	Data declared according to EN 14511. The values are referred to units without options and accessories.
	EER (Energy Efficiency Ratio) = ratio of the total cooling capacity to the effective power input of the unit
	COP (Coefficient Of Performance) = ratio of the total heating capacity to the effective power input of the unit
	ESEER (European Seasonal Energy Efficiency Ratio)
	Unit in A CLASS.
	W30W7 = source : water in 30°C out 35°C / plant : water in 12°C out 7°C
	W10W45 = source : water in 10°C / plant : water in 40°C out 45°C

This new range of water-cooled water chillers are designed to meet the climate control and air conditioning needs of large capacity systems in the industrial, commercial sectors.
Compact and highly configurable units, they are built to adapt to the various types of system design and meet the requirements of highly qualified designers.
The arrangement of the main unit components ensures even distribution of the unit's weight and easy service access.
When developing the range special attention was paid to the choice of heat exchangers to obtain high efficiencies at full loads and partial loads to maximise the seasonal efficiency rating (ESEER) and therefore reduce consumption and running costs. The units can therefore by combined with liquid coolers (dry-coolers), cooling towers, geothermal boreholes or used for water cooling (e.g. water system, well, stratum).
All the units are carefully built in compliance with current regulations and individually tested.
Installation therefore only requires the electrical and hydraulic connections.

Cooling only unit (IR)

COMPRESSOR: TWIN-SCREW type, mounted on vibration-mounting rubber supports, with variable capacity from 25 to 100%.
REFRIGERANT CIRCUIT IR, complete with maximum and minimum pressure switch, PED safety valves, dehydrator filter, liquid/humidity indicator, compressor delivery and liquid shut-off valves, compressor oil heaters and electronic expansion valve complete with regulator located in the electrical panel.
SYSTEM SIDE EXCHANGER: high efficiency shell and tube type with grooved tubes, optimised for R134a, fitted inside a shell of thermal insulation material to prevent condensation and heat exchange with the outside, complete with water side differential pressure switch, insulation, Victaulic connections and antifreeze heater.
