Benefits: Braking resistors allow Altivar Process drives to operate while braking to a standstill, by dissipating the braking energy. They enable maximum transient braking torque., Located outside of the enclosure, without inhibiting natural cooling, Braking units provide IP20 and IP23 protection and thermal protection is given by an integrated temperature probe.. Applications: Altivar Process ATV900 drives have been specifically designed for industrial processes, such as: . O&G: . Electrical submersible pumps, progressive cavity pumps, rod pumps, mud pumps, rotary table/ top drive, draw works and regasification compressors and refinery fans... MMM: Stackers/reclaimers, mills/kilns, crushers, grinders, mixers, conveyors, special cranes and ship loaders.. F&B: Dairy beverage and agribusiness applications including conveyors, mixers shredders, centrifuges and hot rotary dryers.. WWW: Decanters in various water and wastewater applications....
