8. Required to provide stable operation. Storage/buffer tanks in return piping may be utilized to meet the minimum volume requirements.
Main header water/fluid connections are 6" grooved coupling for the 30, 50 and 70 ton modules. The 85 ton module uses 8" grooved couplings.
85 ton module cannot be directly coupled with 30, 50 or 70 ton modules due to a difference in header and frame size.
Module operational weight includes water, compressor oil, and refrigerant charge. Multiply times the number of modules for a total system
operational weight.
Tonnage ratings conditions: 44°F leaving chilled water temperature, 85°F entering condenser water temperature, flow rates are 3 gpm per ton
through the condenser with a fouling factor of .00025 hr-ft2-°F/Btu and 2.4 gpm per ton through the evaporator with a .0001 hr-ft2-°F/Btu fouling
factor.
Ratings in accordance with AHRI Standard 550/590.
The minimum/maximum flow rates are based on an approximate temperature differential of 5°F to 20°F through the evaporator and 5°F to 30°F
through the condenser. Flow rates vary based on application; verify with selection software.
