Spotlight On: Evaporative Cold Chain Technology
Evaporative technology creates cold chilled (2°C to 8°C) conditions through the natural process of water evaporation from one package chamber to another. This innovation is considered “off the shelf” cold chain as it can be simply pulled from storage and activated. Within a short period of time it conditions the container to chilled specifications. With no electricity required to condition cold panels, freeze cold packs, or create ice, it can be activated in any location, and it’s environmentally friendly. This technology is a great solution for shipping pharmaceutical products to remote locations throughout the world.
Cold chain logistics can employ a multitude of different container types to meet in-transit temperature requirements, which generally fall within the following ranges:
- Cryo: -150°C (-238°F)
- Dry Ice: -80°C (-112°F)
- Frozen: -20°C (-4°F)
- Chilled: 2°C to 8°C (35°F to 46°F)
- Controlled Room Temperature (CRT): 20°C to 25°C (68°F to 77°F)
Active cold chain containers generate cold inside the packaging and adjust the internal temperature in response to external conditions to maintain a constant temperature.
Passive cold chain containers utilize cold panels, dry ice, ice packs, and other cold material to create internal conditions that meet product temperature requirements, but do not respond to changes in outside conditions.
If the required freeze time is greater than 36 hours, frozen ice packs will not maintain a frozen product. In this case, an insulated box will require the use of dry ice. Although dry ice is -80°C and product may only require -20°C, note that separation from touching the dry ice by at least one inch will have the desired effect of creating internal conditions of -20°C. Longevity of the frozen product will then depend on the amount of dry ice included.
