On a hot summer day, Joe Numero, a manufacturer of sound equipment for movie theaters, along with three of his close friends, just completed an afternoon of golf. One of the men in the group received word that a truck he owned had broken down en route from South St. Paul to Chicago, and the entire load of fresh chickens had spoiled. Another of the men suggested Numero build a mechanical refrigeration unit to replace blocks of ice currently used to cool semi-trailers. Numero, who liked challenges, responded on impulse by saying, “We can build a unit for you in 30 days.” This remark ultimately propelled Numero into becoming the founder and first president of U.S. Thermo Control, now known as Thermo King.
Joe Numero and engineer Fred Jones patent “Model A,” the first successful mechanical transport refrigeration unit. This introduces an alternative to the less effective use of salt and ice to preserve perishables during shipment, which ushers in the era of frozen foods, fresh produce delivery nationwide, large supermarkets and the restaurant industry.
The first nose mount trailer unit, the Model C, is introduced to the market. Compared to the previous under mount units, the Model C is much less susceptible to mud, dirt and debris and is also significantly lighter. It is the first one-piece design, which results in improved system reliability. The new, lightweight nose mounted model proves so successful it is named "Thermo King."
Thermo King develops the first portable refrigeration unit for troops overseas. During World War II, these portable units make a significant difference in the field, enabling soldiers to enjoy fresh foods, cold drinks, and most importantly, store temperature-sensitive drugs and blood plasma.
The "Service School," opens at the company’s headquarters in Minneapolis, Minnesota. The school evolves over the years into the Thermo King Education Center, offering state-of-the-art training and certification for technicians from around the world. This allows Thermo King service technicians to stay current with the latest technology and provide the best service in the industry.
Thermo King introduces the first refrigerated boxcar unit, the RY. Before the use of this new mechanical refrigeration system, shipping perishable products by rail was risky. Wooden rail boxcars with ice bunkers were manually loaded by workers with large ice blocks and then topped with crushed ice. The melting ice would ultimately cause the wooden floors to quickly rot, contaminating and spoiling the load. The new "Atmosphere Control" refrigerated rail cars were tested from 1948 to 1950, and during these two years, not one pound of cargo was lost from poor refrigeration.

Thermo King introduces the UWD, with the first diesel engine in refrigerated units, extending engine life compared to gas-powered units. Where a gas-powered engine had an expected life of 5,000 hours, a diesel-powered engine could run up to 25,000 hours. This allows for greater savings in engine maintenance and replacement and progresses the long-haul trucking industry.
