Trane RTAA Refrigerator User Manual


 
RLC-PRC016-EN42
Options
Low Temperature Brine
The unit controls can be factory set to
handle low temperature brine
applications (0°F to 39°F).
Ice Making
The unit controls can be factory set to
handle ice making for thermal storage
applications.
Building Automation System
Communication Interface
Permits either bi-directional
communication to the Trane Integrated
Comfort
system or permits remote
chilled water setpoint and demand
limiting by accepting a 4-20 mA or 2-10
Vdc analog signal.
Remote Display
In addition to controlling chiller
operation from remote location, the
remote display shall provide the
capability to monitor unit alarms and
diagnostics. Only one twisted pair is
required between the chiller and the
remote display .
Remote Evaporator
The remote evaporator is available as a
standard option.
This option provides an easily installed,
pre-engineered method of installing the
evaporator remotely indoors.
The remote evaporator is skid-mounted
and is shipped separately from the
outdoor (condensing) unit. Refrigerant
accessories, including electronic
expansion valve, moisture indicating
sightglass and removable core filter
drier, are shipped with the evaporator
skid. All refrigerant connections are
routed to one end of the evaporator skid
for easy connection. All electrical wiring
is factory installed and routed to a
terminal box (entering and leaving water
temperature sensor, evaporator
refrigerant temperature sensor and
electronic expansion valve control
wiring). Suction refrigerant temperature
sensors (two) must be field installed in
the field suction line piping next to the
evaporator connections.
Chilled Water Reset
This option provides the control logic
and field installed sensors for either load
based (return water temperature) or
temperature based (ambient or zone)
reset of leaving chilled water
temperature (requires Communication
Package).
Architectural Louvered Panels
Louvered panels cover the complete
condensing coil and the service area
beneath the coils.
Coil Protection
Louvered panels which protect the
condenser coils only.
Access Protection
A coated wire mesh which covers access
area underneath the condenser coils.
Control Power Transformer
This option eliminates the need to run
separate 115 volt control power to the
unit. A control power transformer is
factory installed and wired. A separate
115 volt power source is required for
60 Hz heat tape.
Low Ambient Option
The low ambient option consists of a
variable speed drive on the first fan of
each circuit and special control logic to
permit low temperature operation.
Low Ambient Lockout
A factory installed ambient sensor and
control logic can prevent starting below
the recommended temperature.
Non-Fused Power Disconnect Switch
A non-fused disconnect switch with a
through the door handle is provided to
disconnect main power.
Circuit Breaker
A standard interrupting molded case
capacity circuit breaker (UL approved) is
available. The circuit breaker can also be
used to disconnect the chiller from main
power with a through the door handle
and comes pre-wired from the factory
with terminal block power connections.
Neoprene Isolators
Isolators provide isolation between
chiller and structure to help eliminate
frequency transmission. Neoprene
isolators are more effective and
recommended over spring isolators.
Spring Isolators
Spring isolators help isolate the chiller
from the building structure.
Condenser Corrosion Protection
Copper fins and CompleteCoat are
available on all size units for corrosion
protection. Job site conditions should be
matched with the appropriate condenser
fin materials to inhibit coil corrosion and
ensure extended equipment life. The
CompleteCoat option provides fully
assembled coils with a flexible dip and
bake epoxy coating.
Convenience Outlet
Provides a 15 amp, 115 volt (60 Hz)
convenience outlet on the unit.
