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.

What is the purpose of a Cabinet Cooler?

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.

The compressor air line connects to the cooler via a 1/4 NPT fitting.

The integrated vortex tube separates compressed air as it enters the cooler.

The hot stream from the vortex tube is exhausted into the atmosphere by passing through a muffler which ensures low noise levels.

The cold air enters the electrical cabinet though an outlet tube located at the bottom of the cooler.

The cold stream entering the electrical cabinet causes the hot air inside to rise, which is then 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. Supreme Air Products’ electrical panel coolers have been made of stainless steel for durability.

Specifications for Cabinet Coolers

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 crucial to seal off all openings and vents that could allow in ambient air, particularly in hot or humid environments. Cabinet Coolers that are continuously in operation maintain a relative humidity of 45%.

Filtration:

Clean filtered air should be used on all lines that power the Cabinet Cooler. We recommend a 5 micron auto drain filter. Proper filtration is imperative to prevent any accidental water flow into the enclosure. 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 (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.
