This unit can be used as either a Freezer or Fridge, and can maintain -18oC even in +43oC ambients. The 60mm thick wall insulation and complete coverage wall and floor cooling plates ensure the lowest possible battery consumption, making this one of the models ideally suited as a permanent portable freezer or extreme duty fridge. 12/ 24v DC and 240v AC are all built in and the unit will automatically select to run on mains power whenever it is available - but revert to battery power if the mains go off. A digital thermostat that can be set down to as low as minus 30oC ensures the unit maintains your desired temperature range without the need to adjust for hotter or colder weather. Ripple stainless steel outer cabinet for maximum durability and ease of cleaning. Three (3) baskets fitted as standard.
