With its innovative bag-in-plate design, the Safecore™ Technology provides exceptional protection to Celsius® FFT|FFTp in a proven design format that is scalable from small to large-size single-use container. Celsius® FFT|FFTp along with its purpose-designed shippers (Celsius® FFT|FFTp Box and Celsius® FFT Bulk Shipper) offers enhanced process capabilities to create a versatile approach to to protect your product in conventional manufacturing.

Safecore™, bag-in-plate (cassette) design

  • Plates protect the bag and lines by adding impact resistance, suppressing wrinkles and restricting degrees of freedom
  • Excellent bag-to-plate contact provides high robustness and more uniform freeze/thaw, plates compress the bag to reduce ice bulging formation
  • Container assembly is tool-free and intuitive for minimum risk during production assembly

Maximum Robustness down to -80°C

  • Material selection based on characterization of physical and thermal properties across wide temperature range to ensure suitable use for the intended application
  • Handling and shipping qualifications built on deep understanding of mechanical stresses occurring during lifecycle for reliable performance in real-world environments
  • Storage and shipping operations down to -80°C, multiple freeze-thaw cycles, shipping qualification according to ASTM D4169 at Assurance Level 1 method

Simplified Operation

  • Plates are transparent with bag chamber fully visible for product inspection
  • Configurable with various connector/disconnector technologies, easy wipe down
  • Sample bag compartment to store/ship sample bag, label adhered to the shell for full product traceability, label placard for end-user labelling

Bulk Processing

  • Bulk Shipper minimizes storage and shipping density and reduces associated risks during handling with multiple frozen containers per pallet
  • Compatible for truck and ocean transportation in refrigerated environment as is, compatible with any type of thermal insulated shipper for air transportation
  • 2 shipping solutions: Box and Bulk Shippers, qualified according to stringent regulations for shipping containers
