FLEX
NOTES:
1. Tonnage ratings conditions: 44°F leaving chilled water temperature, 85°F entering condenser water temperature, fl ow rates are 3 GPM
per ton through the condenser with a fouling factor of .00025 and 2.4 GPM per ton through the evaporator with a .0001 fouling factor.
ff
2. Minimum chiller unloading percentage can be as low as 4.7% of total system. Calculate system unloading by dividing 1/2 of smallest
module by total system tons.
3. Module operational weight includes water, compressor oil, and refrigerant charge. Multiply times the number of modules
for a total system operational weight.
4. Unit shipping weight includes refrigerant charge, compressor oil, and shipping base skid.
5. The minimum/maximum fl ow rates are based on a temperature differential of 7˚F to 15˚F through the evaporator and the condenser.
The minimum allowable temperature differential for the FLEX 65 condenser is 9.5°F.
