4 - Component features
4.1 - Fan
Double section, galvanized steel, centrifugal fan, forward blades.
High efficiency.
The motor is single-phase; provided with internal thermal protec
tion.
The fan wheel is statically and dynamically balanced; the bearings
are self-lubricating.
4.2 - Compressor
SCROLL compressors
High COP (Coefficient Of Performance)
High MTBF (Minimum Time Between Failures)
Low sound level.
Vibration-damped.
Provided with internal thermal protection.
Low pickup current (equalization of the internal pressures).
4.3 - Coils
High front surface.
Made of copper pipes and aluminium fins.
Fins treated with hydrofile styrol acrylic paints to with
stand corrosive atmospheres.
Low pressure drop.
High SHR (Sensible Heat Ratio).
4.4 - Frame and panels
The sheet steel structure, painted with RAL 7035 epoxy-
polyester powders, is assembled by stainless steel screws;
the paneling system ensures higher stiffness; there will also
be some pluggings (compressor space and fan) for guaran
teeing both safety and high acoustic absorption.
The electric board protecting panel is assembled on hinges
to make the access easier; this can be opened by the fast
closing lock. The side panels are screwed to the supports.
The rear panel is screwed directly to the frame.
The air returns from the machine top in machines with un
derfloor air delivery, whereas in machines with upward air delivery it returns through the metal grid on the
front panel.
The compressor is housed in a closed space in the lower part of the unit and is completely insulated
against the air flow. The compressor section can be reached even during the unit operation by removing
the front panel and the protection plugging.
The panels are lined with thermoacoustic insulating material - class 1.
