Panel & Camera Coolers Based on Vortex Tube Technology

KJN Enterprises, under license from Nex Flow Air Products Corp., Canada, has introduced Panel and Camera Coolers. These provide a low cost method of both purging and cooling electrical and electronic control panels and camera housings by using a stainless steel vortex tube to create cold air from ordinary compressed air. The units are maintenance free since there are no moving parts and extremely reliable because even on the hottest days, as long as there is storage of compressed air, they will not break down. There are no compressor motors to burn out, one of the biggest problems with more costly air conditioning systems. Even though the use of compressed air does add to energy use, the cost is more than offset by savings in maintenance and added reliability in many applications.
Advantages of the vortex cooling system:

• Compact
• Low in cost
• No CFCs
• Fast installation
• Stabilises enclosure temperature and humidity
• Virtually maintenance free (no moving parts)
• Mounts in a standard electrical knock-out
• Stops heat damage and nuisance tripping
• Eliminates fans and filters
• Prevents dirt contamination by keeping enclosure at positive pressure
• Units applicable to all environments including high temperature to 200ºF.
