run all four fans at, for example, 30 ...
The water-cooled units at Western Gateway are designed for maximum energy efficiency with variable frequency drives (VFDs) on all motors. The cold climate in northern Utah also requires freeze protection, so each Evapco fluid cooler feeds 40% propylene glycol to its LCR unit and maintains efficiency through advanced wet cooler design and ...
