The Best Way To Cool A Cabinet Or Enclosure

Supreme’s Electrical Cabinet Cooler ®

High-performance cooling for sensitive electronics in the harshest industrial environments. Our Stainless Steel construction provides ultimate protection against corrosion and washdowns while keeping your panels cool, dry, and dust-free.

Frequently Asked Questions

When installed correctly on a properly sealed NEMA-rated cabinet, Supreme Air Products enclosure coolers will not cause condensation. They operate by introducing dry, conditioned compressed air into the cabinet. This maintains a slight positive pressure inside the enclosure, which continuously purges warm air and actively prevents humid ambient air and moisture from entering.

CFM (Cubic Feet per Minute) measures the actual volume of air flowing under varying local conditions. SCFM (Standard Cubic Feet per Minute) measures the volume of air standardized to a specific set of conditions (typically 14.7 psia, 68°F, and 0% relative humidity). Using SCFM is critical because it allows you to accurately compare the air consumption and efficiency of pneumatic tools regardless of your facility’s local temperature and pressure fluctuations.

Static eliminators neutralize existing static charges on a material’s surface, but they cannot permanently immune the material from future charges. If your part undergoes further friction, separates from other materials, or is handled roughly after passing the ionizing bar or knife, a completely new static charge will be generated.
Standard compressed-air-driven air knives are engineered with extremely tight gaps designed for high-pressure systems (typically 60-100+ PSI). Blower systems operate on high volume but very low pressure (single-digit PSI). You cannot use our standard compressed air knives with a blower; they will not function.

Temperature limits depend primarily on the construction material. Supreme Air Products™ aluminum air knives generally withstand up to 250°F (121°C). Our stainless steel models can safely operate in severe environments up to 800°F (427°C), provided the appropriate high-temperature shims and hardware are utilized.
