DAVIDSON, N.C., September 13, 2024 – As of January 1, 2025, all commercial chillers for comfort cooling and heating, packaged and split system HVAC units must ship with Low Global Warming Potential (GWP) Refrigerants to meet the U.S. Environmental Protection Agency’s Hydrofluorocarbons (HFC) phase-down requirements.
“At Trane, we believe performance and sustainability can coexist. Transitioning to low-GWP refrigerants is one of the most effective decarbonization strategies for commercial buildings. Trane is quickly transitioning its product lines, so our customers have the solutions they need to help successfully comply,” said Oakley Roberts, Vice President of Product Management, Trane.
Trane Adds Factory-Installed Leak Detection Systems to Help Meet Safety Standards
According to safety standard UL60335-2-40, ducted HVAC systems with more than 3.91 pounds of R-454B refrigerant charge must include one or more refrigerant detection sensors. Trane is adding factory-installed leak detection systems to models with more than 3.91 pounds of refrigerant charge. In addition, those systems will be equipped with Building Automation Systems (BAS) points so building engineers can use the integrated Symbio® Controller to help detect and mitigate leaks.
Trane has updated the following product lines with R-454B refrigerant and standard factory-installed leak detection system on models with more than 3.91 pounds of refrigerant charge:
- IntelliPak® 3 Rooftop Units
- Axiom™ Horizontal and Vertical Water Source Heat Pumps
- Axiom Vertical Stack Water Source Heat Pumps
“Factory-installed leak detection systems help give contractors and engineers peace of mind, save time and money by not having to install leak detection systems in the field, and help give them confidence that low-GWP systems are operating safely and efficiently on day one,” adds Roberts.
More Trane Chillers, Chiller Heat Pumps Now Available with Next-Generation Refrigerant
Trane® air-cooled and Thermafit® modular units are designed to help reduce direct and indirect greenhouse gas emissions. With higher efficiency and the use of low-GWP refrigerant, they help owners comply with changing regulations and help meet sustainability goals. The following product lines have changed over to low-GWP refrigerants:
- Trane Air-Cooled models ACS, ACX, and CGAM are available with R-454B refrigerant.
- Trane Air-Cooled model ACR is available with R-513A refrigerant.
- Thermafit Modular-Unit Chillers models AXM, WXM, MWC, MWS, and AMC are now available with R-454B refrigerant.
Trane® Air Handling Units Now Available with Next-Generation Refrigerants
Transitioning products to next-generation low GWP refrigerants is an important part of Trane’s climate commitment. In alignment with this commitment, all Performance Climate Changer Air Handling Units (models UCCA, CSAA, PSCA, TCFS, TCPA) are now available with A2L refrigerants.
