Daikin EWAD830C-SS [93/96] Technical specifications

General

The chiller will be designed and manufactured in accordance with the following European directives:

• Construction of pressure vessel 97/23/EC (PED)

To avoid any losses, the unit will be tested at full load in the factory (at the nominal working conditions and water tempera

chiller will be delivered to the

comply with the manufacturer’s instructions for rigging and handling equipment.

The unit will be able to start up and operate (as standard) at full load with:

- outside air temperature from ............... °C to ............... °C

• Heat exchanger water flow : ............... l/s

• Nominal outside working ambient temperature in cooling mode : ............... °C

Operating voltage range should be 400V ±10%, 3ph, 50Hz, voltage unbalance maximum 3%, without neutral conductor and shall onl

have one power connection point.

Unit description

components, discharge line shut-off valve, control system and all components necessary for a safe and stable unit operation.

The chiller will be factory assembled on a robust base frame made of galvanized steel, protected by an epoxy paint.

Sound level and vibrations

………dB(A). The sound pressure levels must be rated in accordance to ISO 3744 (other types of rating can not be used).

Vibration on the base frame should not exceed 2 mm/s.

Dimensions

Unit dimensions shall not exceed following indications:
