    Packless 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 chiller and evaporator coils are approved by Underwriter's Laboratories, Inc. (U.L.) and the Canadian Standards Association (C.S.A.) for use with the following refrigerants:


    Packless chiller and evaporator coils are covered by one or more of the following U.S. patents: 5409057, 5551504, 5311661.
