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.
