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?

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

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.

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. 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:

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.

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. Coolers are constructed of Stainless Steel (Type 304) to withstand harsh corrosive environments.
