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. 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?

The cooler mounts vertically on top of the cabinet through a standard knockout hole. A locking ring provided with the cooler locks it into 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.

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 crucial to seal off all openings and vents that could allow in ambient air, particularly in hot or humid environments. The relative humidity inside the enclosure stabilizes at 45% for all continuously operating Cabinet Coolers

Filtration:

Clean filtered air should be used on all lines that power the Cabinet Cooler. We recommend a 5 micron auto drain filter. To prevent accidental water from entering the enclosure, it is important to filter properly. 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. Coolers are constructed of Stainless Steel (Type 304) to withstand harsh corrosive environments.
