Solution overview

The KTM21 Tower low Euro pallet is an easy to load half-height Euro pallet circular supply chain solution providing 120-hour product protection for -20°C (frozen), +5°C (refrigerated) and +20°C (controlled room temperature). Using phase-change technology it offers complete flexibility of use and requires no external power nor human intervention when operating within your supply chain.

Evaluation Criteria

  • 120 hours product performance
  • One pack-out configuration providing 20°C (frozen), +5°C (refrigerated) and +20°C (controlled room temperature) internal temperature range
  • 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 bluetooth data logger (RTCA DO 160G Part 21 H Compliant)

Data Logger
Data Logger

Data loggers are built into all Tower 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
