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. 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?

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.

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.

As the cold stream enters the electrical cabinet, the hot air within the cabinet starts to rise and is gradually 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. 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. 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. 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. 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.
