Structure
The master module can work independently or together with
up to 15 slave modules, cooling capacity from 60 to 2048kW
Hermetic compressor
3-phase scroll type compressor, with built-in thermal overload
cut-out and crankcase heater, mounted on rubber vibration
dampers
Axial fan
External rotor type axial fans, equipped with three phase
direct drive motors, low noise 8 poles, protection level IP54,
provided with a protective outlet grille
Evaporator
Evaporator built with high efficiency tube in tube type heat
exchanger, factory insulated with flexible close cell material
Condenser
