The VIP is then encased in a polyurethane (PUR) panel to improve easy of handling and increase longevity. These PUR panels are covered in a the reflective material, improving insulation and making the insides of the boxes easy to keep clean. These metallic foil covered PUR panels are housed inside a cloth foil outer liner to further protect the insulation. The Oxford-type cloth covering the top and the bottom sides of the boxes function to reduce damage during transportation and to allow for the easy attachment and detachment of labels and stickers

  • Can I use dry ice with the Kelvin Box boxes?

    Our Kelvin Box boxes are designed to be flexible, the same box can be used for room temperature, chilled, and frozen applications.

    The use of dry ice requires ventilation to allow the evaporating gas to dissipate. The box is constructed in a way to avoid excessive buildup of gases and the Vacuum Insulated Panels will keep dry ice longer than other materials. We recommend wrapping dry ice in paper and a plastic bag or using a liner inside the box to slow down the evaporation process. When handling dry ice, you should always take the recommended precautions, such as using heavy gloves.
