Packless double wall condenser coils are designed specifically to remove heat from the superheated refrigerant discharge vapor of air conditioning, refrigeration, or heat pump systems for the purpose of heating potable water.
The CDAX series of coils utilize a "tube-in-tube" design where 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 an the smooth outer steel tube which provides efficient heat transfer and minimizes fouling.
Packless double wall condenser coils are C-UL-US listed for refrigerant side working pressures of 650 psig and water side working pressures of 500 psig.

Packless Desuperheater coils utilize a coaxial "tube-in-tube" design. Water flows through the inner tube while refrigerant flows in the annulus between the inner and outer tubes.
The key to the high performance of Packless coils lies in the convoluted multi-lead inner tube manufactured in a patented process. The resulting convoluted tube has increased heat transfer surface area per unit length yet still permits full flow of both water and refrigerant around its entire periphery for improved performance.
Turbulence imparted by the convolutions to both the water and refrigerant flows further enhances the thermal performance, while inhibiting the accumulation of deposits on the surfaces. The net result is a highly effective, compact heat exchanger with superior anti-fouling characteristics.
Optimum heat transfer with Packless Desuperheater coils is achieved with a counterflow arrangement of water and refrigerant during condensing.
For non-standard applications, Packless Desuperheater can be obtained on a special order basis with different capacities, mounting brackets, and fittings. Tell us what you need and our engineers will assist in making it happen.
