Daikin EWLD420I-SS [8/36] Options on request

Standard accessories (supplied on basic unit)

Evaporator Victaulic Kit - Hydraulic joint with gasket for an easy and quick water connection.

Evaporator Water side design pressure 10 bar

Y-D starter - Star Delta starter is the standard type

Double set-point - Dual leaving water temperature set-points.

Phase monitor - The phase monitor controls that phases sequence is correct and controls phase loss.

High Pressure Side Manometers

Hour Run meter - Digital compressors hour run meter

General fault contactor - Contactor for alarm warning.

Set-point reset, demand limit and alarm from external device – The leaving water temperature set-point can be

overwritten with the following options: 4-20mA from external source (by user); outside ambient temperature; evaporator

water temperature Δt. Moreover the device allow the user to limit the load of the unit by 4-20mA signal or by network system

and the 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).

Electronic Expansion Valve

Options (on request)

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

Liquid Receiver - the receiver capacity is 170 Lt

20mm Evaporator Insulation

Suction line shut off valve - Suction shut-off valve installed on the suction of the compressor to facilitate maintenance

operation.

Discharge line shut-off valves - Discharge shut-off valve installed on the discharge of the compressor to facilitate

maintenance operations.

Sound Proof System - Made of sheet metal and internally insulated, the cabinet is "integral kind" (around the whole chiller,

not only around the compressors) to reach the best performance in noise reduction.

Dual Pressure Relief Valve on evaporator

Soft start - Electronic starting device to reduce the mechanical stress during compressor start-up

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

protection envisaged by the electrical windings.

Under/Over Voltage – This device control the voltage value of power supply and stop the chiller if the value exceeds the

allowed operating limits.

Energy Meter – This device allows to measure the energy absorbed by the chiller during its life. It is installed inside the

control box mounted on a DIN rail and show on a digital display: Line-to-Line Voltage, Phase and Average Current, Active

and Reactive Power, Active Energy, Frequency.

Evaporator flow switch for the water piping

Rubber type antivibration mounts – Supplied separately, these are positioned under the base of the unit during

installation. Ideal to reduce the vibrations when the unit is floor mounted.

Witness test – Every unit is always tested at the test bench prior to the shipment. On request, a second test can be carried

out, at customer’s presence, in accordance with the procedures indicated on the test form. (Not available for units with glycol

mixtures).
