12 litre car Cooler/ Freeze-and-Heat Box. 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.
