SAFETY DEVICES
During the design and construction phase, the Manufacturer has included safety devices (active and passive) in keeping with the current
legislation in the country of use. It is necessary to check, in particular, and on ordering the equipment, that the standard fittings or suppliable
options correspond to the requests and usage requirements. Below are the main safety devices installed on the machine.
SAFETY VALVES
Safety valves are installed on the gas circuit upstream and downstream of the compressor (C). Valve
“A”,
high-pressure side,
is always installed on the equipment, while valve
“B”
low pressure is only installed if required by the regulations of the
country of installation. The function of the valves is extremely important because in all abnormal working conditions, or
when there is a risk of damage to people or property, the device opens the opening, the refrigerant comes out of the circuit
and the pressure returns within the safety parameters. It is essential to ensure correct maintenance of the equipment to
allow the valves to be activated properly in the event of an emergency.

ACCESSORIES
There are various accessories for this equipment, which serve different purposes. To see a complete list of accessories, please refer to the
technical product catalogue, which can be requested from the Manufacturer and directly from the Company’s Sales Office
. This section only lists
the main accessories that substantially change
the machines’
configuration when installed.
ANTI-VIBRATION MOUNTS (Optional accessory)
There are two types of anti-vibration mounts: standard or anti-seismic. The choice obviously depends on the requirements and needs of the
place of installation. Anti-seismic mounts guarantee excellent performance also in places where earthquakes are frequent. The mounts are
supplied separately from the chiller, in assembly kits, since assembly in the factory could result in serious damage during loading/unloading and
transport, mainly due to the uncontrollability of the resulting oscillations. They must be connected to the machine during the installation phase,
immediately before set up.
