BRECON External Vibrators
High Frequency Vibrators
BRECON high frequency external 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 6,000 rpm 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 indispensable for operating high frequency vibrators. The highest quality can be reached with our Synchronous External Vibrators.

Possible applications for BRECON high frequency external vibrators
Wet cast concrete compacting
Wet cast concrete offers through its liquidity an enormous flexibility, being suitable for realizing almost any kind of elements. Due to this, pre-cast plants using wet cast concrete have to adapt the compaction constantly to new elements, designs and sizes, usually in small custom-made series.

FAQ – High frequency vibrators
What are high frequency vibrators used for?
High frequency vibrators are the right choice for wet-cast compaction and specific requirements. For standard wet-cast applications they run at 6,000 rpm, for specific requirements such as large concrete pipe forms at up to 9,000–12,000 rpm.
Do I need a frequency inverter?
Yes. Frequency inverters are indispensable for operating high frequency vibrators. They also allow the ideal frequency to be adjusted for each mixture.
Which speeds and voltages are available?
BRECON offers high frequency external vibrators with 6,000, 9,000, 10,800 and 12,000 rpm, depending on the version for 42 V, 190 V, 230 V, 250 V or 380–415 V. You will find the exact values in the range overview and in the product catalog.
What is the difference to synchronous vibrators?
With standard asynchronous vibrators, the slip causes slightly different speeds. BRECON synchronous vibrators run at exactly the speed set on the frequency inverter, which achieves the highest compaction quality.
Are the vibrators available for other voltages?
Yes, all BRECON vibrators are also available for special voltages.
