One Condensing Unit
Section 3: Description of the Equipment
The compressors are managed by a dedicated inverter, which allows modulation of the capacity from 25
to 100%.
The compressor(s) can be include a bypass solenoid to facilitate starting. Each line includes a check valve.
The unit is equipped with pressure switches and safety valves to address any malfunctions.
In addition, there are: a high-pressure valve (HPV) in general delivery after the gas cooler, intermediate liquid and
gas separation receiver, a flash gas bypass to keep the pressure constant at the receiver itself (only in certain
configurations), a braze-weld liquid filter with relative indicator, a liquid-intake heat exchanger (if equipped),
insulation of all cold parts, shut-off valves, and service valves for easy maintenance.
An electric power panel with electromechanical switches and electronic control allows the power supply and
management of the entire gas cooler system and intercooler (if equipped).
The unit can communicate with the supervisory systems through Modbus RTU communication via RS485 and
can also be provided with a system of remote communication with the owner.
The compact design allows installation even in small spaces. The structure is made of bent sheet metal
with epoxy paint and suitable feet dampen the vibrations. Depending on the version, the equipment can
be soundproofed.
The equipment, depending on the model, has two different voltages: 230/1/60 Hz and 460/3/60Hz. For
refrigeration, electrical, management, and operating logics, refer to the appropriate documentation and manuals.
Regardless of the configuration, the equipment is always supplied without the air evaporators so it is not able to
perform the function for which it is created without the evaporating unit. To determine the desired refrigeration
cycle, the customer must install it in a complete refrigeration circuit .
The equipment is accessible via the two front panels (LH and RH front panels).
The RH front panel gives access to the electrical enclosure and compressor compartment. This panel is also
fitted with the master power switch. The RH side is the only side which can be accessed for installation and
maintenance when the machine is powered on.
The LH front panel is equipped with the fans. This panel gives access to the gas cooler compartment, and can
only be opened when the machine is powered off.
The layout is shown on the following page. For additional information, refer to the wiring diagram and
enclosed documentation.
