What is a Cabinet Cooler?


 
Our electrical cabinet panel coolers are a simple, reliable and inexpensive method to cool and climatize all types of electrical panels and enclosures. 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. 
 
 
 
 
 
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. 
Through an outlet tube at the bottom, cold air is drawn into the cabinet. 
The cold stream entering the electrical cabinet causes the hot air inside to rise, which is then 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 
 
Mounting: 
 
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. 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 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%. 
 
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. 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. Coolers are constructed of Stainless Steel (Type 304) to withstand harsh corrosive environments.
