HTPG Announces New Next-Gen WC-Series Water Cooled Condensing Units

Units feature increased efficiency and easy access for service


Duluth, GA – March 14, 2018 – Heat Transfer Products Group, LLC (HTPG), manufacturer of commercial refrigeration equipment sold under the recognized brands of  Russell, Witt, Kramer and ColdZone, announces the new Next-Gen WC-Series Water Cooled Condensing Units. The new models incorporate design features from the award-winning Next-Gen ½ to 6 HP Air Cooled Condensing Units and offer greater serviceability, performance, and are compatible for use with low global warming potential (GWP) refrigerants.

“These new condensing units are a significant improvement over the legacy water cooled models,” said Paul Westbrook, HTPG’s director of sales and marketing. “Improvements include mechanically formed pre-bent tubing for reduction of potential leaks, high efficiency water cooled coaxial condenser and heat exchange for better performance, and several features that make servicing and maintenance much easier.” The units have base mounted shut-off valves, a large electrical control box with a hinged and removable door, color-coded wiring and an easy-to-read point-to-point wiring diagram. The control box has ample space for optional components.

Next-Gen WC-Series standard models are offered with hermetic or scroll compressors and include the previously mentioned improvements along with features such as a liquid line kit with filter and sight glass with moisture indicator; suction line piping; refrigerant receiver with isolation valve and pressure relief plug; adjustable dual pressure (auto reset) controls; electronic defrost timer with defrost contactor on low temperature models; and electronic air defrost timer on medium temperature models. A host of optional components are available to further customize the units to match the specific refrigeration need: Cupronickel heat exchanger and water piping; air or electric defrost provisions; replaceable core liquid and suction filters; suction accumulator; oil separator; water regulating valve; phase loss monitor; non-fused disconnect; two-tier stacking rack; and more.

The versatile units are designed to utilize R404A, R407A, R407C, R448A and R449A refrigerants. The models are UL and cUL listed and are available as extended medium or low temperature models.
