ACFX (203 - 522 Tons)

Available from 203 to 522 tons, these units feature superior quality and many unique design advantages. Due to the many superior engineering features listed below, these units "average" 10.3 EER, which is over 8% higher than ASHRAE 90.1 minimum EER.

Exceptional design features are:

• Higher capacity and higher EER achieved with the same compressor. A 13% increase in capacity with only a 3.5% increase in power when compared to a direct expansion cooler.
• Better part load performance due to micro-computer control of refrigerant level to keep evaporator tubes immersed in boiling refrigerant with no loss of surface for super heat or oil return as in direct expansion coolers.
• Flash economizer / vapor injection cycle providing up to 25% increase in capacity with only 10% to 15% increase in compressor kW, resulting in higher EER.
• Excellent capacity modulation in response to building loads due to variable orifice control of refrigerant feed to evaporator that can maintain ±½ °F leaving water even at low loads due to micro-processor control.
• Maximum reliability and redundancy with compressor isolation by check valves and stop valves eliminating cross contamination due to faulty compressor and ensuring maximum redundancy.
• Cleanable Cooler with removable heads for tube cleaning with brushes to maintain unit efficiency due to low tube fouling.
• Lower water side pressure drop on flooded cooler vs. equivalent direct expansion cooler results in less pump horsepower and leading to improved system efficiency.
• Cross condenser coils minimize wind effect and fin damage while maximizing condenser surface, allowing more compact unit without enhanced fins that tend to lose efficiency over time.

The ACFX line of Air-Cooled Flooded Chillers are all built on rigid steel bases to prevent unit deflection and coil damage during rigging. All compressors are mounted in an insulated compartment to reduce noise breakout. You will be proud to own these fine units.
