enclosure & cabinet air conditioners (thermostat control)
IP-54


general characteristics

Main components: compressor, evaporator, condenser, control, cooling gas.
Thermostat controlled: the temperature required in the enclosure can be adjusted within a range of + 20 C to + 50 C.
As standard, the units are fitted with an automatic reset pressure switch. A value higher than safety pressure value (on the high pressure circuit) actuates compressor and external fan switch-off.
Operation of this safety device is by closing of a potential-free contact which can be used to operate an alarm light or siren connected to a programmable controller input.
Internal and external air circuits are totally separate (IP 54).
Two fans assure circulation of air in each of the circuits.
The internal circuit fan operates continuously avoiding the formation of hot spots in the enclosure.
Units are supplied with a drilling template, installation instructions and a sealing gasket.
A condensation drain tube is supplied with top mounting units.

usage conditions

Can be used at ambient temperatures of up to 55 C.
The filters used in cooling units should be regularly cleaned and replaced.
The enclosure should be sealed to avoid risks of condensation.
Ensure that the cooling unit switches off when the enclosure door is opened using a door switch.
