Our panel coolers for electrical cabinets are an easy, reliable and affordable way to cool or climatize any type of enclosures and panels. 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. 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 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 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. 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:

All lines that supply power to the Cabinet Cooler should be run through clean, filtered air. A 5 micron auto drain filter is recommended. To prevent accidental water from entering the enclosure, it is important to filter properly. 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. 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.
