1. OPTIONS AS STANDARD (1/2)
ALARM FROM EXTERNAL DEVICE – Microprocessor is able to receive an alarm signal from an external device (pump etc…). User can decide if this alarm signal will stop or not the unit.
FLOW SWITCH – Supplied separately to be wired and installed on the evaporator water piping (by others).
COMPRESSOR THERMAL OVER RELAYS – Safety devices against compressor motor overloading in addition to the normal protection envisaged by the electrical windings.
28Apr 21, 2023
UNDER/OVER VOLTAGE CONTROLLER – Phase monitor to control the minimum and maximum voltage value that the user can set.
RUBBER TYPE ANTIVIBRATION MOUNTS – Supplied separately, these are positionned under the base of the unit for “floor installation”.
ALUCOAT CONDENSER COILS – Fins are protected by a special acrylic paint with a high resistance to corrosion.
EVAPORATOR ELECTRIC HEATER – Electric heater controlled by a thermostat to protect the evaporator from freezing down -28°C ambient temperature.
ELECTRONIC EXPANSION VALVE – It proposes features that makes it unique:
short openning and closing time, high resolution, positive shut-off function to
eliminate use of additional solenoid valve, highly linear flow capacity,
continous modulation of mass flow without stress in the refrigerant circuit and
corrosion resistance stainless steel body.
