Refrigerants for Bus and Rail

Reliable and Safe Refrigerants for Public Transportation

Today's populations are growing rapidly. As the world continues to urbanize, sustainable development depends increasingly on meeting the transportation needs of city dwellers.

Many city governments have added more public transportation to alleviate traffic congestion and improve the quality of life for their citizens. These bus and rail systems require reliable, consistent, and efficient air conditioning (AC) systems that operate in diverse conditions to maintain comfortable, healthy environments. Public transit relies on refrigerants to deliver uninterrupted, efficient cooling.

Passenger Comfort and Environmental Sustainability with Opteon™ Refrigerants

The performance of an AC system depends on the refrigerant it uses. When it comes to comfort cooling in public transportation, it's especially important to use a high-performing refrigerant that can stand up to continuous use and keep passengers comfortable.

Traditionally, bus and rail AC use hydrofluorocarbon (HFC) and hydrochlorofluorocarbon (HCFC) refrigerants with high global warming potential (GWP). Public transit running on these outdated refrigerants will produce harmful emissions that can damage the environment, contributing to global warming and ozone depletion.

However, Opteon™ refrigerants—a new generation of non-ozone depleting hydrofluoroolefin- (HFO) based refrigerants—have up to a 99% lower GWP than many of the HFC and HCFC refrigerants they replace. They also offer the best balance of properties, safety, and performance for bus and rail AC systems.
