Funzione LEFF® - Low Emission Flip-Flop

At GEA we are continually innovating to improve our customers’ efficiency, reduce their consumption of valuable resources and improve sustainability.

The LEFF® function integrated in GEA T.VIS A-15 control tops has been awarded the GEA Add Better label* for its positive impact on reduced water consumption. Conventionally, mixproof valves run a time-based seat lifting cycle to clean valve seats and intermediate cavity. The LEFF® function is the smarter, more efficient way. The valve opens in a pulsating mode, controlled by path-measuring instead of fixed intervals. This increases the intensity of flushing and effectively shortens flushing times for water and chemicals. It has been proven to saves up to 92% of water and cleaning agent used.

^{*The add Better label relates to the LEFF® function integrated in GEA T.VIS control top, released in 2003, which saves 92% of water in comparison to conventional valve seat cleaning.}
