Electric Screed Heating

Installed in all VÖGELE screeds.

Through decades, VÖGELE have gained a wealth of experience in electric screed heating, which has been installed in all VÖGELE Fixed-Width and Extending Screeds since 1952. Electric heating provided for all compacting and smoothing screed elements heats them up and maintains an ideal temperature while paving. In all VÖGELE tractor units, powerful and sturdy three-phase A.C. generators are installed supplying electric power for screed heating. An intelligent Generator Management brings highest efficiency.

In order to support compaction and produce a smooth surface texture, all compacting elements are heated across the full screed width. Screed plates are fitted as standard with heating elements distributing the heat all over the plates. Heating elements are perfectly insulated to prevent loss of heat to the upper environment. As a result, the heat is directed 100% to where it is needed, in fact to areas of contact with the hot mix. Tamper bar and pressure bars are fitted with heating rods for quick and uniform heating from inside. Sophisticated technology is installed allowing automated control of screed heating.

Generator Management

An intelligent Generator Management system ensures that, irrespective of engine rpm, the generator output needed for heating the screed in its current pave width is made available at all times. Heating the screed’s compacting systems to operating temperature takes a short time only even with the engine running at minimum rpm. When paving with paver functions set to automatic, the Generator Management activates screed heating in Alternating Mode which cuts electric power required for heating and reduces fuel consumption.

The Benefits of VÖGELE Generator Management at a Glance

  • Alternating Mode cuts electric power required for screed heating and reduces fuel consumption.
  • Screed heating even at minimum engine rpm takes a short time only, so that the paver is quickly ready for operation.
  • Uniform and constant screed heating adds to high pavement quality.
