CHV/H/XE/MC 804-P÷2406-P
Very high efficiency air cooled liquid chillers with EC Inverter axial fans, Scroll compressors and plate exchanger
The very high efficiency liquid Chillers of the CHV/H/XE/MC 804-P÷2406-P series, with HFO-R1234ze refrigerant, are designed to satisfy the needs of medium and wide-sized service sector or industrial ambients.
They are used, combined with Fan Coil units, for the air conditioning of the rooms or to remove the heat developed during industrial processes.
Microchannel condensing coils on standard version provide higher efficiency levels (EER), as they ensure better heat exchange than conventional coils. Copper/aluminum coils are available on dedicated versions. Inverter control is available, as accessory, on circulating pumps for a further efficiency improvement.
The units are characterized by multi-compressor design on double cooling circuit, to reach high energy performances, reduction of current at start-up, elimination of inertial tanks and excellent silent functioning.
Are available as option the new EC Inverter fans with high available static pressure and efficiency. The units are compliant to the ErP Regulation.

Kenmerken
- Structure with supporting frame, made of galvanised sheet metal with additional protection provided by polyester powder coating.
- Scroll compressors with oil sight glass, internal overheat protection and crankcase heater.
- Axial fans directly coupled to an Inverter three-phase electric motor with external rotor. A safety fan guard is fitted on the flow discharge. The EC Inverter fans allow continuous and efficient operation of the unit with an outdoor air temperature as low as -20°C in cooling. They also allow to reduce the sound level, especially at night.
- Condenser made of aluminum MICROCHANNEL coils or copper tube and aluminum finned coils.
- Evaporator AISI 316 stainless steel braze welded plates type with two independent circuits on the refrigerant side and one on the water side, complete with water differential pressure switch.
- Cooling circuit shut-off valve on liquid line.
- Electronic expansion valve.
- Electronic high and low pressure gauges.
- HFO-R1234ze refrigerant.
- Electrical board includes: main switch with door safety interlock, fuses or magnetothermic switches, thermal protection relays for compressors and thermocontacts for fans.
- Microprocessor control and regulation system.
