Our panel coolers for electrical cabinets are an easy, reliable and affordable way to cool or climatize any type of enclosures and panels. Supreme Air Electrical Panel Cooler uses compressed air to create hot and cold air streams. The coolers require only compressed air to work, so there is no need for harmful refrigerants and freon gas. They offer the ideal solution to cooling many types of enclosures and electrical cabinets with large cooling capacities up to 7200 BTUs.
How does a Cabinet Cooler work?
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.
The compressor air line connects to the cooler via a 1/4 NPT fitting.
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.
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.
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. Supreme Air Products’ electrical panel coolers have been made of stainless steel for durability.
Cabinet Cooler Specifications
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.
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%.
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.
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 (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.
