HVAC Systems – New

TTA designs, builds and tests all types of modern HVAC systems available for installation in both new and rehabilitated rail and transit passenger cars, as well as locomotives (both freight and passenger). TTA has been supplying these systems to the industry for more than ten years, and has now successfully delivered, or is building, almost 2,300 new HVAC units.

These systems are developed to the most exacting standards working closely with our customers at the design and prototyping stage to ensure the integrity of production units
We also provide installation and ongoing maintenance services for both our new and overhauled HVAC systems.
TTA has experience in all three types of systems typically applied to rail transit passenger cars, and two types of systems applied to Locomotives.

Roof Mounted System: Typically used in Light Rail Vehicles, these units are fully contained in units that are mounted on the roof of the car. The unit contains the evaporator, compressor/condenser unit and the system controls. Typical capacities of these units range from 8 to 10 tons.
