2-3 Standard Features

Mechanical Features

Compressor. Hermetic scroll compressors are used on 2 hp through 30 hp (1.49 through

23.37kW) models. Semi-hermetic discus compressors are used on the 35 hp and 40 hp (26.20 and 29.83 kW) models.

Evaporator. Stainless steel copper brazed plate evaporators are used on 2 hp through 30 hp models. Shell and tube evaporators are used on the 35 hp and 40 hp models.

Air-Cooled Condenser. Aluminum fin/copper tube with washable filters, package unit only.

Water-Cooled Condenser. 2 hp to 7.5 hp models use tube-in-tube condensers. 10 hp to 40 hp use cleanable shell and tube condensers. All come with cooling water regulating valves for cooling tower water or city water.

Remote Air-Cooled Condenser. 5 hp to 50 hp only. Aluminum fin/copper tube with low ambient control down to –20ºF (-29ºC) via pressure-actuated fan staging and a variable-speed primary fan.

Reservoir. 2 hp and 3 1/2 hp models use a 6 gallon polyethylene tank. 5 hp and 7.5 hp models use a 20 gallon polyethylene tank. 10 hp and 15 hp models use a 40 gallon polyethylene tank. 20 hp to 30 hp models use an 80 gallon polyethylene tank, and 35 hp and 40 hp models use an 80 gallon stainless steel tank.

Piping. Non-ferrous piping for 2 hp through 30 hp models. 35 hp and 40 hp models have ferrous piping.

Pump. Non-overloading ODP motors, horizontally mounted stamped stainless steel or cast bronze construction.
