General Description
OPTIONAL EXTRAS – GENERAL
Anti Vibration Mounts
(Spring Type)
Spring vibration isolators can be supplied loose for on site fitting to the base frame of
each chiller 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.
Anti Vibration Mounts
(Pad Type)
Pad vibration isolators can be supplied loose for on site fitting to the base frame of each
chiller unit.
The isolators are suitable for fitting to a structural steelwork only, providing the surface is
level and of sufficient strength where a moderate degree of vibration elimination is
required.
Sequence Control For the efficient temperature and capacity operation of multiple units on a single site, the
sequence controller will permit interlinked operation of the complete system thereby
providing optimum temperature control and minimum power consumption.
Included within this package is a site visit by Airedale Control Specialists to set up
multiple unit sequence control.
BMS Interface Card Enables Controlled chillers to be interfaced with most BMS, factory fitted,
please contact Airedale.
Dual Pressure Relief
Valve A 3-way dual shut-off valve that incorporates 2 relief valve 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.

the minimum full load current. Further benefits include removal of nuisance tripping,
supply voltage dips and motor overheating.
Leak Detection Kit
(DQ & DSQ Models Only)
A factory calibrated and fitted leak detection kit, will raise an alarm when refrigerant gas is
detected.
Flow Switch The flow switch will protect the chiller against low water flow, supplied loose.
Water Filter 20 mesh water filter(s) can be fitted on the inlet water pipework to protect the evaporator
from clogging by sediment, (supplied loose).
“Victaulic” Counterpipe
Kit A pair of grooved counterpipes and clamps for each heat exchanger can be supplied for
