The SAF TRAKr generates energy by using recuperation. Energy is generated during braking or overrunning and is stored in a Li-ion battery by the conversion of the TRAKr. The energy can also be used for the cooling units, heaters or hydraulic platforms while the trailer is moving. The main applications are refriderated trailers, food tankers and silos and help with reducing fuel and particulate emission.
