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.

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.

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 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.

We also offer an optional cold air distribution kit which connects to the cooler’s outlet tube and allows the user to direct the cold stream to specific hot spots within 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 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. For those coolers that cannot be mounted on top of cabinets due to height restrictions, we offer side mount kits.

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. The relative humidity inside the enclosure stabilizes at 45% for all continuously operating Cabinet Coolers

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 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. To withstand extreme corrosive environments, coolers are made of Type 304 Stainless Steel.
