Once an effective COVID19 vaccine is available in the required quantities and is to be delivered to the vaccination centres, a specific logistical task also needs to be addressed: The vaccine must be transported at a temperature of at least -70oC to -80oC and stored on site at the vaccination centre. L&R Kältetechnik has developed a safe, flexible and economical concept for this demanding type of deep-freeze storage: a deep-freeze storage system that is installed in an industrial container.
