Providing relief for your cabinets with vortex-tube-based coolers has advantages to combat today's heat-producing electronics and harsh conditions. Many - but not all - cabinet cooler systems are UL listed to maintain the existing NEMA integrity of your current enclosure.

If the coolers are not UL listed, there are no guarantees that your electronics will be protected from the surrounding environment.

NEMA 12 coolers are intended for indoor use primarily to provide a degree of protection against dust, falling dirt and dripping non-corrosive liquids. NEMA 4 coolers are intended for indoor or outdoor use primarily to protect against windblown dust and rain, splashing water and hose directed water. NEMA 4X enclosures offer the same protections as NEMA 4 with an added protection against corrosion by using corrosion-resistant stainless steel materials.

Maintaining these NEMA ratings requires little more than installation through the cabinet's existing knockout or cutting a hole if no knockout is available. CE approval, for users or OEM manufacturers with users overseas, can also be found on vortex tube coolers.
