Fluid E63 has been developed particularly for the use on construction sites with conventional electricity supply. With its frequency regulated three-phase current engine the Energy Plus can be connected to every power distributor provided on construction sites. Operational safety is guaranteed at all times. Performance may be adjusted from 50 to 63 Ampere on site. The 30 kW variable frequency engine lands the Energy Plus all its power without producing exhaust pollution or CO² emissions. The noise pollution is also dramatically reduced.
