Packless Industries

Seven standard models are available ranging in capacity from 1 to 5 tonsStandard models are coaxial tube-in-tube design with a convoluted inner tube of copper and an outer tube (shell) of steel or copperC-UL approvedISO 9001:2008 certifiedWorking pressures:CHAX-3100-H thru CHAX-3400-H:Refrigerant side: 650 psigWater side: 400 psigCHAX-3500-J:Refrigerant side: 620 psigWater side: 400 psigPackless chiller and evaporator 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 chiller and evaporator 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.

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.
