What is a Cabinet Cooler?




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. 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.




How does a Cabinet Cooler work?

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.

A compressed air line hooks up to the cooler by threading a 1/4 NPT fitting to the air inlet.
The integrated vortex tube separates compressed air as it enters the cooler.
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 coolers outlet tube and allows users to direct the cold stream to hot spots in the cabinet. All Supreme Air Products electrical panel coolers are made from stainless steel, which ensures durability.

Cabinet Cooler Specifications

Mounting:

Supreme Air Products(tm) Cabinet Cooler must be vertically mounted on a flat surface for all enclosure types. 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. 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:

Clean filtered air should be used on all lines that power the Cabinet Cooler. 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 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. Coolers are constructed of Stainless Steel (Type 304) to withstand harsh corrosive environments.
