The Technical Bit
By studying different types of rainfall, we realised that if we could deliver water in a way that made the most of its natural properties, we would dramatically improve the efficiency of existing shower heads. We achieved this by removing the traditional spray plate and inserting a turbine vane into the chamber.
The Turbine Vane
Water travels along the shower handle at full pressure to a compartment in the shower head where it is deflected backwards into an expansion chamber. This action causes pressure to build and when it reaches a certain level, the water bounces back out of the chamber. The resulting pulsation occurs between 30 and 40 times per second and manipulates the surface tension of the water to ensure that the pressure is as high as possible in every single drop.
The savings can amount to up to a 60% reduction in water use, without a drop in the existing pressure.
Rather than creating an illusion of more water by filling the flow of water with air – as in aerated eco shower heads – Pulse Eco Showers simply maximise the propulsion and impact of fuller drops while consuming less water and energy.
What's more, the measures taken to achieve these effects have created extra benefits unique to Pulse Eco Shower. By removing the spray plate, our engineers have dramatically reduced the internal surface area where deposits and minerals can build up; guaranteeing a more hygienic shower and no lime scale clogging for life.
