TECHNICAL FEATURES FOR STANDARD VERSION:

Structure

With supporting frame, in peraluman, galvanized sheet and with rubber shock absorbers on the frame. Stainless-steel screws.

Compressor

Rotary 1-phase (46÷71), 1-phase Scroll ermetic com-pressor (84) and 3-phase Scroll ermetic compressor (101÷175), com-plete 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 IP 44, and a safety fan guard fitted on discharge air flow.

Condenser

Copper tubes and aluminium finned coil, complete with moisture drain pan in the heat pump version.

Evaporator

In AISI 316 stainless steel braze welded plates type, built-in the storage tank.

Electrical panel

Includes: main switch with door lock device, fuses, compressor contact and pump contact (101÷175).

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.
Electronic proportional device to decrease the sound level, with a continuous regulation of the fan speed. This device allows also the cooling functioning of the unit by external temperature till -20°C.
