Technical Specifi cation for Water Cooled Screw Chiller
GENERAL
The water cooled screw chiller will be designed and manufactured in accordance with following European directives:
Construction of pressure vessel 97/23/EC (PED)
Machinery Directive 2006/42/EC
Low Voltage 2006/95/EC
Electromagnetic Compatibility 2004/108/EC
Electrical & Safety codes EN 60204–1 / EN 60335-2-40
Manufacturing Quality Stds UNI – EN ISO 9001:2004
The unit will be tested at full load in the factory at the nominal working conditions and water temperatures. Before shipment a
full test will be held to avoid any losses.
Chiller will be delivered to the job site completely assembled and charged with right refrigerant and oil quantity.
Comply with the manufacturer instructions for rigging and handling equipment.
The unit will be able to start up and operate as standard at full load and condenser entering fl uid temperature from .… °C to
.… °C with an evaporator leaving fl uid temperature between …. °C and …. °C.
All units published performances have to be certifi ed by Eurovent.
REFRIGERANT
Only R-134a will be accepted.
