Vortex enclosure & cabinet coolers
IP-66


general characteristics:

Totally maintenance-free enclosure & cabinet cooling devices with no moving parts.
Made of AISI 304 stainless steel. Operated by clean, dry compressed air.

how do vortex tubes work?

A Vortex Tube is a device with no moving parts that will convert any stream of compressed air into two streams – one hot and one cold.

A Vortex tube can produce cold air down to -35C and hot air up to +127C.

Clean, dry compressed air is injected tangentially into the tube at sonic speed and creates a cyclone (Vortex) spinning at about one million revolutions per minute.
Part of the air is forced to spin inward to the centre hole and travels up the long tube where a valve turns this spinning column (Vortex) of air inside itself.
The inside column of air gives up its heat to the outside column.
The cold air is then directed out the cold end of the Vortex Tube.
The temperature and air flow are totally controllable by adjusting the valve at the hot end of the tube.

NSYCAG38LP vents

In order for the vortex tube to work efficiently, the enclosure needs to be vented to allow through-flow
of air.
This can be achieved by fitting vents or louvres on the enclosure
