    Our electrical cabinet panel coolers are a simple, reliable and inexpensive method to cool and climatize all types of electrical panels and enclosures. 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. 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?

    Through a standard knockout hole, the cooler is mounted vertically to the top of a cabinet. 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.

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

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