TECHNICAL SPECIFICATIONS

70/73

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

directives:

• Construction of pressure vessel 2014/68/EU

• Machinery Directive 2006/42/EC

• Low Voltage 2014/35/EU

• Electromagnetic Compatibility 2014/30/EU

• Electrical & Safety codes EN 60204 –1 / EN 60335 -2-40

• Manufacturing Quality Standards UNI – UNI EN ISO 1400

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

and water temperatures). The chiller will be delivered to the job site completely assembled and charged

with refrigerant and oil. The installation of the chiller must 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

-evaporator leaving fluid temperature between ............... °C and ............... °C

Refrigerant

HFC 134a

Performance Chiller shall supply the following performances:

• Number of chiller(s) : ............... unit(s)

• Cooling capacity for single chiller : ............... kW

• Power input for single chiller in cooling mode : ............... kW

• Heat exchanger entering water temperature in cooling mode : ............... °C

• Heat exchanger leaving water temperature in cooling mode : ............... °C

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

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

• Minimum full load efficiency (EER): …………….. (kW/kW)

• Minimum part load efficiency (ESEER): …………….. (kW/kW)

Operating voltage range should be 400V ±10%, 3ph, 50Hz, voltage unbalance

maximum 3%, without neutral conductor and shall only have one power connection point.

Unit description Chiller shall include two independent refrigerant circuits, semi -hermetic type rotary

single screw compressors, electronic expansion device (EEXV), direct expansion ‘shell & tube’

evaporator, air-cooled condenser section made with aluminum Microchannel technology, R-134a

refrigerant, lubrication system, motor starting components, discharge line shut-off valve, control system

and all components necessary for a safe and stable unit operation.

Sound level and vibrations Sound power level shall not exceed ………dB(A). The sound power levels

must be rated in accordance to ISO 9614 (other types of rating cannot be used). Vibration on the base

frame should not exceed 2 mm/s.

Dimensions Unit dimensions shall not exceed following indications:

- Unit length ............... mm

-Unit width ............... mm

-Unit height ............... mm

Compressors The unit shall be equipped with:

• Semi -hermetic, single -screw type with one main helical rotor meshing with two diametrical opposed

gate rotors. The gate rotor will be constructed of a carbon impregnated engineered composite material.

The gate rotor supports will be constructed of cast iron. Electrical motor shall be 2-pole, semi -hermetic,
