4.6. Automatic defrosting
The cabinet is equipped with an automatic defrosting device. The NRC-100 unit controls the
operation periods and the defrosting process. Defrosting is performed three (3) times a day
(electric defrosting). Drain water from defrosting is automatically led to a hot gas evaporation tray
or to an electrically heated evaporation sump depending on the cabinet model. The temperature
inside the cabinet rises by a few degrees during defrosting.
