Think dry ice is the only way to protect your deep frozen product as it travels between destinations? Not anymore. Minneapolis-based Entropy Solutions, Inc., has introduced a new variation of its patented PureTemp renewable phase change material — it replaces dry ice, and maintains a consistent payload temperature of -40°F.

“We have high-value, sensitive products that must be shipped within the deep-frozen temperature range to maintain efficacy, and were looking for a solution that addressed the adverse effects of dry ice, while providing a more cost-effective, environmentally-friendly option,” explains Donnie Wilson, senior manager for engineering at Amgen. “We have been very pleased with PureTemp’s performance – early results demonstrate that, when used in the GREENBOX Pallet Shipper, it maintains our required temperature while our packages are in transit.”

Some Notable Product Features Include:

• While dry ice can be used one time only, PureTemp can be used more than 20,000 times with no thermal degradation
• While dry ice emits carbon dioxide, PureTemp produces zero emissions and is a 100 percent renewable, biodegradable and earth-friendly phase change material
• While dry ice shipments face restrictions due to carbon dioxide emissions, PureTemp is not restricted in any mode of transportation as part of the GREENBOX Thermal Management System
• While dry ice complicates the handling of a shipment, such as replenishment needs, PureTemp requires no special handling
• While the use of dry ice may alter the pH levels of certain drugs, PureTemp is safe for use with any product – for example, pharmaceuticals, plasma, clinical devices or even food items – that needs to be kept at deep-frozen temperatures throughout the duration of a shipment.

About Entropy Solutions’ mission is to provide renewable, innovative, cost-effective, temperature-controlled solutions for the shipping, construction, textile, healthcare and alternative energy industries.
