Passive solutions

Deep frozen, frozen, refrigerated and controlled-ambient transport of biological samples and pharmaceuticals

From -78ºC to +25ºC

Our insulated boxes are designed to safely transport biological samples and pharmaceuticals, ensuring the preservation and protection of their integrity. 

By using various high-performance insulators (e.g., graphite, expanded polystyrene, polyurethane, hybrid or vacuum-insulated panels) and coolants (e.g., water/gel packs, dry ice or phase change materials (PCMs), we guarantee a controlled environment for your temperature-sensitive goods.

Extended autonomy for your temperature-sensitive goods:
  • Various sizes and volume capacities, from 4 to 96L capacity 
  • 2 to 7 days dynamic temperature holding time
  • Reusable options with lower environmental impact
  • INFINITY: reliable and reusable
    Eco-friendly packaging
    With Vacuum Insulation Panels (VIPs) and Phase Change Materials (PCMs), it is available in a wide range of sizes and temperature ranges, being compatible with a temperature monitoring device for real-time tracking.
  • Unique: a single-use solution to avoid the cost of return
    It is available in a wide range of sizes and allows for cost-efficient transport. It also has the option of adding a temperature monitoring device. The payload to external volume ratios are industry-leading, which reduces storage and distribution costs.


  • Unique Plus: for special insulation capacity
    The device offers best-in-class autonomy and can hold either pellets or slices.
  • Unique Ultra: for longer autonomy
    For deep frozen temperature. For easy handling, it has a special opening and closing system that does not require adhesives. It is resistant to water, humidity, and moisture.
  • Box Pallet: for large volume capacity
    A certified packaging with wide flexibility in terms of  Dry ice type and quantity.

Our partnerships

We partner with renowned packaging manufacturers to deliver tailored solutions to meet the specific needs of our customers, guaranteeing the safety and integrity of their goods. 

Tower Cold Chain is a UK-based company specialising in the manufacturing of robust, reliable and reusable temperature-controlled packaging solutions for the pharmaceutical industry.  


Get to know two of their passive units:

  • The KTEvolution series is a manually handleable, weatherproof, and washable supply chain solution for the transport of biological samples and biopharmaceuticals
  • The units have the potential to be fully connected with integrated IoT solutions and offer protection from -80ºC (deep frozen) to +20ºC (controlled ambient) for the total safety of your goods. 
  • Using phase-change technology and incorporating vacuum-insulating panels offers complete flexibility of use and requires no external power or human intervention when operating within your supply chain.
