Specifications
The Tegrant Thermosafe ThermoSafe Insulated Shippers, Polyurethane, Thermosafe Brands E168UPS 5.1 Cm (2″) Wall Thickness is built with a focus on thermal integrity and durability. Its defining feature is the 5.1 cm (2″) wall thickness, composed of a closed-cell polyurethane foam core. This dense insulation is key to its long-range temperature protection capabilities, designed for both frozen and refrigerated products.
The construction involves a proprietary process that laminates this highly efficient insulation core to both inner and outer corrugate walls. This layered approach provides structural rigidity without adding excessive weight, making the shippers lightweight yet robust. A crucial element is the flexible polyurethane foam plug that serves as the top seal; it cushions contents, further insulates, and importantly, allows for necessary dry ice venting. The dimensions are generous for its class: interior dimensions are 59 x 23.5 x 34.3 cm (231/4 x 91/4 x 131/2), while the exterior dimensions measure 71.1 x 35.6 x 52.7 cm (28 x 14 x 203/4). This substantial wall thickness, coupled with the quality materials, translates directly into superior temperature holding capabilities compared to shippers with thinner walls or less efficient insulation types. The fact that it’s CFC- and HCFC-free is also a responsible design choice, reflecting an awareness of environmental impact.
