High Frequency Vibrators

are the right choice for wet-cast compaction and specific requirements.

BRECON high frequency vibrators generate amplitudes from 6.000 r.p.m. for standard wet-cast applications and up to 9.000-12.000 r.p.m. for specific requirements like e.g. in large concrete pipe forms.

Wet cast concrete only consolidates at frequencies between 4.500 and 6000rpm with a proper quality. Just the right frequency guarantees a perfect compaction without the risk of disaggregation. With a variable drive it is possible to determine the optimum frequency where the concrete consolidates in shortest time and with highest density.

The ideal frequency for each mixture can be adjusted by frequency inverters that are indispensible for operating high frequency vibrators. The highest quality can be reached with our Synchronous External Vibrators. more...

basically allow to vary the speed of the vibrators during operation.
This enable you to adapt the centrifugal force to different types of mixtures and moulds without having to change the mechanical settings of the vibrators.

The additional features of a control system can be to operate the vibrators in defined groups and cycles. Control Systems can include remote control, frequency displays and touch screen visualisation.

BRECON is worldwide the only manufacturer of synchronously running external vibrators (SL vibrators). Unlike the standard asynchronous vibrators where the slip between rotor and stator causes each vibrators to run with a differnet speed, all  BRECON SL vibrators rotate with exactly the same revolutions per minute.
