The MOBILUX 21 COMBI takes the same idea as the smaller 11 COMBI to 206 litres net: the chest runs on a rechargeable 12 V battery which, according to the manufacturer, lasts 8–13 hours on a full charge depending on conditions. That allows ice cream or other chilled goods to be sold away from a mains supply.
Two sliding lids open onto an aluminium interior with two wire baskets, and the chest can be locked. Cooling is static, defrosting is manual and a mechanical thermostat sets the temperature, with a thermometer for checking it. A rechargeable battery and charger are supplied, and the chest moves on castors.
Freezer mode covers −22…−15 °C and cooler mode +4…+12 °C. With R290 refrigerant the chest draws 110 W and uses 2.64 kWh per 24 h (climate class 4). It is 1054 mm wide, 654 mm deep and 916 mm high, with 249 litres gross volume and 68 kg net weight, in white.
