Delta Cargo announced that it has approved the Envirotainer Releye RLP for usage on their fleet of aircraft citing increasing growth in demand for temperature-sensitive cargo.

Envirotainer offers cold chain solutions for air transportation of pharmaceuticals.

In a statement, Delta said with this approval, it can now transport the Releye RLP on their wide-reaching global network, increasing the capacity "to meet the ever-growing need for temperature-controlled, high-quality, connected ULD solutions."

"The introduction of the Releye RLP, in combination with our CEIV certified pharma network, provides our customers with more choice when looking for reliable container options to support the growing demand for pharma and vaccine shipments," said Jannie Davel, managing director Cargo Commercial at Delta Cargo.

The Releye delivers up to 90% reduction in CO2 emissions compared to available passive solutions, based on life-cycle analysis. The unit also uses rechargeable batteries to power its electric heating and compressor cooling system and can power its system for over 170 hours on a single charge.

It also offers live monitoring for product condition, location, temperature, humidity, battery levels, door openings, if cargo is loaded or not and the progress of shipments.

"With the new Releye RLP, Delta Cargo can offer their customers the latest active fully connected solution to protect the integrity and quality of air freight medicine products throughout the supply chain," said Don Harrison, head of global key accounts, airlines at Envirotainer.
