The Tempcell™ MAX shipper is an upgraded version of its Tempcell™ brother. An innovative, internal radiant barrier film has been added to enhance thermal protection. And advanced PCM coolants replace water-based coolants. This allows the temperature-stable operating bracket to function for 48 to 96 hours. PCM coolants are also capable of true end-of-life recyclability and contribute towards a lighter shipper, enabling cost-effective transportation.
