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 hairpin bends.

 5/8” o.d. options ( tube wall thickness / return bend thickness ) ( .020” / .028” ) ( .025” / .035” ). Tubes are centered on 1.50” in the tube face and 1.299” between rows.

½” o.d. ( tube wall thickness / return bend thickness ) ( .017” / .025” ). Tubes are centered on 1.25” in the tube face and 1.083” between rows.

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

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.

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

½” tubes come standard with aluminum fin .006” thick with optional copper fin thickness of (.006). Fins per inch available are 8 through 14.

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 ga. minimum thickness material, 1 ½” 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”.

Full G-90 galvanized steel standard with optional 304 & 316 stainless steel.

All coil assemblies are leak tested under water at 450 PSIG nitrogen.

PERFORMANCE is CERTIFIED under ARI Standard 410. All coil performance ratings are according to Temtrol’s ARI certified selection software.
