To limit compressed air consumption, it is advisable to integrate a thermostat
and a solenoid valve in the cooling system.
Thermostat
If a thermostat (normally open contact: closes when the temperature rises) is
used, it should be installed in the warmest part (top of the control cabinet).
Solenoid valve
The supply air can be shut off with a normal closed 2/2 solenoid valve. This valve
is usually controlled by a thermostat, optionally by the machine control.
Continuous flushing (Purging) of the control cabinet: the solenoid valve is
provided with a minimum leakage flow - about 20 Nl / min. - This keeps the
control cabinet continuously in overpressure, and dust and moisture are kept
outside.
Malfunctions and maintenance
Vortex coolers are maintenance-free when installed correctly and using the
correct quality of compressed air. If no cold air is produced, the compressed air
inlet pressure should be checked.
Causes of an inlet pressure that is too low: clogged filters, pipe diameters that
are too small or other cross-sectional constrictions.
