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,
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.
Locomotive System: Typically
comprises two basic systems, both fully self contained, with
the objective of cooling the cabs. They
contain the required evaporator, compressor/condenser and control
system. The underfloor system is located under the cab floor
in a compartment provided by the locomotive builder, while
board unit sits on the running board outside of the cab. Typical
capacity is 3 tons.
TTA has also undertaken a contract in this market segment, with
CSX, where the unit is leased to the customer for a period of
ten years, each unit is called in for maintenance annually, and
a mid life overhaul at five years.
