Solution overview

The KTM42D is a double-pallet ultra cold temperature-controlled packaging solution for the transportation and extended storage of products that require an internal temperature range of <-60˚C. Using 200kg of dry ice the KTM42D double-pallet ultra cold can transport two Euro pallets of product at <–60°C for more than 94 hours, and 227 (nine days) when stored in a (-20°C) freezer. The dry ice can be replenished during the operation of the system to extend it’s performance indefinitely when used for ultra-cold storage. The KTM42D’s data logger ensures door-to-door-compliant payloads with no human intervention throughout transit. Suitable for use with wide-bodied aircraft, reefers and all road-transport options.

Evaluation Criteria

  • Fewer than 0.1% temperature excursions on average (data supported from over 15,000 shipments)
  • Easy load and unload process through double door access
  • No external power or human intervention required during transportation
  • Integrated blue tooth data logger (RTCA DO 160G Part 21 H Compliant)
  • Operational Qualification completed to customer loading and shipping specification.
  • Global Qualification with near zero thermal mass which stress the containers far more than step tests, reducing associated documentation by half.
  • The KTM42D ultra-cold double pallet is a fully reusable circular supply chain solution.
  • Easy and quick reconfigure for subsequent shipments.
  • Global availability through our global hub network within 24 hours or less.
  • Global assurance, used by a wide range of pharmaceutical companies organisations.
  • Product is held at temperatures less than <-60°C for 94 hours (4 days)
  • Turns all existing infrastructure (-20°C) freezers into under <-60°C deep-freeze units with hugely-reduced running costs, reliability and industry-standard health and safety.
  • When stored in a (-20°C) freezer unit the KTM42D maintains <–60°C for over nine days and can be replenished with dry ice in under five minutes, providing unlimited deep freeze time.
  • Provides the largest single industry shipment (two Euro pallets) within airline dry-ice limitation (250kg per container) whilst maintaining <–60°C for over 94 hours.
  • Under five-minute load-and-reload time allows minimal human contact with dry-ice. Industry-leading health and safety working conditions maintained throughout.
  • Temperature is consistent throughout the payload so no temp differentiation in container.
  • Allows remote locations and lorry reefers with freezer capabilities to have deep-freeze capabilities.
  • Allows for multiple units to be maintained within -20°C freezers with limited unskilled workforce.
  • Product can be held at temperatures under <-60°C for an unlimited time if dry-ice is consistently replenished.
  • Product is held at temperatures under <-60°C for 227 hours (9 days) when transported in under -15°C – under 25°C temperature.
  • Unique easy lock-and-load process, part product can be removed from the container without undue issues or affecting internal temperature.

Data Logger
Data Logger

Data loggers are built into all KTM42 Double-Pallet Ultra Cold containers, logging internal temperatures from -95°C (-139°F) up to 50°C (122°F). Users can get text or email notification of temperature excursions, as well as automatic data downloads throughout the transit (in-flight excluded) from loggers within range of the CX Gateway device. The loggers are built to FDA, USP, EU and WHO standards.

Product Testing
