Isuzu refrigerated truck adopts sandwich-type compartment structure, with polyurethane insulation density of 45kg/m³, and with independent chiller to realize precise temperature control from -25℃ to 18℃. The aluminum alloy T-type air duct embedded in the bottom of the compartment ensures that the uniformity of cold air circulation reaches ±1℃. The patented design of quick-loading cold storage plate system can maintain low temperature for 8 hours after power failure, which is the preferred solution for pharmaceutical cold chain and high-end fresh food distribution, and the key indexes are in line with GDP/GSP certification standards.
