Tough design marked with IP44 rating

Tough design marked with IP44 rating

Popular Dometic products like the CFX3 35 and 75DZ compressor cool boxes and the PLB 40 battery pack are marked with an IP44 rating. IP stands for Ingress Protection, which considers the extent to which a product is protected against penetration by solid and liquid particles. An IP44 rating verifies that the product has been tested and proven to have effective protection against solid objects larger than 1 mm, such as tools and small wires, as well as against splash water from any angle. In other words, your Dometic CFX3 compressor cool box and the PLB 40 portable power pack are splash-proof and therefore fit for the rigours of outdoor use.
