What is a Cabinet Cooler?

Our panel coolers for electrical cabinets are an easy, reliable and affordable way to cool or climatize any type of enclosures and panels. The Supreme Air Electrical Panel Cooler is an efficient pneumatic product designed to separate regular compressed air into hot and cold air streams. Our coolers only require compressed air to operate, which eliminates the need for dangerous refrigerants or freon gases. They offer the ideal solution to cooling many types of enclosures and electrical cabinets with large cooling capacities up to 7200 BTUs.
How does a Cabinet Cooler work?
Through a standard knockout hole, the cooler is mounted vertically to the top of a cabinet. A locking ring provided with the cooler locks it into place.
A compressed air line hooks up to the cooler by threading a 1/4 NPT fitting to the air inlet.
As compressed air enters the cooler, the integrated vortex tube separates the air into hot and cold air streams.
The vortex tube's hot steam is emitted into the atmosphere through a muffler, which produces low levels of noise.
The cold air enters the electrical cabinet though an outlet tube located at the bottom of the cooler.
As the cold stream enters the electrical cabinet, the hot air within the cabinet starts to rise and is gradually purged through the cooler.
An optional cold air distribution kit is also available. This connects to the cooler’s outlet tube and allows users to direct the cold stream to hot spots in the cabinet. All Supreme Air Products electrical panel coolers are made from stainless steel, which ensures durability.

Specifications for Cabinet Coolers
Mounting:
Supreme Air Products(tm), Cabinet Cooler must always be mounted vertically on a flat surface. A 1-1/8" diameter hole or electrical knockout can be used to mount an electrical cabinet cooler unit. The locking ring holds it in place. For those coolers that cannot be mounted on top of cabinets due to height restrictions, we offer side mount kits.
Humidity:
It is important to close off any openings and vents that may bring in ambient air, especially in warm, hot, or highly humid environments. The relative humidity inside the enclosure stabilizes at 45% for all continuously operating Cabinet Coolers
Filtration:
Clean filtered air should be used on all lines that power the Cabinet Cooler. We recommend a 5 micron auto drain filter. To prevent accidental water from entering the enclosure, it is important to filter properly. If oil is present in the compressed air supply, use an oil filter with a minimum 0.3 micron rating.
Environmental Considerations
NEMA 4/4X IP56 - Designed to be used in Electrical Control Panels. It is splash-resistant, oil-tight and dust-proof, making it suitable for outdoor as well as indoor use. For long-lasting use in wet environments, coolers are made of Type 304 Stainless Steel.
NEMA 12 (IP52 - Cabinet Coolers are oil-tight and dust-proof. They can be used in environments that allow liquids to not come into direct contact with the unit. To withstand extreme corrosive environments, coolers are made of Type 304 Stainless Steel.
