GENERAL SAFETY INSTRUCTIONS
The coolers must be used only for their intended purpose; only approved coolants must be applied.
Any attempt to activate the product with no coolant gas is strictly forbidden.
Never start the cooler before all external panels have been closed in order to avoid the risk of
electrocution or contact with moving parts.
In case it is necessary to evacuate the coolant from the system, do not disperse it in the environment,
but collect it by means of special exchange units.
OPERATING PRINCIPLE
The cooler is purposed to
cool electrical enclosures. It
may be externally mounted
to an enclosure wall. It allows
air cooling and dehumidifying
inside the enclosure and
avoiding failures of electrical
and electronic components
installed therein. The cooler
is
provided
with
an
adjustable
intervention
thermostat.
The
cooling
circuit starts to function only
after the pre-set temperature
has been reached.
The principal components
constituting the circuit are:
evaporator,
condenser,
compressor and expansion
device.
The compressor compresses
the cooling fluid (R134a) at
high
pressure
and
temperature.
At the output of the compressor the cooling fluid in the state of overheated vapour is transferred to the
external exchange unit (condenser), where releases the heat to the external environment and condenses
completely.
