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. With large cooling capacities of up to 7200 BTUs, they provide the perfect solution for quick and effective cooling in numerous types of electrical cabinets and enclosures.

What is the purpose of a Cabinet Cooler?

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

Through an outlet tube at the bottom, cold air is drawn into the cabinet.

The cold stream entering the electrical cabinet causes the hot air inside to rise, which is then 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. 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 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. A 5 micron auto drain filter is recommended. 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 for Electrical Control Panels – Splash resistant, oil-tight, and dust-proof for use in wash down environments as well as outdoor use. Coolers are constructed of Stainless Steel (Type 304) for longevity in wet environments.

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.
