TECHNICAL FEATURES FOR STANDARD VERSION (1):
Structure
With supporting frame, in peraluman and galvanized sheet. Stainless-steel screws.
Compressor
Scroll ermetic 1-phase (48÷74) or 3-phase (87÷420) compressor, complete with overload protection (klixon) embedded in the motor and crankcase, if needed, installed on rubber vibrations absorbing.
Fans
Axial fan type low ventilation and special wing profile, they are directly coupled to external rotor motors with protection grade IP54, and a safety fan guard fitted on discharge air flow.
Condenser
Copper tubes and aluminium finned coil.
Evaporator
In AISI 316 stainless steel braze welded plates type. The evaporator is insulated with flexible closed cells material. On the heat pump units is always installed an antifreeze heater.
Electrical panel
Includes: main switch with door lock device, fuses, compressor and pump remote control switch (108÷420).
Microprocessor controls the following functions:
regulation of the water temperature, antifreeze protection, compressor timing, alarm reset, potential free contact for remote general alarm, local or remote cooling / heating changeover (operating in heat pump), visual system with digital display: running cycle (cooling or heating), compressor delay relay/on, inlet water temperature, set point and differential setting, alarm decodification.
