Daikin EWAD465TZ-SS [7/75] Options

OPTIONS

Standard Options (supplied on basic unit)

Double setpoint - Dual leaving water temperature setpoints.

Compressor thermal overload relays - Safety electronic devices that, added to the standard protection devices, protect

compressor motors against overload and current unbalance.

Phase monitor - Device that monitors input voltage and stops the chiller in case of phase loss or wrong phase sequence.

Inverter compressor starter

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.

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 (standard for single circuit

units only)

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.

Suction line shut-off valve - Installed on the suction 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 - 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.

Fans circuit breakers - Safety devices that, added to the standard protection devices, protect fan motors against overload and

overcurrent.

Main switch interlock door

Water filter - The water filter removes impurities from water by means of a fine physical barrier (available only on single circuit

units).

Options (on request)

MECHANICAL

Total heat recovery - Plate to plate heat exchangers for hot water production.

Partial heat recovery - Plate to plate heat exchangers for hot water production.

Evaporator flange kit Available only on dual circuits models (Shell&Tube)

Condenser coil guards

Cu-Cu condenser coil - To give better protection against corrosion by aggressive environments.

Cu-Cu-Sn condenser coil - To give better protection against corrosion in aggressive environments and by salty air.

Alucoat fins coil - Fins are protected by a special acrylic paint with a high resistance to corrosion.

Blygold Coil Treatment - It is a Polyurethane coating impregnated with metallic pigment which provides a long lasting corrosion

protection to condenser fins coils; it is UV resistant, flexible, heat conductive, chemical resistant to aggressive environments.

High pressure side manometers

Low pressure side manometers

Double pressure relief valve with diverter

Evaporator right water connections Available only for dual circuit units.

Brine version - Allows the unit to operate down to -8°C leaving liquid temperature (antifreeze required). Reccomended below +4°C
