The most reliable HVAC system for transit is now better than ever.
High performance and reliability for more than 30 years. T-Series: The HVAC design that changed an industry.
Performance proven components provide long service life and minimum maintenance for low life cycle costs.
Lightweight all-aluminum frame, blowers, coil headers, and compressor reduce bus stress and fuel consumption.
Convenient service access to all major components. Simplified electrical troubleshooting with microprocessor controls. Removable access panels and a convenient rear window location provide easy access to unit components for repairs or maintenance.
T Series units have many of the same internal components in the electrical and refrigeration systems, assuring a readily available supply of parts and parts interchangeability to lower costs and minimize downtime.
T Series units are easy to install and service because of the compact, one-piece design.
You know you’re getting a dependable, reliable bus air conditioning and heating system that can lower your operating and maintenance costs and keep your bus riders cool.
For use on standard diesel engine-driven buses.
For use on hybrid electric and all-electric buses.
