WARRANTY.

General Design

Trane TR-SCS series remote air-cooled condensers are
housed in an aluminum frame cabinet and are rated for
outdoor use. The figures that follow depict the two types
of condensers and identifies the major components.
Figure 1 depicts a layout of a typical TR-SCS condenser.
Figure 2 depicts a layout of a typical TR-SCS-MC
condenser.

Condenser Coil

The capacity of the condenser, indicated by the unit model
number, is based on the rated capacity of the coil. In the
case of dual circuit units, the model number is based on
the combined capacity of both coils.

TR-SCS Condenser Coils

TR-SCS condenser coils are copper tube, aluminum finned
coils.
TR-SCS-MC Micro-Channel Condenser
Coils
TR-SCS-MC condenser coils are brazed all-aluminum
construction with high performance fins which provide
improved airflow and higher heat transfer.

Fan Assembly

The condenser is equipped with high efficiency axial type,
impeller fan(s) rated for outdoor applications. The
quantity of fans vary depending upon the capacity of the
unit. The fan(s) use corrosion resistant, multi-blade
impellers designed for high aerodynamic efficiency which
results in lower power consumption, lower noise levels
and longer life. Each fan uses a direct driven motor with
maintenance free bearings. The fan motors are internally
protected from overload.
Electric Box
The electrical components are protected in a weather
resistant enclosure located at the header end of the unit.
The electric box has a removable front access panel which
is safety interlocked with the service disconnect switch,
preventing the panel from being removed when the switch
is in the "On" position. The switch must be turned "Off" to
gain access to the electrical components.

Receiver (Optional)

Receivers are furnished for air-cooled condensers using
flooded head pressure control for low ambient
temperature conditions. The optional receivers are
equipped with pressure relief valves and heater pads.
Receivers for TR-SCS condensers are mounted to a coated
steel base frame which may be attached to a suitable
foundation next to the condenser (see
head pressure control valve may be shipped loose for field
installation to the receiver if one is not already provided in
the indoor A/C unit.
The TR-SCS-MC condenser design differs in that receivers
are integrally mounted to the condenser frame (see
Figure 2). For -30°F applications a head pressure control
valve is factory installed and piped to the receiver.
