What is a Cabinet Cooler?



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. Our coolers only require compressed air to operate, which eliminates the need for dangerous refrigerants or freon gases. With large cooling capacities of up to 7200 BTUs, they provide the perfect solution for quick and effective cooling in numerous types of electrical cabinets and enclosures.





What is the purpose of a Cabinet Cooler?

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.

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.
The cold air enters the electrical cabinet though an outlet tube located at the bottom of the cooler.
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:

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 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.
