Carrier Launches New WeatherMaster Rooftop Line

Now featuring lower-Global Warming Potential Puron Advance™ refrigerant

Charlotte, N.C. -

Carrier has launched a new line of V-Series WeatherMaster® Applied rooftop units available with more environmentally sustainable R-454B refrigerant, known commercially as Puron Advance. Carrier is a part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions. 

The V-Series, which includes the 48V with gas heating and electric cooling and the 50V with electric cooling with optional electric or hydronic heat, can integrate with both legacy curbs and select competitor models in replacement or retrofit applications. 

The series is available in 27.5 to 100 ton nominal cooling capacities and features a direct drive indoor fan array with electronically commuted motors, a standard capacity variable speed scroll compressor, Carrier SmartVu™ controls with a 7-inch touchscreen display, a refrigerant leak detection system with dissipation control, and a variety of factory installed options, including modulating gas or electric heat, and Humidi-MiZer® dehumidification. The series also offers selectable configurations for staged air volume in single-zone applications, as well as variable air volume options suitable for both single-zone and multi-zone applications. 

“The Carrier V-Series rooftop units are designed to provide customers with a flexible, efficient and reliable solution for their air conditioning and indoor air quality needs, while also offering easy installation and compatibility with existing curbs,” said Michael Jones, Product Manager, Applied Packaged Systems, Carrier. “And by adopting R-454B, we’re helping our customers prepare to meet regulatory requirements while also designing our products to be efficient and innovative. Puron Advance shows our commitment to going beyond the minimum, surpassing the EPA’s lower GWP requirements for 2025.” 

R-454B has a GWP100 of 466 according to the Intergovernmental Panel on Climate Change Fourth Assessment Report — a 75% reduction from R-410A — and non-ozone depleting potential, the refrigerant was selected as one of the best solutions to minimize environmental impact and provide longevity based on the United Nations Montreal Protocol Kigali Agreement phasedown plan. GWP is a measure of a substance’s climate warming impact compared to CO2.
