SALES potential of refrigerator trucks seems to be several hundred new units annually, according to the authors. Motor-truck transportation of meat, milk, ice cream, fruits and farm produce demands refrigeration, as does delivery-truck transportation of butter, cheese, yeast and dough. Large trucks are needed for the former class and smaller ones for the latter, but the refrigeration problems are fundamentally the same.
Desirable body-construction is outlined and the different refrigerating systems are analyzed with regard to quantity of refrigeration needed, type of insulation and insulating material available. Mechanical systems are discussed under electric, power take-off and separate gasoline-engine drives for the compressor. The most desirable location for a refrigerating unit on a truck also is considered.
