During the conversion process, the internal cargo space was coated for slight freezing (up to -10º C), heavy shelves were built in and air-curtains were added to the doors by "BVPLAST" in order to minimize cooling loss during transportation. A new Thermoking cooling system (type: V-300 20MAX) was also installed. The cooling system control and the temperature recorder were placed inside the driver cabin, enabling easy operation and control while on the way.
