2 CONSTRUCTIVE FEATURES
VENTILATION SECTION
Statically and dynamically balanced centrifugal fans with forward-curving
blades, directly mounted on the electric motor. All electric fans are mounted
on an appropriate structure with interposed vibration dampers to reduce the
propagation of vibrations.
All units are equipped with phase-cut speed regulator controlled by the pressure
probe.
The ventilation compartment is completely insulated with anti-condensation
material and separated from the compressor/electrical system compartment
for inspection purposes when the unit is working (without interfering with the
finned block exchanger).
The absence of belt drive and the frontally removable fan considerably reduce
maintenance work.
FINNED BLOCK HEAT EXCHANGER
Built with 3/8" copper piping and aluminium fins.
The special engineering of the heat exchangers allows defrost cycles to be
carried out at maximum speed in the models with heat pump operation, which
brings clear benefits in terms of the integrated efficiency of the whole cycle.
The condenser coil can be fitted with a metal filter that is easily removed from
the machine side panels in case of ducted air intake.
With heat pumps, an aluminium condensate drip pan is mounted that can be
ducted. To prevent ice from forming, a heating cable is installed in the heat
exchanger base.
ELECTRIC PANEL
The electric panel is built and wired according to the CEE 73/23 directive, to
the 89/336 directive for the electromagnetic compatibility and related standards.
Built with steel panels sheet, completely closed and protected by the enclosing
panels of the unit.
It is composed by:
- compressors conctactors
- pump relay
- pump, fans, trasformer and main control box protection fuses
- 230V/24V tranformer
- terminal box
