  • Page 9: General Description

    Operating and service manual General description units, models SCU-40 and SCI-40 are electric powered picture frames, cooling and heating units operating on refrigerant R134a. The unit is designed to maintain cargo temperatures in a range from –30°C (-22°F) to +30°C (86°F).

  • Page 10: Function Description

    Operating and service manual The unit is equipped with a dual system for defrosting. There is installed a hot gas valve, in the refrigeration system, for hot gas defrosting of the evaporator coil. Furthermore the heating elements, mounted under the evaporator coil, are energized during defrost. This dual system for defrosting ensures a fast defrost sequence and thereby only a very small input of heat to the container.
