The Packless CDAX Series of coaxial condensers are designed specifically
to remove heat from the refrigerant discharge vapor of air conditioning,
refrigeration, or heat pump systems for the purpose of heating
potable water. The CDAX Series employs a "tube-in-tube" design: Potable water flows inside a double-wall convoluted copper tube
in a counterflow direction to the refrigerant vapor flowing in
the annulus between the convoluted tubing and the smooth outer
steel tube, called the shell. This counterflow path provides the
greatest temperature difference between the two fluids to yield
optimum heat transfer. The CDAX Series utilizes nested double-wall convoluted tubes having
multiple leads: The double-wall isolates the refrigerant from the water to prevent
contamination of the water in case of a leak in the convoluted
tubing. The convolutions impart turbulence to both the water and
the refrigerant flows, while offering all prime surface for maximum
heat transfer area with minimum heat exchanger size.
Packless CDAX Series Double Wall Condensers are constructed in a compact helical design. The following models are available.
The CDAX Series are approved by Underwriters' Laboratories. Inc.,
(U.L.) and the Canadian Standards Association (C.S.A.) for use
with potable water. |
