Tender Specification SyScroll 20-30 Air EVO HP Tender Specification SERIES: SyScroll 20-30 Air EVO HP TYPE: Air to water inverter driven heat pump TECHNOLOGY: scroll compressor / inverter driven CAPACITY RANGE: Cooling 20-35 [kW] Heating 20-34 [kW]
Tender Specification SyScroll 20-30 Air EVO HP 1. General description SyScroll Air EVO air cooled water heat pumps have been designed and optimized to operate with R410A refrigerant and inverter driven scroll compressors. Thanks to inverter technology it is possible to cover with only 2 sizes a very wide capacity range both in cooling (from 20 to 35 [kW]) and heating (from 20 to 34 [kW]) operation. All units are equipped with a single inverter driven 3-phase scroll compressor.

Tender Specification SyScroll 20-30 Air EVO HP 3. Cabinet The cabinet is made of heavy gauge galvanized steel. All galvanized steel components are individually painted by a special painting process before the assembly of the unit. This painting system performs a homogeneous protection to the corrosion. The painting is a polyester powder based type, colored in RAL 7040. The units are suitable for outdoor installation, directly on the building roof or at the ground level. 4.
Tender Specification SyScroll 20-30 Air EVO HP They are protected by a 35 [W] antifreeze electric heater to ensure a good protection against freezing at low ambient temperature when the unit is switched off. Maximum working pressure is 10 [bar] at water side and 45 [bar] at refrigerant side. 6. Air cooled condenser coil Outdoor heat exchangers are finned tubes coils. Coils are built with internally grooved copper tubes expanded into corrugated aluminum fins.
Tender Specification SyScroll 20-30 Air EVO HP Refrigerant circuit is equipped with one hermetic scroll compressor, 4-way reversing valve, bi-flow filter drier, sight glass, bi-flow electronic expansion valve, liquid receiver and suction accumulator. 9. Hydraulic circuit All units are equipped with multi-stage centrifugal pump providing outdoor available static pressure. Pump impeller is insulated with anti-condensation shell. Water filter is supplied as standard.
