SORL Awarded Electric Air Dryer Patent

SORL Auto Parts SORL today announced that the Company obtained a patent in the People's Republic of China ("PRC") for a new proprietary electric air dryer that is specifically designed for new energy electric buses and specialty commercial vehicles. Equipped with an internal electronic control unit to achieve continuing desiccant regeneration, SORL's new electric air dryer has a prolonged useful life and improves the working environment of the vehicle's air control system. As a result, the dryer extends the operating life of the entire air control system and improves the vehicles' safety performance. The patent will be in effect from 2012 through 2030. Desiccants in the air dryer are used to absorb moisture and dust to make sure the compressed air is clean when it goes into the air control system. Eventually the desiccants can become full of moisture and dust so the dryer becomes ineffective. Desiccant regeneration prevents moisture and dust saturation to ensure continued dryer operation.  A traditional air dryer controls desiccant regeneration through the cut-off pressure within the drying See full press release
