Unit Description
Trane T-Series Climate Changers
®
are Central
Station Air Handlers designed for a variety of air
handling applications. The basic unit consists of a
fan, heating and/or cooling coils, filters, and
dampers. See the sales catalog (CLCH-DS-9) for a
list of available options and components.
The fan is internally isolated. Fans available are
double-width, double-inlet Centrifugal types with
forward curved, backward inclined, or airfoil blade
type design; single-width, single-inlet Plug Fans or
Vane-Axial Q Fans
®
. Fans are available in low,
medium, and high pressure classes with or without
inlet guide vanes.
To insure fan stability, the unit ships with four (4) lock-
down devices that prevent the fan from shifting
during shipment and installation. These spacers
must be removed prior to fan operation to assure
proper vibration isolation.
The units are available with factory-mounted controls
for stand-alone operation or operation with a
complete building automation system. This includes
factory-mounted starters, DDC controllers, and end
devices.
Trane T-Series Climate Changers ship as complete
assemblies or sectional subassemblies. Some
assembly is required when the units ship as
subassemblies.
Operating Environment
The T-Series Climate Changer (TSC) is an outdoor
air handler. When considering the placement of the
TSC it is important to consider the operating
environment. The acceptable ambient temperature
range for unit operation is -40
°
to +140
°
F (-40
°
C to
60
°
C).
For heating applications a special motor may be
required to withstand the higher temperatures.
Motors with Class “B” insulation are acceptable for
ambient temperatures up to 104
°F while motors with
class “F” insulation can withstand ambient
temperatures to +140
° F (60
°
C).
NOTE: IT IS RECOMMENDED THAT THE CUSTOMER
PROVIDE ADEQUATE FREEZE PROTECTION FOR THE
COILS.
UNITS WITH UL APPROVAL HAVE A MAXIMUM
AMBIENT TEMPERATURE REQUIREMENT OF 104
°
F.
