Unit description
This series of air-water chillers and heat pumps satisfies the
cooling and heating requirements of residential plants of small
and medium size.
All the units are suitable for outdoor installation and can be
applied to fan coil plants, radiant floor plants and high efficiency
radiators plants.
The refrigerant circuit, contained in a compartment protected
from the air flow to simplify the maintenance operations,
is equipped with rotary or scroll compressor (according to
the model) mounted on damper supports, brazed plate heat
exchanger, thermostatic expansion valve, reverse cycle valve,
axial fans with safety protection grilles, finned coil made
of copper pipes and aluminium louvered fins. The circuit is
protected by high and low pressure switches and differential
pressure switch on the plate heat exchanger.
The plate heat exchanger and all the hydraulic pipes are
thermally insulated in order to avoid condensate generation
and to reduce thermal losses.
All the units are equipped with variable speed fans control that
allows the units to operate with low outdoor temperatures in
cooling and high outdoor temperature in heating and permits to
reduce noise emissions in such operating conditions.
All three-phase power supply 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 and hydraulic connections are required
for installation.
