For such dispersion machines as dissolvers or basket mills, the European Directive 2006/42/EC requires not only purely mechanical safety devices but also control-related redundant safety measures. The rotating drive shaft must be protected by a shaft protection pipe. At a certain drive power or above, the container opening must also be protected by a cover or safety guard.

The machine may only be put into operation if:

• a container is available and securely clamped,
• a dissolver disc or milling basket is within the container,
• safe stop of the drive motor can be ensured by the STO function (Safe Torque Off),
  and
• the electrically driven lifting column can be securely shut down.

A complete set of safety devices in the machines must be used to meet the functional safety requirements set forth in EN ISO 13849-1. Although these functions are mainly implemented with electromechanical auxiliary components, we integrate the DISPERSAFE® safety module, specially developed for this purpose, into our DISPERMAT® machines. This smart and processor-controlled module guarantees the highest safety standard for dispersing machines.

Our DISPERSAFE® safety module enables the use of variable container sizes by “teaching in” container parameters on the control panel simply and conveniently.
