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
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 a certain height and length
Full 16 gauge galvanized steel standard with optional stainless, aluminum and copper.
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.
We have over 20 different surfaces available. Please contact us if construction other than what is above is needed.
Corrugated, louvred and sine wave plate type fin that is die-formed. Fin collars are full-drawn to provide accurate control of fin spacing and maximum contact with tubes.
Contact us for availability of other patterns, fin materials, and/or thicknesses.
