MRT Control Unit

For automated control of MRT Spinning and Blasting Unit

The MRT Control Unit provides the opportunity, as control module for the preparation
of sewer wall surfaces and coatings, for automised control of both processes.

Operation during substrate preparation and coating is carried out outside the manhole.
Easy handling and rapid operation on site characterises the system. The casing and the
control elements are robust and designed for practical operation.

By means of the remote control the entire process is automatically controlled by an
integrated measurement system. The user has full control functions. The time saving
compared to hand application is up to 80%
