Profile: Knorr-Bremse Systems for Commercial Vehicles Ltd. manufactures braking systems for rail and commercial vehicles. Our products for rail vehicles include braking system, door system, air conditioning technology, derailment detection, windscreen wiper system and control components. We also produce AC & DC contactors & disconnectors, resistors and electronic devices for both industrial and railway applications. Our resistors include brake, damping, snubber, filter, charging and discharging resistors. Rheostatic braking allows the vehicle`s kinetic energy to be dissipated electrically, preserving mechanical brake consumption with non-receptive lines or with diesel electric traction. The energy is dissipated into heat through brake resistors.
