Introduction (Cont'd)

A 40 mesh strainer (0.5 and 1.5 mm) is recommended upstream of the heat exchanger to 

prevent clogging.

CONDENSER

Coils

 – fin and tube condenser coils of seamless, internally-enhanced, high-condensing-

coefficient, corrosion resistant copper tubes are arranged in staggered rows, mechani-

cally expanded into aluminum fins. integral subcooling is included. The design working 

pressure of the coil is 650 PSiG (45 barg).

Low Sound Fans

 – The condenser fans are composed of corrosion resistant aluminum 

hub and composite blades molded into a low noise airfoil section. They are designed for 

maximum efficiency and are statically and dynamically balanced for vibration-free opera-

tion. They are directly driven, and positioned for vertical air discharge. The fan guards are 

constructed of heavy-gauge, rust-resistant, PVC (polyvinyl chloride)-coated steel wire.

Motors

 – The fan motors are Totally Enclosed Air-over, squirrel-cage type, current pro-

tected. They feature ball bearings that are double-sealed and permanently lubricated.
