HTPG announces new Next-Gen All-Temp Low Profile Unit Coolers

Units feature increased efficiency and service access

Duluth, GA – August 9, 2017 – Heat Transfer Products Group, LLC (HTPG), manufacturer of commercial refrigeration equipment sold under the recognized brands of Russell, Witt, Kramer and ColdZone, announces the release of its new Next-Gen All-Temp Low Profile Unit Cooler line. The new design features high efficiency motors, easy service access, new fan guard design and deep draw venturi to achieve optimal air flow, coils with enhanced copper tubing, and redesigned housing. These models can be used with multiple refrigerants, and are available in air, electric and hot gas defrost configurations.

“The versatile low profile unit cooler is the backbone of the walk-in cooler and freezer industry. HTPG’s new, highly efficient, low profile evaporator provides the perfect complement to the company’s award-winning Next-Gen condensing units, supplying the marketplace an improved platform of split system refrigeration equipment over what is currently available for small to medium walk-ins,” said Paul Westbrook, HTPG’s director of sales and marketing.

Contractors will appreciate that HTPG’s Next-Gen All-Temp Low Profile Unit Coolers are designed to be easier to service. The end panels slide out for quick access to piping and electrical connections. The top pan includes slotted mounting points to simplify installation. Units mount flush to the ceiling to maximize storage space and meet all NSF requirements. The embossed aluminum housing is lightweight, easily cleaned, and durable.

For energy efficiency, Next-Gen All-Temp models include single speed EC motors that can be field or factory wired for dual speed operation. Dual speed EC motors are compliant with California Title 24 requirements. The units feature enhanced copper hairpins for maximum heat transfer while reducing refrigerant charge. Optimal air flow pattern is achieved by the new fan guard design and deep draw venturi.  For increased performance, heavy-duty 12” aluminum fans are balanced to provide vibration-free operation, and fan sections are baffled to prevent short cycling of the discharge air.

Electric defrost models include a defrost termination/fan delay control, heater safety thermostat, and heater that is mounted on the air intake coil face to provide optimal performance and easy maintenance. Electric and hot gas defrost models have heaters affixed to the drain pan, which can be easily removed for service or cleaning. The hinged drain pans include rounded corners for better drainage and easier cleaning. The pans also include a removable ¾” MPT drain fitting installed in the center-rear of the pan for efficient condensate draining, easy field connection and cleaning. Drain fittings can be quickly disconnected for service or replaced without changing the entire drain pan.

Single fan through six fan models are available with air flow spanning from 800 to 4,650CFM in air, electric or hot gas defrost versions for 115V, 115-230V/1, 208-230V/1,208-230V/3 or 460V/1 60 Hz power. These unit coolers can also be used for 50 Hz operation. EC motors are standard but PSC motors are also available. All motors include thermal overload protection for efficient, energy saving operation. Pre-assembled, factory-installed options include liquid line solenoid valves, mechanical expansion valves, mechanical room t-stats, and copper tee. Optional features include coated housing, coated fin pack, adjustable termination/fan delay control, insulated drain pans and more. Most models and options will be available for quick shipment directly from the factory and finished goods warehouses across the country.
