Cold accumulator, 400 ml, size 18*8.2*3 cm Description: The cold accumulator has an increased volume of 400 ml. The cold accumulator is a plastic container filled with a substance with high heat capacity. Cold accumulators are used as main cooling elements in cooler bags and allow for maintaining the optimal temperature at which the products will not spoil. Before going on a journey, the cold accumulators are placed in the freezer, where the substance cools down to the desired temperature for a long time (10-12 hours). After that, the accumulator placed in the bag is capable of absorbing heat for a long time. The active substance here is a solution of carboxymethyl cellulose, water, and glycerin. The calculated amount of accumulators required to maintain the temperature in a thermos bag is 200 ml per every 6 liters of volume. Advantages: Large volume, high heat capacity, safe and environmentally friendly solution.
