Our panel coolers for electrical cabinets are an easy, reliable and affordable way to cool or climatize any type of enclosures and panels. Supreme Air Electrical Panel Cooler uses compressed air to create hot and cold air streams. The coolers require only compressed air to work, so there is no need for harmful refrigerants and freon gas. 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?

The cooler mounts vertically on top of the cabinet through a standard knockout hole. 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.

We also offer an optional cold air distribution kit which connects to the cooler’s outlet tube and allows the user to direct the cold stream to specific hot spots within the cabinet. Supreme Air Products’ electrical panel coolers have been made of stainless steel for durability.

Cabinet Cooler Specifications

Mounting:

Supreme Air Products(tm), Cabinet Cooler must always be mounted vertically on a flat surface. An electrical cabinet cooler unit is easy to install through a 1-1/8” diameter drilled hole or an electrical knockout and is held in place by a locking ring. 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:

All lines that supply power to the Cabinet Cooler should be run through clean, filtered air. We recommend a 5 micron auto drain filter. Proper filtration is imperative to prevent any accidental water flow into the enclosure. Use an oil filter that has a minimum of 0.3 micron rating if oil is found in compressed air.

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 (oil-tight, dust-proof) are used in industrial environments where no liquids can come into contact with the unit. To withstand extreme corrosive environments, coolers are made of Type 304 Stainless Steel.
