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.
Split System: Typically
applied to Rapid Transit and Commuter equipment these systems
consist of two evaporator units – usually
mounted in the ceilings at each end of the cars – and
an underfloor compressor/condenser unit, which also carries
the electronic control box assembly. Following are examples
of our contracts using this technology. Typical capacities
of these units range from 10 to 15 tons.
