Next Generation HVAC: The Effect of Fully Electric HVAC Systems on the Transit Bus Market

The introduction of advanced technologies on buses is changing the transit industry. Component manufacturers are able to utilize medium voltage electricity (220-480VAC) available on hybrid electric and fuel cell vehicles. SUTRAK recognized early, the pending opportunity for fully electric HVAC systems capable of running from an onboard power source. Drawing from experience with electric HVAC systems for Light Rail Vehicles & Automated People Movers, company design engineers successfully developed the UEPAC (Unitary Electric Packaged Air Conditioning) system for transit bus applications. Our patent applications were approved and patents were awarded for both rear and roof designs. During the design & development of these systems, other discoveries were made, which allow them to run on more traditional fuel applications. SUTRAK unveiled this new technology to an eager audience at the 2002 APTA show in Las Vegas. These systems have powerful positive ramifications for Bus OEM’s, Transit Authorities, and regulatory agencies. Certainly, they have the ability to dramatically change the industry landscape in the future.
