An insulated lorry uses a cold source other than mechanical compression or absorption equipment to lower and maintain its internal temperature. What specific cooling classification applies?

Correct answer

Refrigerated equipment with a non-mechanical cold source.

Refrigerated equipment with a non-mechanical cold source, such as ice or eutectic plates depending on design. Mechanically refrigerated equipment uses a refrigeration appliance such as compression or absorption equipment. Insulation remains necessary, but “insulated” alone does not specify the added cold source described.
