Mack Model BM Truck Tractor with Attached Semi Trailer, 1933
Add to SetSummary
Mack Trucks introduced its Statotherm refrigeration system about 1933. It placed a refrigerant -- usually dry ice -- in a special compartment, while electric blowers controlled by a highly sensitive thermostat circulated cool air throughout the truck body. In a test run from Florida to New York, the Statotherm system kept a truck's interior at a near-constant 33 degrees Fahrenheit.
