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 EcoNet Enabled Unit Coolers. Developed in conjunction with Rheem Manufacturing, it builds on the success, reliability and efficiency of Rheem’s EcoNet technology and brings it to the commercial refrigeration market.
“Rheem developed a powerful, customizable tool with the EcoNet platform. We’re excited to bring that technology redesigned specifically for commercial refrigeration applications to our customers. It gives them a higher level of efficiency and more control of their walk-in units for greater energy savings,” said Paul Westbrook, HTPG’s Director of Sales and Marketing.
space temperature control
“We are very happy with the collaboration with HTPG on this new application of our EcoNet controller and working together on more product advancements,” said Mike Branson, Executive Vice President and General Manager, Rheem Air Operations.
EcoNet Enabled Unit Coolers are intelligent, electronically operated evaporators for walk-in coolers and freezers designed for energy efficiency and easier installation. The EcoNet technology saves energy in refrigeration systems through precise superheat and space temperature control, fan cycling, and controlling how often the system goes into defrost based on compressor runtime.
reduces temperature fluctuations
The controller can be used with up to four groups with up to six evaporators per group wired on a single bus
It eliminates unnecessary defrosts, maximizes energy efficiency with less compressor runtime, reduces liability by eliminating icing issues, reduces fan speed to 50% during off cycle to save energy and reduces temperature fluctuations by regulating defrosts for improved product quality. EcoNet Enabled Unit Coolers can be configured to work on a single or dual evaporator coil, and can be used with a condensing unit in single and multiple evaporator installations as a group.
The controller can be used with up to four groups with up to six evaporators per group wired on a single bus. The controller features a back-lit heated, two-row LCD display screen on the controller board that serves as a basic full text user interface to specify space temperature and superheat setpoints, check temperature status, view alarms, select refrigerant, force a defrost, and more. Supported refrigerants include R404A, R407A, R407C, R448A (default), R449A/B, R450A, R507, and R513A.
additional unit cooler
The controller replaces the TXV, liquid line solenoid valve, room thermostat, time clock and defrost termination and fan delay. The controller is now available factory-installed on Next-Gen All-Temp Low Profile Unit Coolers and will be available for quick shipment directly from the factory and finished goods warehouses across the country. Installation in additional unit cooler models will be added in the coming months.
