Our company was formed in 1977 in Bad Mergentheim, Germany. The starting capital consisted of patents arising from research on 'FLUIDICS'. These are devices which without moving parts, can automatically regulate the flow of any fluid in response to the strength of the current. This initial research mirrors the activity of the firm today, with innovations like the Vortex Throttle and the Vortex Valve we have specialized in the control of storm water and sewerage flows.
