Inside the Vortex Cooler, a Vortex Tube spins the supplied compressed air, separating it into hot and cold airstreams.
The cold airstream is distributed throughout the enclosure via a ducting tube, while the hot side exits out the side of the Cooler body. The low pressure cold air flows into the cabinet forcing the heated internal air out a relief valve or vent built into the base of the Cooler. The slight positive pressure helps purge the cabinet of dust and dirt.
Thermostat controlled models utilize a solenoid valve to activate the compressed air flow to the unit.
