Carrier Introduces New Line of Hybrid Heat Light Commercial Rooftop Units

Carrier has expanded its WeatherMaster® line of light commercial packaged rooftop units with a new hybrid heat option for improved performance in colder climates. Carrier is a part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions. 

The 48QE dual fuel units are available from 3-25 nominal tons. The new design utilizes the electric heat pump as the primary heating source in milder conditions and switches to a natural gas furnace for auxiliary heating when temperatures drop significantly. The hybrid system automatically selects the most efficient heat source based on outdoor temperature to ensure occupant comfort. 48QE units can use both electric and gas heat simultaneously or switch between the two heating sources, helping to ensure optimal performance and lower energy consumption. Units can operate as a heat pump, hybrid heat unit or as a gas heat unit. 

The 48QE is meant to provide: an easy, cost-effective retrofit option for light commercial applications by fitting onto existing curb and ductwork with minimal modifications required. It is also designed to maintain indoor temperatures and comfort while maximizing efficiency and reducing environmental impact. In addition to a more efficient fuel source, the EcoBlue™ fan technology features 75% fewer moving parts than legacy belt-driven systems, leading to 40% less energy used. 

“The 48QE can operate in three different configurations, giving our customers added flexibility in fulfilling their heating and sustainability requirements without the need for manual adjustments,” said Heidi Gehring, Managing Director, Light Commercial Solutions, Carrier. “Carrier is committed to providing solutions that offer the energy efficiency and performance our customers want with the intelligence to help them meet those goals.” 

The 48QE features SystemVu™ controls that can operate with a traditional thermostat or connect directly to a building automation system. It is designed to be used with lower GWP* R-454B, also known as Puron Advance™.

*According to the IPCC’s Fourth Assessment Report (AR4) of 2007, R-454B has a 466 GWP100. GWP is a measure of a substance’s climate warming impact compared to CO₂.
