General Description
OPTIONAL EXTRAS - ENERGY SAVING
Power Factor Correction When applied to the motors of each compressor, the compressor power factor is
controlled to a minimum operating value of 0.95 at the full operating capacity. This
satisfies many supply authorities that may impose surcharges on equipment with power
factor less than 0.95.
OPTIONAL EXTRAS - GENERAL - ALL MODELS
Epoxy Coated
Condenser Coils In atmospheres where high corrosion is anticipated epoxy coated aluminium finned coils
can be fitted.
Coil Guards Guards can be fitted to each of the outer coils to protect against damage.
Anti Vibration Mounts
(Spring Type)
Spring vibration isolators can be supplied loose for on site fitting to the base frame of
each condensing unit.
The isolators are suitable for fitting to a concrete slab or structural steelwork providing the
surface is level and of sufficient strength where a high level of vibration elimination
is required.
For further details, please refer to Anti Vibration Mounting section.
Anti Vibration Mounts
(Pad Type)
Pad vibration isolators can be supplied loose for on site fitting to the base frame of each
condensing unit.
The isolators are suitable for fitting to structural steelwork providing the surface is level
and of sufficient strength where a moderate degree of vibration elimination is required.
For further details, please refer to Anti Vibration Mounting section.
Condenser Fan
Discharge Air Plenum
Extension Constructed from galvanised sheet steel coated with epoxy baked powder paint, this
plenum directs discharge air vertically, thus limiting air re-circulation and provides a
degree of acoustic reduction in the horizontal plane, factory fitted. For details please
contact Airedale.
Standard unit colour is Light Grey (RAL 7035).
For further details refer to Dimensions .
Dual Pressure Relief
Valve A 3-way dual shut-off valve that incorporates 2 relief valves and rupture disc assemblies
per circuit. The valve allows the maintenance of individual pressure relief valves and
rupture discs without the need for refrigerant evacuation.
Discharge Line Ball
Valve To facilitate easier pump down to condenser coil, factory fitted.
Discharge Line non-
Return Valve To facilitate easier pump down to condenser coil, factory fitted.
Leak Detection Kit A factory calibrated and fitted leak detection kit, will raise an alarm when refrigerant gas
is detected.
Phase Rotation
Protection A phase sequence relay is available for units containing 3 phase scroll compressors, to
prevent possible damage by running the compressor in the wrong direction.
Liquid Receiver &
Pressure Relief Valve A liquid receiver, complete with rupture disc assembly, can be factory fitted. Sized to
accept the total refrigerant charge, including interconnecting pipework of an equivalent
length of 30m plus evaporator based on nominal conditions, for selection outside this
range, please contact Airedale.
