All Cool USA Technologies provides evaporative-cooling solutions, using novel, direct thermodynamic cooling technology. We advance human performance and mitigate the root cause of heat-related injury and deaths in all novice, amateur or professional persons undertaking outfitted activities in medicine, sports, the occupations, the military and first responders to emergencies and disasters.
On December 3, 1911, Willis Carrier presented the most significant and epochal document ever prepared on air conditioning – his "Rational Psychrometric Formulae" – at the annual meeting of the American Society of Mechanical Engineers. It became known as the "Magna Carta of Psychrometrics." This document tied together the concepts of relative humidity, absolute humidity, and dew-point temperature, thus making it possible to design air-conditioning systems to precisely fit the requirements at hand.
All Cool USA was formed to develop and design personal cooling solutions for the 21st Century in a way that Carrier created air-conditioning for the 20th Century.
