TASOWHEEL COATER PROFILER

Compact and efficient Coat Weigh profiler

  • Uniform Coat weight profiles
  • Fast recovery after process disturbance and blade or rod changes
  • Enables high coat weight level with a good profile quality
  • Actuator (CA-5000) sensor directly on the output shaft -> Accurate and fast positioning
  • Actuators located close to the rod on top of the blade
  • Electronics are located in over-pressurized boxes close to the actuators. This unique design prevents coating color and water from getting inside the profiler or its electronics.

Benefits

  • Less blade/rod changes due to minimized wearing
  • Easy installation ensures a short shutdown period
  • Better runnability due to good Coat weight profiles
  • Less broke after breaks and blade/rod changes
