Refrigerating frozen drug substances for storage. Flexible, Stackable, Mobile, Coolable & Scalable. 

RoSS.FRIG is a storage fridge for frozen drug substances in different sizes. It aspires to replace the need for storage freezers when freezing with plate-based freezers at large scales by offering:

  • Great relief for cold room storage capacities due to its high storage density and stackability of RoSS shells
  • Seamless transitions between deep freezing (RoSS.pFTU) and shipping (RoSS.SHIP) or thawing in an end-to-end process
  • High degree of flexibility in-plant due to its portable use
  • A strong helping hand in-plant to prevent staff from carrying heavy loads manually
  • Another way out from incompatibilities of technologies due to its tailored design


  • Isolated container for long-term cooling of drug substances in RoSS
  • Holds desired temperature down to -80°C
  • Available in two scales: small scale for Racks and large scale for Trolleys
  • RoSS.FRIG is stackable itself for highest storage density
  • Ease of use for loading: place loaded Trolleys or Racks as a whole inside
  • Flexible storage location
  • Compatibility to RoSS Systems
  • Contains up to 220l of drug substance

We see issues with integrity of Single Use Systems in the biopharma world. Potentially, the MITS.2D technology is able to help address Endotoxin and Bioburden issues properly. Sterility is key for some applications very close to the patient in Fill and Finish facilities. Midterm, MITS.2D might be able to mitigate the risk of biocontamination in these process steps also.

We were looking for a solid shipping solution for our single use bags. None of the available solutions to date offered reassuring solutions.
Thanks to a fortunate coincidence we got in touch with SUSupport. Not only have we found a more than solid solution for our main problem thanks to their product RoSS® but we now have access to a clever and 100% safe drug substance logistics system.

We were analyzing different solutions on the market for freezing and thawing our drug substances in single-use bags.
The combination of a bag agnostic robust secondary packaging RoSS and the scalable plate based freeze/thaw technologies convinced us to select Single Use Support.
It not only matches all our requirements, it is also safe, easy to navigate and flexible to single-use bags from any supplier.
Furthermore, it is a good starting point to expand to a whole end-to-end solution.
