The Polar Vortex is a rugged, highly specialized operator's cab air conditioning system that’s built to withstand the demands of round-the-clock use in harsh industrial settings, such as steel mills. The Polar Vortex makes use of components adapted from the heavy-duty trucking industry - every part of the air conditioner has been proven to hold up for millions of miles of on-road use. Polar Vortex was originally developed and proven through 4 years of testing on overhead cranes in some of America's largest steel mills.
