Condenser Coil

Condenser coils are used to reject heat from an air-conditioning or refrigeration system. Sometimes they are used with the intention to heat air streams. They are one of the four main components in the refrigeration or air-conditioning cycle. Refrigerant enters as a superheated gas and condenses in the coil tubes as the air is heated. The refrigerant leaves the coil as a liquid.

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

Secondary Surface
Corrugated aluminum or copper plate type fin that is die-formed. Fin collars are full-drawn to provide accurate control of fin spacing and maximum contact with tubes.

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

Connections
Copper outside diameter (O.D.) Sweat with standard arrangement for one compressor circuit. FACE SPLIT circuiting available for two or more compressors.

Casing
Casing is die-formed with 1½” flanges to permit easy stacking and mounting. Intermediate tube supports are supplied on coils over 44” fin length with an additional support every 42”.

Testing
All coil assemblies are leak tested under water with nitrogen at 400 PSIG.

Circuiting
Coil circuiting options include: full face (std.) and horizontal (face) split.
