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. The coolers require only compressed air to work, so there is no need for harmful refrigerants and freon gas. 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.
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.
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. Supreme Air Products' electrical panel coolers have been made of stainless steel for durability.
Cabinet Cooler Specifications
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.
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
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. If oil is present in the compressed air supply, use an oil filter with a minimum 0.3 micron rating.
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. 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.
