Condenser Coils

Packless water-source condenser coils operate very effectively as either refrigerant condensers or refrigerant evaporators when transferring heat with water. This makes them an ideal choice for both water-source heat pumps and water-cooled condenser applications.
The 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 water-source condenser coils is achieved with a counterflow arrangement of water and refrigerant during condensing.
