DoKaSch Temperature Solutions has expanded its fleet of Opticoolers with 50 new RAP containers, passing the 500 mark.

“We are proud that our products have proven worthy in the day-to-day air cargo business and that we can offer our customers an extremely reliable product,” said Andreas Seitz, managing director of DoKaSch Temperature Solutions. “We therefore provide a solution to tackle the difficulties in the global cool chain logistics.”

The company’s Opticoolers are equipped with battery-powered cooling compressors and heaters, and are capable of maintaining shipments at specific temperature ranges.

Only one electrical outlet is required to fully charge a container. A charge from 50% to 100% can be achieved in approximately two hours.

The Opticooler was originally developed for Lufthansa in 2004, according to DoKaSch.
