Diab reports that its structural core material has been used in a sandwich composite structure to make a temperature-controlled air cargo container to transport Covid-19 vaccines globally.
The RAP e2 container, made by Envirotainer, offers almost twice the insulation value compared to an equivalent aluminum/polyurethane (PUR) container, reducing the size of the battery pack for the temperature control system. The interior temperature can be maintained at a constant temperature from -20 to +40 °C and it can withstand more than a 23-ton static load on its roof, Diab says. Due to the sandwich composite design, the Envirotainer engineers were also able to develop a vacuum-assisted resin transfer molding (VARTM) manufacturing process that allows series production of the containers.
‘Envirotainer is proud to be part of the efforts to transport both ongoing Covid-19 trial shipments as well as the upcoming global shipments of the Covid-19 vaccine,’ said Bernt Anderberg, CTO at Envirotainer. ‘Working together with partners like Diab helps us deliver a safe and secure solution for the life-saving medicines that people depend upon.’
