OPTIONS
Standard Options (supplied on basic unit)
Direct on line starter (DOL)
Double setpoint - Dual leaving water temperature setpoints.
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.
Electronic expansion valve
Options (on request)
General fault contactor
Hour run meter
Main switch interlock door
MECHANICAL
Heat Pump version reversing on water side
Evaporator and condenser victaulic kit- Hydraulic joint with gasket for an easy and quick water connection.
Water filter(*) - The water filter removes impurities from water by means of a fine physical barrier.
Evaporator and Condenser flow switch (**)
20mm condenser insulation - The external shell is covered with a 20mm closed cell insulation material.
Partial heat recovery - Plate to plate heat exchangers for hot water production.
Brine version - Allows the unit to operate down to -10°C leaving liquid temperature (antifreeze required). Recommended below
+4°C
Suction and discharge line shut-off valve - Installed on the suction and discharge ports of the compressor’s tandem to facilitate
maintenance operation.
High anfìd low pressure side manometers
Sound Proof System (Compressor jacket)
Sound Proof System (Compressor Enclosure)
One centrifugal pump (low lift– 100 kPa available static pressure) - Hydronic kit consists of: single direct driven centrifugal
pump, water filling system with pressure gauge, safety valve, drain valve. The motor pump is protected by a circuit breaker installed
in control panel. The kit is assembled and wired to the control panel.
One centrifugal pump (high lift– 200 kPa available static pressure) Hydronic kit consists of: single direct driven centrifugal
pump, water filling system with pressure gauge, safety valve, drain valve. The motor pump is protected by a circuit breaker installed
in control panel. The kit is assembled and wired to the control panel.
Double pressure relief valve with diverter
(*) the installation of the filter is mandatory.
(**) the installation of the flow switch is mandatory on evaporator side.
ELECTRICAL / CONTROL
Phase monitor - Device that monitors input voltage and stops the chiller in case of phase loss or wrong phase sequence.
Under / Over voltage control - Electronic device that monitors and displays input voltage, and stops the chiller in case of phase
loss, wrong phase sequence, or voltage exceeding minimum and maximum allowed values.
Energy meter - Device installed inside the control box that displays all chiller electrical power parameters at line input such as line
voltage and phase current, input active and reactive power, active and reactive energy. An integrated RS485 module allows a
Modbus communication to an external BMS.
Capacitors for power factor correction - Devices that increase the power factor of the unit. The capacitors are “dry” self-
regenerating type with over pressure disconnecting safety device insulated with a no toxic dielectric mix without PCB or PCT.
Setpoint reset, Demand limit and Alarm from external device - Setpoint Reset: The leaving water temperature set-point can
be overwritten with an external 4-20mA, through the ambient temperature, or through the evaporator water temperature ΔT.
Demand Limit: Chiller capacity can be limited through an external 4-20mA signal or via network. Alarm from external device: The
unit controller is able to receive an external alarm signal. The user can decide whether this alarm signal will stop the unit or not.
