Double Walled Heat Exchangers

DW HEX Double Walled Copper Coil

Double walled copper coiled heat exchangers with visible
leak detection are designed to minimize the chance of cross
contamination of your domestic water from Glycol or similar
products. As your boiler water flows through the steel tank
in a counter flow motion it passes over the multiple
copper coils that carries your domestic water resulting
in an unlimited amount of hot water. Copper coils are
 excellent for high heat transfer eciency. The DW
exchanger easily fits in with your mechanical design
utilizing your boiler, geothermal, solar applications, radiant
floor/wall and baseboard.
AMI manufacture a wide range of model’s with flow rates
ranging from 2.5gpm up to 30 gpm and ranges of 112,500
to 1,352,000btu/hr Advance Metalpres Inc. has all your
hot water demands covered.


Features:
★ High quality double-walled copper coil with
LEAK DETECTION
★ Two-pass design for high heat transfer coefficient
★ Heavy Duty Mild Steel Shell and base design.
★ Powder-coated steel jacket for high quality finish and durability.
★ Unit Stands on the floor for ease of installation.
★ Non-toxic fiberglass insulation.
★ All connections are female couplings for quick and simple installation
