From Doucette Industries Inc., a coaxial coil has deeply fluted copper or cupronickel tubing to maximize heat transfer and minimize scaling and fouling. Coils can be used as a condenser or evaporator, making them suitable for heat pump applications. The units are engineered for use with R-22, R-134a, R-404a and other freon refrigerants. CBX direct expansion liquid chiller uses enhanced copper tubing for heat transfer efficiency. The systems avoid freeze-ups and are suitable for a range of process cooling applications. Rated at 2.4 gal/min per ton, the units are suitable for low temperature glycol applications.
