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.

What is the purpose of a Cabinet Cooler?

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.

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

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.

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 be vertically mounted on a flat surface for all enclosure types. 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. 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 important to close off any openings and vents that may bring in ambient air, especially in warm, hot, or highly 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. If oil is present in the compressed air supply, use an oil filter with a minimum 0.3 micron rating.

Environment 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 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.
