Condenser Coils

Replacement condenser coils for all types of Refrigerants. 

Primary Surface

Round seamless copper tubes are mechanically expanded into the fin collars of the secondary surface. The mechanical expansion provides a permanent metal-to-metal bond for efficient heat transfer. Tubes are staggered in the direction of airflow

Headers

Seamless copper with die-formed holes that provide a parallel surface to the coil tube for strong brazing joints.

Connections

Copper O.D. sweat with standard arrangement for one compressor circuit. FACE SPLIT circuiting available for two or more compressors.

Casing

Using 16-gauge minimum thickness material, 1 1/2" flanges are die-formed to permit easy stacking and mounting. Intermediate tube supports are supplied on coils over a certain height and length

Casing Material Options:

Full 16 gauge galvanized steel standard with optional stainless, aluminum and copper.

Testing & Performance

All coil assemblies are leak tested under water at 500 PSIG air. All coil assemblies Nitrogen charged for shipping.

PERFORMANCE IS CERTIFIED under ARI Standard 410.
