The ACCEVAL BCB-1 Control Box (*) is used to control the TPRS (Tire Pressure Refill System) of trailers and semi-trailers.


  • Maintain preset tyre pressures to minimise tyre wear.
  • Maximise fuel economy.
  • Avoid possible tyre blowouts.
  • Minimise tyre maintenance time.
  • Avoid downtime due to punctures.

(*) EMC R10 Certificate

How does it work?

BCB-1 takes compressed air from the vehicle’s pneumatic system and, when necessary, refills the wheels with air through its connection to the TPRS wheel elements (stators, rotors, hoses, etc.) that are not part of the Control Box.
