The Progressive represents a new type of efficient energy-saving single-handle faucet. In particular, it is the compact design which stands out. The Progressive sets new standards with a diameter of 25, 29 or 33 mm and previously unattained ease of operation.

When the Progressive is turned on, at first only cold water comes out. This avoids the problem of wasted hot water which occurs with traditional single-lever cartridges.

In addition, the easy operation and movement makes it possible to use small, attractive faucet handles. From the aspect of its overall design, a single handle faucet equipped with the Progressive fits seamlessly into the product line of two-handle faucets. The advantage of this design is further enhanced by its small diameter.

How the Progressiv functions

When the spindle is turned clockwise, the Progressive opens the volume flow of cold water. Turning the spindle further activates the mixing process by adding hot water. At the end of the turning area, only hot water flows.

The Progressive's shut-off function always takes place via the original starting position.
