General Description
Optional Extras
Anti Vibration Mounts
(Spring Type)
Spring vibration isolators can be supplied loose for on site fitting to the base frame of
each unit.
The isolators are suitable for fitting to structural steelwork providing the surface is level
and of sufficient strength where a high level of vibration elimination is required.
Anti Vibration Mounts
(Pad Type)
Pad vibration isolators can be supplied loose for on site fitting to the base frame of
each 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.
Discharge Air Plenum -
Condenser Fan Constructed from galvanised sheet steel coated with epoxy baked powder paint, this
plenum directs discharge air vertically, thus limiting a degree of air re-circulation and
provides acoustic reduction in the horizontal plane; factory fitted. For details please
contact Airedale.
Standard unit colour is Light Grey (RAL 7035).
Extended Discharge Air
Plenum - Condenser Fan Constructed from galvanised sheet steel coated with epoxy baked powder paint, this
plenum directs discharge air vertically, thus limiting greatly 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).
R134a Leak Detection
System A factory calibrated and fitted leak detection system, will raise an alarm when refrigerant
gas is detected.
Fitted within the unit compressor enclosure.
Closed Transition Star /
Delta Compressor Start Closed transition Star/Delta starting can be incorporated to avoid high transient
changeover current peaks when the compressor motor is switched over from Star to
Delta.
Flow Switch Will protect the chiller against low water flow conditions.
Despatched loose for on site fitment. (A 1 ” BSP socket is required in your pipework)
Pump Interlock A pump interlock shall be fitted to ensure that the chiller cannot operate without water
flow.
IMPORTANT IMPORTANT: The flow switch and or pump interlock must be fitted to the unit as
well as the differential pressure switch. At least two forms of protection must be
used. Differential pressure switch plus either flow switch or pump interlock.
Remote Setpoint Adjust Allows the chilled water setpoint to be adjusted via an external 0-10V signal.
BMS Interface Card Enables controlled chillers to be interfaced with most BMS, including
Airedale’s own pCOWeb, factory fitted, please contact Airedale.
