Outdoor unit for the production of chilled water with hermetic rotary scroll compressors, ozone-friendly refrigerant R410A, axial-flow fans, micro-channel full-aluminum condensing coils, internally designed and manufactured shell&tube heat exchanger, and electronic expansion valve. The range is composed of units equipped with four compressors in tandem configuration on two independent refrigeration 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
SHELL&TUBE HEAT EXCHANGER
The shell and tube exchanger provides the highest flexibility for the unit’s installation, keeping the pressure drops on the hydronic side at a minimum, thus representing the best choice for all the hydronic applications.
EXTREMELY SILENT OPERATION
The best compromise between silence and efficiency, as result of a systematic design oriented to minimize noise levels.
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.
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.
