Increased part-load perfor-
mance reduces operating
costs
Multiple compressors — Multiple
compressors on a refrigerant cir-
cuit further enhance part-load effi-
ciency. This allows compressor to
operate fully loaded with 100% of
cooler and condenser surface active at
50% unit capacity, optimizing evapo-
rating and condensing temperatures.
Since the chiller normally works at
part load for 97% of its operating
time, a substantial reduction in operat-
ing cost can be realized.
Suction cutoff unloading — Un-
loading on 06E compressors eliminates
unnecessary pumping of refrigerant
gases during unloader operation. This
substantially reduces part-load power
consumption.
Liquid refrigerant subcooling —
Integral subcooler uses coldest
condenser fluid to increase system
capacity without extra horsepower.
