Features and
Benefits
Condensing Units Options
The TWA075A and 100A single
compressor models feature single
refrigeration circuitry, lowering job
installation costs by requiring only one
set of refrigerant lines. These units are
ideal for the low cost, new construction
jobs as well as renovation and
replacement buildings.
In addition, Odyssey includes TWA155B
and 200B dual compressor units to give
true stand-by protection; if one
compressor fails, the second will
automatically start-up. Also, the first
compressor can be serviced without
shutting down the unit since the
refrigerant circuits are independent.
Dual compressors are not just for
protection, they also save energy costs.
Most buildings are designed for the peak
load requirements yet the building
usually operates at less than peak load.
During light load conditions, only one
compressor functions to maintain the
space comfort thus reducing the need
for energy.
Trane split systems have been specified
in thousands of applications and you’ll
find Odyssey will win you even more
jobs with its small manageable cabinet.
This light, compact design will save time
and money for rigging and installation.
And the compactness will permit Trane’s
unit to replace almost any unit —
effortlessly.
Low Ambient Cooling Operation
Each heat pump unit can operate to 50°F
(10°C) as standard in the cooling mode.
An accessory Head Pressure Control
gives you the capability to operate to 0°F
(-18°C). All heat pumps offer these
accessories:
Head Pressure Control
Coil Guard Kits
Isolators both Rubber-in-Shear and
Spring Type
Anti-Short-Cycle Kit
Time Delay Relay
Air Handlers Offer More
Flexibility
Flexibility is a key to meeting changing
market requirements. Odyssey split
sytems offer not only heat pumps but
also convertible air handlers. The air
handlers can be installed either vertically
in a mechanical room or horizontally
above a ceiling. And it doesn’t require
any removal of panels to make either
airflow application work. These air
handlers have a double sloped
condensate drain pan that allows for
either airflow configuration. And the
drain pan can easily be removed for
cleaning. All the air handlers feature
factory installed belt drive and ball
bearing evaporator fans with adjustable
sheaves for maximum airflow
performance. In fact, the standard motor
on the TWA100A air handler will deliver
3325 cfm (5649 m
3
/hr) at 1.4" (349 Pa)
ESP. Plus oversized motors are available
for higher static applications.
