Thermal-Pak® Coil
EVAPCO's Thermal-Pak® coils are manufactured with a unique elliptical
profile. The special coil design provides for a closer tube spacing
which makes more tube surface available for heat transfer.
Evapco's
coils are manufactured within the most stringent of quality control
procedures. Each circuit consists of high quality steel tubing formed
into a continuous serpentine circuit. Each circuit is then inspected
and tested prior to being welded into a framed coil assembly. The coil
assembly is then  pneumatically
tested at 400 psig under water to ensure it's integrity. The entire
coil assembly is then hot-dip galvanized for industrial strength corrosion
protection.
Note:
Closed circuit coolers should only be used on sealed, pressurized systems.
Continual aeration of the water in an open system can cause corrosion
inside the tubes of the cooler leading to premature failure.
