Our electrical cabinet panel coolers are a simple, reliable and inexpensive method to cool and climatize all types of electrical panels and enclosures. 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. The cooler comes with a locking ring that locks it in 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. 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 be vertically mounted on a flat surface for all enclosure types. 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. We offer additional side mount kits for instances where coolers cannot be mounted on the top of the cabinet due to height restrictions.

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:

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. Coolers are constructed of Stainless Steel (Type 304) for longevity in wet environments.

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.
