Air conditioning system

Use environmentally friendly R-410A HFC refrigerant in a range of sizes from 10 to 140 tons with the Ecosaire from Dectron. The LEED-qualifying conditioner meets NC-30 and NC-40 noise criteria. The conditioner's true glycol-cooled system uses cool outside air when temperatures fall below 60 F without using refrigeration compressors, hot-gas bypass valves, or increased fan motor horsepower.

Use environmentally friendly R-410A HFC refrigerant in a range of sizes from 10 to 140 tons with the Ecosaire from Dectron. The LEED-qualifying conditioner meets NC-30 and NC-40 noise criteria. The conditioner’s true glycol-cooled system uses cool outside air when temperatures fall below 60 F without using refrigeration compressors, hot-gas bypass valves, or increased fan motor horsepower. The conditioner’s precision comfort control (PCC) features dual cooling capabilities for chilled water systems capable of supplying room load conditions. The PCC also uses DX cooling with a choice of air, water, glycol-cooled, or dedicated chiller water systems for heat rejection.
