Outdoor unit for the production of chilled water with hermetic rotary Scroll compressors, ozone-friendly refrigerant R454B, axial-flow fans, micro-channel full-aluminum condensing coils, braze-welded plate heat exchanger and electronic expansion valve. The range is composed of units equipped with four compressors in tandem configuration on twoindependentrefrigeration circuits.
Hydronic module with 1 or 2 pumps, high or low head. Buffer tank available.
Set-up for remote connectivity with protocols: ModBus, ModBus over IP (TCP/IP), Echelon, BacNet MS/TP RS485, Bacnet over IP, Konnex, SNMP
Night mode to limit the maximum noise level of the unit.
Automatic circuit breakers on loads
Compressor power factor correction
ALUMINIUM MICRO-CHANNEL HEAT EXCHANGERS
The full aluminium micro-channel condenser coils deliver high efficiency while ensuring a reduced refrigerant volume and a lower unit weight. The e-coating protection (optional) grants the highest level of corrosion resistance in any condition, even in the most aggressive environments.
WIDE OPERATING RANGE
Full load operation is ensured with outdoor air temperature from -20°C up to 48°C (up to 52°C at partial load). Production of evaporator leaving water temperature from -12°C to 20°C.
EXTREMELY SILENT OPERATION
The best compromise between silence and efficiency, as result of a systematic design oriented to minimize noise levels.
INTEGRATED HYDRONIC MODULE
The built-in hydronic module already contains the main water circuit components; it is available as option with single or twin in-line pump, for achieving low or high head, fixed or variable speed and buffer tank.
ELECTRONIC EXPANSION VALVE SUPPLIED STANDARD
The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and at different working conditions. It guarantees energy savings due to efficiency optimization in various different working conditions which translates into a reduction in operating consumption, a faster start-up of the unit and a wider extension of the operating limits.
