Compressor: High efficiency semi hermetic screw compressor with thermal protection through built-in compressor outlet line cut-off valve, and star delta starter.
6 capacity controls / 2 circuits which have a high energy efficiency at partial loads.
Evaporator: Shell & tube evaporator which is equipped with differential pressure switch, purging valve, built-in victaulic connection, cross flow, and rubber insulation, providing protection against UV-A rays.
Condenser: Copper pipe/aluminium fin condenser, consisting of two parts (gas and Freecooling circuits are separated from each other).
Water side 3 way modulation valve.
Fan: Electronically controlled axial fan which is equipped with built-in thermal protection and protection grill. and which ensures stable rotational speed at outdoor air temperature up to -15°C.
Control: Electronic microprocessor control for all BMS protocols (MODBUS RTU, LON, BacNet).
Carcass Structure: Powder polyester painted galvanized steel structure.
