Notes:
1.
Unit tonnage ARI rating conditions: 44°F leaving chilled water temperature, and 2.4 GPM per ton through the evaporator; 95°F entering condenser air temperature
(dry bulb); 30°F condenser “TD” and 15°F liquid subcooling.
2. Module operational weight includes water, compressor oil, and refrigerant charge. Multiply times the number of modules for a total system operational weight.
3. Unit shipping weight includes compressor oil and packaging.
4.
Main header water/fluid connections are ASME, 6” schedule 40 pipe with grooved couplings, 300 psig maximum working pressure.
5.
The minimum/maximum flow rates are based on a temperature differential of 5.5°F to 20°F through the evaporator.
6.
Minimum chiller unloading percent can be as low as 4.8% of total systems. Calculate system unloading by dividing ½ of smallest module by total system tons.
7.
Remote condensers shipped with a nitrogen holding charge. See page 32 for estimated field charging of refrigerant.
