STRUCTURAL FEATURES
Load-bearing structure and panels in galvanised and RAL 9018
painted sheet metal; galvanised steel sheet metal base.
The structure consists of two sections:
• technical compartment that houses the compressors, electrical
panel and main components of the cooling circuit;
• aeraulic circuit to house the heat exchange coils and motor-driven fans

External rotor axial motor-driven fans equipped with internal
thermal protection and complete with a protection grille set in a sin-
gle row for 2-compressor units and in a double row for 4-compres-
sor units, (except for chiller models 4150÷4270 versions B and S).
The S-Silenced version has a standard proportional electronic
device (FI10) for pressurised and continuous adjustment of the fan
rotation speed up to outdoor air temperature of -10°C when operat-
ing as a chiller, and up to outdoor air temperature of 40°C when
operating as a heat pump.
The Q-Super silenced version has a standard electronic propor-
tional device (FI15) for pressurised and continuous adjustment of
the fan rotation speed, up to a minimum outdoor air temperature of
-15°C when operating as a chiller, and up to a maximum outdoor air
temperature of 40°C when operating as a heat pump.
Victaulic-type hydraulic connections.
Differential pressure switch that protect the unit from any water
