Additional Premium PU Insulation
Unlike other manufacturers, Coleman rigid coolers are insulated with Polyurethane insulation (PU). PU is a very dense and an excellent insulator filling the entire internal cavity of the cooler, leaving no air gaps and so improving its insulating efficiency.
Extensive testing at Coleman has shown that cooling loss from rigid coolers is 30% through the top and also 30% through the base. Coleman’s latest models feature increased insulation in these particular areas together with reduced insulation on the sides. The result of these changes is not only improved cooling performance but the reduction in exterior dimensions and the increase in internal volume.
A New Shape and Increased Efficiency
When a cooler comes in contact with a warm floor, heat is transferred directly from the floor to the cooler and reduces the cooler’s efficiency. Coleman has included shaped feet into the design of its newer rigid cooler models separating the cooler base from the floor and increasing airflow. This flow of air acts as an additional form of insulation, slowing the transfer of heat from the floor and so improving the coolers performance. Additional research has also resulted in the rounding of the cooler’s corners, once again this change of shape has increased airflow and further enhanced their performance.
Antimicrobial Liner – Resists odor, mold and mildew
The Antimicrobial additive is bonded in the material and there is no risk of it being scratched or washed off. It is very strong and won’t weak over time – it’s there for the life of the product.
The Antimicrobial barrier ensures the product resists mold and mildew growth and it also blocks unpleasant odors from developing.
It is totally safe. The active ingredient in the antimicrobial substance is also used in common dandruff shampoos and artificial food additives. Consumers come in contact with the substance daily and in some cases digest it without any ill effects. The Antimicrobial surface is environmentally and eco-friendly.
