Following successful laboratory testing, company begins field testing stage

Trane Technologies (NYSE: TT), a global climate innovator, has surpassed U.S. Department of Energy (DOE) requirements for the Residential Cold Climate Heat Pump (CCHP) Challenge for high-efficiency heating in freezing temperatures. After outperforming in laboratory tests in extremely cold temperatures, the Trane® high-efficiency, cold climate heat pump will begin field trials this month.

“As a sustainability leader, we relentlessly innovate to develop high-efficiency heat pumps and other sustainable solutions that transition away from fossil fuels and reduce carbon emissions,” said Jason Bingham, president of Residential HVAC, Trane Technologies. “We’re excited to move to the next phase of the DOE challenge. As more and more homeowners choose sustainable solutions like heat pumps, we look forward to helping them take advantage of new clean energy tax credits and rebates available through the Inflation Reduction Act.”

When tested at the DOE’s lab, Trane’s CCHP prototype performed in temperatures as low as negative 23 degrees Fahrenheit, surpassing the mandatory negative 20 degrees Fahrenheit DOE requirement.

“When tested at the Oak Ridge National Lab Facility, our prototype pushed the limits of the testing with high performance even as temperatures moved beyond the trial scope. To stop this Trane unit, they had to manually cut the power,” said Katie Davis, vice president of engineering and technology, Residential HVAC, Trane Technologies. “We are excited to conduct field testing with this heat pump and keep families warm while supporting a more sustainable future. It’s hard to stop a Trane!”

Until this new technology is available, the company continues to offer the most efficient options available today including heat pumps, more environmentally minded furnaces, and the pairing of the two in dual fuel systems.

Through bold, industry-leading action, Trane Technologies is creating efficient and sustainable comfort solutions and advancing its 2030 Sustainability Commitments, including the company’s Gigaton Challenge – the largest validated science-based climate commitment related to product use emissions, which pledges to reduce one billion metric tons (one gigaton) of greenhouse gas emissions from customers’ carbon footprints by 2030.

Bundles Combine Unit with Popular Safety, Installation and Control Accessories in One Convenient Package 

Marley Engineered Products, a leading choice among contractors for comfort heating and ventilation systems, is now offering its QMark^® MUH unit heater and Berko^® HUHAA unit heater in ready-to-install PRO Series bundles that include the most commonly-ordered safety, installation and control components to make heating any space effortless.

The MUH-Pro+ and HUHAA Pro+ Series bundles, which include the SmartSeries^® Plus thermostat and B10 mounting bracket, allow for easy mounting and flexibility in controls and integration. The SmartSeries^® Plus thermostat provides connection to BACnet MS/TP building management systems for easy control and monitoring. The bundles also include a 24VAC transformer for immediate connection to a low voltage thermostat or for future integration flexibility.

Ideal for new or replacement applications in factories, warehouses, garages, power stations and mechanical rooms, the MUH and HUHAA Pro+ Series heaters feature an advanced pull-through air flow design that draws air across the heating element for even air distribution and cooler element operation. Its output capacity is so powerful that it is even a suitable option for heating loading docks or other indoor/outdoor transition space.

“By bundling the MUH and HUHAA units with popular accessories, we not only help contractors save time and money, but we also reinforce our commitment to creating simplified solutions that deliver best-in-class performance to make heating a space effortless,” said Andrew Martin, manager of Product Management with Marley Engineered Products. “Simply wire it up and you’re ready to go!  Best of all, the MUH-Pro+ is in stock and ready for delivery… just in time for heating season!”

Bell & Gossett, a Xylem brand, has unveiled an updated version of its Glycol Make-up Unit GF60 (GMU), a pressurized solution designed for closed hydronic heating or cooling systems.

The Bell & Gossett Glycol Make-up Unit GF60 (GMU) is an automated 110V diaphragm pump with digital control. Each engineered package is designed to maintain critical minimum pressure levels to make up for losses that may occur due to leakage. It comes with everything required for easy installation.

“All critical components required for maintenance are easily accessible under a removable top cover,” said Jim Wilkinson, product manager, packaged systems, Xylem Inc. “This eliminates the need to access awkwardly oriented components located on the underside of similar packages on the market.”

The automated system operates as needed to add water or water-glycol solution to a closed loop heating, chilled water, process, snowmelt or radiant heat system.

The versatile unit can handle output pressures from 7.5 to 70 psi and has a self-priming pump.

And unlike a traditional pressure switch, cut-in and cut-out pressure adjustments can be made easily using a digital display.

Digital control enables users to continuously monitor unit performance. In the event of a leak, the system immediately notifies the operator that the fluid level is dropping. The GMU safely shuts off the pump if the storage tank level gets too low, and a pressure relief valve provides protection from excess pressure.

“The package automatically notifies the operator if a leak develops,” said Wilkinson. “There’s also a low level protection that will stop pump operation if the fluid level becomes critically low.”

Additional features include:

• Self-filling system
• A ½-inch connection with a check valve for easy installation
• Translucent polyethylene solution container with lid
• An accumulator tank to prevent excessive pump cycling
• Air vent valve purges air on initial start-up and allows manual agitation of solution
