Thermoelectric: adopts our patented aqua cooling system, system cycles on/off to maintain stable cabinet temperature with anti discharge car battery protect. The only freezer, cool box and heater all in one box. A completely new technology allows this new freezer/cooling/ heating box to work from up to 60 deg C down to -10 deg C, enough to heat or freeze food and more importantly, cool the beer all the way down. The box is a rugged plastic construction with an internal aluminum cooler. The newly developed principle uses lightweight thermo-electric elements with a patented liquid cooling system. This gives all the cooling power of a much heavier and much more expensive compressor fridge (cools down as low as -10 deg C), and all the heating ability of thermo- electric systems (heats up to 60 deg C). It can be used either as a freezer, cooler or heater. Input voltage: 12 volt. The digital thermal control system allows highly accurate temperature selection to reduce power consumption and to enable food to be frozen at the correct temperature. The units also come with a 230v power adapter to allow food to be prepared and cooled even before transporting. Unit comes complete with bag and trolley. 1��cooler with foldaway handles and detachable lid 2��C line with the cigarette plug (optional: AC/DC adaptor) 3��manual 4��basket Model Input power cooling NW/GW cub size(mm) BR36SL-ID DC12V-24V 60W 28-32°C lower than ambient temperature 13/15Kg 36L 645*410*645 BR36SL-IA DC12V-24V 96W 35-40°C lower than ambient temperature 13/15Kg 36L 645*410*645 BR36SL-IB DC12V-24V 150W 40-45°C lower than ambient temperature 13/15Kg 36L 645*410*645 Warming performance: up to 55 degree c Loading capacity: 456pieces 40HQ BR36SL-II Model Input power cooling NW/GW cub size(mm) BR36SL-IID DC12V-24V 60W 28-32°C lower than ambient temperature 13/15Kg 36L 575*385*615 BR36SL-IIA DC12V-24V 96W 35-40°C lower than ambient temperature 13/15Kg 36L 575*385*615 BR36SL-IIB DC12V-24V 150W 40-45°C lower than ambient temperature 13/15Kg 36L 575*385*615 Warming performance: up to 55 degree c Loading capacity: 480pieces 40HQ
