TECHNICAL FEATURES FOR STANDARD VERSION (1):

Structure

With prepainted self-supporting frame, in galvanized sheet. Stainless-steel screws.

Compressor

Scroll-hermetic 1-phase (48÷74) or 3-phase (87÷341) compressor, complete with overload protection (klixon) embedded in the motor and crankcase, if needed, installed on rubber vibrations absorbing.

Fans

Double inlet centrifugal type statically and dynamically balanced directly driven by a single-phase (48÷87), three-phase (108÷177), belt driven connected to a three-phase electric motor (193÷341).

Condenser

Copper tubes and aluminium finned CON.

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 a antifreeze heater.

Electrical panel

Includes: main switch with door lock device, fuses, compressor and pump remote control switch (108÷341).

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.
