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.
Supplementary heating can be offered to the control panel to ensure components such
as LCD displays operate in low ambients conditions.
Allows the chilled water setpoint to be adjusted via an external 0-10V signal.
A compressor mounted sump heater is available for low temperature applications.
Comprises:

Double regulating valve
Factory fitted to protect the evaporator from clogging by sediment and to enable the
system to be purged before running.
The regulating Flushing Bypass Kit additionally allows the chiller to run with a lower T
(typically for chilled beam and/or high water temperature applications).
Integral pumps may be fitted, standard or larger sizes selected to suit installed system
requirements. The following configurations are available:
Factory fitted with electrical switchgear and isolating valve.
Factory fitted dual pumps with filter ball valves on the inlet and outlet, the valves can be
maintained without interrupting chiller flow. Non-return valves are fitted to the outlet in
automatic changeover configuration. Supplied with electrical switchgear and
isolating valve.
The microprocessor can be programmed to automatically rotate usage of the run/standby
pumps to a set period.
