Delta Cargo has approved Envirotainer’s new ‘Releye RLP’ unit load device (ULD) for use on its fleet of aircraft.

The Releye RLP uses rechargeable batteries to power its electric heating and compressor cooling system and can power the whole system for over 170 hours on a single charge.

Envirotainer claimed the new ULD delivers up to 90 per cent reduction in CO2 emissions compared to alternative 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 Delta Cargo’s managing director cargo commercial Jannie Davel.

Envirotainer’s head of global key accounts (airlines) Don Harrison added: “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.”
