    It is recommended to deep freeze all gel ice bricks for min.12 hours at -18°C before use. Place frozen ice bricks inside the foil pockets in the cooler box. When temperature on the display reaches the desired temperature, place products inside the box and close the lid.
    Cold life may be affected by direct sunlight, volume, density and temperature of payload on loading, frequent opening of the lid or incorrect conditions of the cold packs.

    It is not recommended to use water based ice packs for vaccine and medicine transport. Our ice packs are medical grade gel based, designed specifically for transport of pharmaceutical products that will keep the required temperature for longer duration.
