Isotherm Truck

An isotherm truck is an enclosed vehicle with an insulated body designed to reduce temperature fluctuations during transport. Unlike a reefer, it focuses on maintaining a stable range rather than actively cooling to low setpoints (though some builds may include cooling equipment). Dimensions and payload vary by configuration and axle setup.

Use case: best for goods that require stable temperature protection without deep freezing—electronics, pharmaceuticals, chemicals, beverages, confectionery, and other cargo sensitive to heat/cold swings.
