Trane announced today that as of January 1, 2025, all Trane 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.
