Ultimate Assurance: 75 Years of Trusted Expertise, Innovation, Partnership and Performance

Past

By combining an engine, a compressor and a condenser to cool trucks, Thermo King founder Joseph Numero and chief engineer Frederick Jones patented the first successful mechanical refrigeration unit, the Model A, in 1938. That landmark invention introduced Thermo King as the ultimate refrigerated transport expert, ushering in the era of frozen foods, large supermarkets, the present-day restaurant industry – and the possibility of fresh food delivery anywhere, anytime – no matter what the season. 

In 1956, Thermo King used its temperature control knowledge and expertise to develop the first air conditioning unit for passenger buses. This breakthrough allowed patrons to travel in comfort even during the hottest months of the year.
