What is a Cabinet Cooler?
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?
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. Supreme Air Products' electrical panel coolers have been made of stainless steel for durability.
Specifications for Cabinet Coolers
Mounting:
Supreme Air Products(tm) Cabinet Cooler must be vertically mounted on a flat surface for all enclosure types. 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. For those coolers that cannot be mounted on top of cabinets due to height restrictions, we offer side mount kits.
Humidity:
It is crucial to seal off all openings and vents that could allow in ambient air, particularly in hot or humid environments. The relative humidity inside the enclosure stabilizes at 45% for all continuously operating Cabinet Coolers
Filtration:
Clean filtered air should be used on all lines that power the Cabinet Cooler. 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.
Environment Considerations
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. 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.
