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.”
