Wienhoff tire pressure regulation system (RDA)

Simple and safe control and regulation

Special features:

  • Large lubricating oil cooler ensures uninterrupted operation of the compressor
  • Air filter and oil filter are easily accessible under the protective cover
  • Direct drive of the compressor (no V-belt transmission etc.)
  • Control unit can be fully integrated into WieTaCon operation or controlled via an external control unit
  • the buttons and display of the WieTaCon-8 can be dimmed automatically
  • Optional compressed air supply for the towing vehicle
  • The tire pressure can be inflated and deflated individually per axle or together via
    a button (tractor and drum)
    The tire pressure is released via a silencer, which greatly reduces the
    background noise
  • The robust hot-dip galvanized protective hood is supported by a gas pressure damper when opening and is held in the end position, making maintenance easy
  • Easily accessible mounting points of the tire controller enable simple
    attachment to the vehicle
  • the favorable central position of the hydraulic lines allows easy connection to the hydraulic system of the towing vehicle
  • The Wienhoff RDA can also be retrofitted to tractors as an optional accessory
