• Chillers • R-134A • EWWD-EJYNN

• Applied Systems • Chillers

4 Options

Standard Options (furnished on basic unit)

Heat Pump version (not for the EWLD-EJ)

Double set point

Brine double set point version (CB) - Dual leaving glycol mixture temperature setpoints. The lower setpoint can

go down to -8°C.

Compressor thermal overload relays - Safety devices against compressor motor overloading in addition to the

normal protection envisaged by the electrical windings.

Under/Over Voltage controller

Victaulic on condenser (not for the EWLD-EJ) - Hydraulic joint with gasket for an easy and quick connection.

Flow switch for evaporator

Rubber type anti-vibration mounts - positioned under the base of the unit for “floor” installation.

Set point reset, demand limit & alarm from external device

Star Delta Compressors starter – For low inrush current and reduced starting torque.

Phase monitor – The phase monitor controls the voltage values on the supply line stopping the unit when the

calibration threshold is reached (± 10%). This safety device is automatically reset.

General fault contactor – Contactor for the alarm warning.

Options (available on request)

100% total heat recovery (OPTR) – Produced with tube bundle placed in a single shell with the water

condensers. Heat exchangers heads are provided with 2 connections for entering/leaving heat recovery water and

2 separate connections for condensing water.

Partial heat recovery (OPPR) – Produced with plate to plate heat exchangers installed on discharge side of

compressor hot gas. These allow hot water to be produced up to a maximum temperature of + 50°C.

Ammeter and voltmeter (OP57) - Digital meters of unit drawn amperes and voltage values, installed on the

electrical control panel.

Condenser power factor correction (OPPF) - Installed on the electrical control panel to ensure it conforms to the

plant rules. (Daikin advices maximum 0,9).

Suction line shut off valve (OP12) – Suction shut-off valve installed on the suction port of the compressor to

facilitate maintenance operation.

Cu-Ni 90-10 exchangers (OPNI)– To work with sea water the heat exchangers are fitted with Cu-Ni tubes and

special protection inside the end covers.

Soft start (OPSS) –

Electronic starting device to reduce inrush current. An overload protection is included (no

need of compressors thermal relays).

Dual Pressure Relief Valve (OP03)

Liquid Receiver (OPLR) – available on EWLD-EJ only, the capacity is 170 Lt.
