GENERAL FEATURES
Unit description
This series of packaged air conditioners and heat pumps
(roof top) satisfies the cooling and heating requirements of
medium and large buildings (commercial centres, ipermarkets,
cinemas, outlets, offices, canteens, restaurants ...)
All the units are suitable for outdoor installation and can be
applied to plants realized with various type of air ducts.
Each model is available in various constructive configurations
and can be equipped with a large range of accessories in order
to fit the different installation requirements.
The region in contact with the treated air, easily accessible,
is realized with perfectly washable metal surfaces, externally
insulated in order to minimize the thermal losses and to avoid
condensate generation both on the internal part and the
external part of the structure.
The refrigerant circuit, contained in a compartment protected by
the air flow to simplify the maintenance operations, is equipped
with scroll compressors mounted on damper supports. Each
compressor is placed on an independent refrigerant circuit in
order to keep a constant ratio between the sensible cooling
power and total cooling power also at partial loads and to
guarantee a better treatment of the air besides a greater
reliability.
Each refrigerant circuit is equipped with thermostatic expansion
valves, reverse cycle valve, axial fans with safety protection
grilles, finned coils made of copper pipes and aluminium
louvered fins and high and low pressure switches.
All the units are provided with a phase presence and correct
sequence controller device.
All the units are accurately built and individually tested in the
factory. Only electric, aeraulic and hydraulic connections are
required for installation.
