	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
	C50W7 = condensing temperature (dew point) = 50 °C - subcooling = 5°C - plant : water in 12°C out 7°C
	C45W7 = condensing temperature (dew point) = 45 °C - subcooling = 5°C - plant : water in 12°C out 7°C

This new range of evaporating units is designed to meet the climate control and air conditioning needs of large capacity systems in the industrial, commercial sectors.
These units are suitable for indoor installation, very compact and highly configurable.
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 refrigeration components enables even distribution of the unit's weight and easy service access. When developing the range special attention has been 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 be combined with the remote condenser selected according to the characteristics.
All the units are carefully built in compliance with the current regulations and individually tested.
Installation therefore only requires the electrical and hydraulic connections.
cooling only units (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.
ELECTRICAL PANEL: for power and control complete with door lock main disconnecting switch, microprocessor controller with keyboard-display, and sequence meter (standard).
