OPTIONS
Standard Options (supplied on basic unit)
Wye
-
Delta compressor starter (Y
-
-
For low inrush current and reduced starting torque
Double setpoint - Dual leaving water temperature setpoints.
Phase monitor
-
The phase monitor controls that phases sequence is correct and controls phase loss.
Evaporator victaulic kit
-
Hydraulic joint with gasket for an easy and quick water connection.
20mm evaporator insulation - The external shell is covered with a 20mm closed cell insulation material.
Evaporator electric heater
-
Electric heater (controlled by a thermostat) to protect the evaporator from freezing down to
-
28°C
ambient temperature, providing the power supply is on.
Electronic expansion valve
Discharge line shut-off valve - Installed on the discharge port of the compressor to facilitate maintenance operation.
Ambient outside temperature sensor and setpoint reset
Hour run meter
General fault contactor
Setpoint reset, Demand limit and Alarm from external device
-
(Set
-
point reset): The leaving water temperature set
-
point can be
overwritten with the following options: 4-20mA from external source (by user); outside ambient temperat
ure; evaporator water
temperature ∆t. - (Demand limit): User can limit the load of the unit by 4-20mA signal or by network system. -
(Alarm from external
device): Microprocessor is able to receive an alarm signal from an external device (eg. pump, etc…).
User can decide if this alarm signal
will stop or not the unit.
