Vortex Cabinet Coolers

Cooling with Compressed Air

link to cabinet cooler sizing guide

Vortex Cooler tm Enclosure Cooling Systems use vortex tubes to convert factory compressed air into cool, filtered air without refrigerants.

They operate quietly, maintain positive pressure and create no RF interference while effectively cooling confined electrical and electronic enclosures.

Applications:

• Control panels
  
  
• CNC's
  
  
• Robotic equipment
  
  

Today's compact, multi-function electronic controls, variable speed drives and servos are extremely sensitive to heat and contamination while their confined enclosures make temperature control difficult. Excessive heat causes components to cook, digital displays to misread, starters and breakers to trip below rated loads and controls to drift. Fans often provide inadequate cooling and commonly pull in dirty, humid air creating another source of failure. ITW Vortec's Vortex Cooler™ Enclosure Coolers are the low-maintenance alternative for keeping enclosures cool and clean -- without Freon or other refrigerants.	Figure 1. Vortex Cooling System
Features: Eliminate downtime caused by dirty, overheated controls. Replace hot, dirty air in the enclosure with cool, clean air. May be thermostatically-controlled to operate only when necessary to save energy. Use a vortex tube to generate cold air without Freon or other refrigerants (CFCs/HCFCs). Compact size, easy to install. Exceptionally reliable, no moving parts to break. Maintenance-free, no compressors or filters to clean. Maintain NEMA 4, 4X and 12 ratings. Cooling capacities up to 5000 BTUH (1250 kcal/H).	Prevent downtime from overheated, dirty controls with Vortex Coolers.
