Heat Reclaim and Condenser Coils

Download Specs Sheet

Condenser coils are another of the components of the mechanical refrigeration cycle.  In the heat transfer process the condenser coil is the opposite of the direct expansion coil.  Heat is transferred from the refrigerant in the tubes to the air through the fins on the coil.  Most condenser coils are designed with either 1/2″or 3/8” O.D. tubes.  Commercial Coils’ condenser coils designed to handle all refrigerants including HFCs and HCFCs.  Because these coils are generally outside in the elements, we offer condenser coils built to meticulous spec standards that ensure longer life.  We also offer coil coatings that will help protect against harsh or salt water environments.

Primary

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 and only return bends are used – NO reduced tube wall in the bend radius by using hairpin bends.
Tube Size Options:

5/8″ O.D. x .020″ wall thickness standard with optional wall thickness of (.025) (.035) and (.049). Centerlines are 1.5″ in the tube face and 1.299″ between rows.

1/2″ O.D. x .017″ wall thickness standard with optional wall thickness of (.025). Centerlines are 1.25″ in the tube face and 1.083″ between rows.

3/8″ O.D. x .016″ wall thickness standard with optional wall thickness up to (.035). Centerlines are 1″ in the tube face and .866″ between rows.

Rows available are 1, 2, 3, 4, 5, 6, 8, 10 and 12.

We have over 20 different surfaces available. Please contact us if construction other than what is above is needed.

 

Secondary

Corrugated plate type fin that is die-formed. Fin collars are full-drawn to provide accurate control of fin spacing and maximum contact with tubes.
Fin Material Options:

5/8″ tubes comes standard with aluminum fin .008″ thick with optional (.010). Optional copper fin thicknesses available are (.006) (.008) and (.010). Fins per inch available 6 through 14.

1/2″ tubes come standard with aluminum fin .006″ thick with optional copper fin (.006). fins per inch available 8 through 14.

3/8″ tubes comes standard with aluminum fin .0055″ thick with optional thicknesses available. Copper fin thicknesses available start at .0055″.

Fins per inch available 6 through 16.

Contact us for availability of other patterns, fin materials, and/or thicknesses.

 

Seamless copper with die-formed holes that provide a parallel surface to the coil tube for strong brazing joints.
Copper O.D. sweat with standard arrangement for one compressor circuit. FACE SPLIT circuiting available for two or more compressors.
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 44″ fin length with an additional support every 42″ multiple thereafter.
Casing Material Options:

Full G-90 galvanized steel standard with optional stainless, aluminum and copper.

All coil assemblies are leak tested under water at 500 PSIG air.

PERFORMANCE IS CERTIFIED under ARI Standard 410. All coil performance ratings are according to Commercial Coils, Inc.’s ARI certified selection software.

 

 

Whether you need standard coils or customized, we can meet your specific requirements.
