Coaxial coil heat exchanger for Vessel

Coaxial coil heat exchanger 1. Turbulence imparted by the convolutions to both the water and refrigerant flows for control fouling to be sink in surface.The net result is a highly effective,compact heat exchanger with superior anti-fouling characteristics. 2. The water and refrigerant are converse flow to makes excellent heat transfer effective of heat exchanger when condensing. 3. Standard sizes is conducive to saving space for nominal 6000BTU through 84000BTU. 4. The inner tube can be made of copper or B10 cupronickel, shell tube in steel.Copper inner tube is available in fresh water and cooling tower application while cupronickel is available for ground and sea water application. 5. Extek coaxial coils are approved by Underwriters Laboratories,Inc.(U.L.)for use with refrigerants R12,R22,R407c R410a and other new refrigerants.
