In many homes, using the kitchen tap and shower can cause temperature fluctuations which are dangerous for the users, this situation is originated by a typical activity in everyday live: the changes in the water pressure while opening or closing other taps.

There are on the market other devices that minimize these temperature fluctuations but do not reach an unnoticeable experience for the user and they are not able to provide a pressure independent flow.

In this context this Spanish company, which is specialised in energy and water efficiency, has developed a small flow controller unit for thermostatic and non-thermostatic (shower) mixers, capable of provide a constant flow, eliminating the influence of pressure and reducing temperature fluctuations.

This flow regulating technology is a combination of a high grade engineering plastic housing with a balancing valve made from custom made stainless steel. These materials are extremely durable and respond well to changing pressures.

Key features:
• Optimal water temperature stability
• Optimal flow control
• Definition of peak volume demand per mixer
• System stabilisation
• System pressure loss reduction

All these key features make this small device suitable for houses and commercial businesses, particularly those with a larger number of showers such as hotels. Easy to install at the hot and cold water inlet of thermostatic and non-thermostatic mixed showers: the existing shower bar is removed and the connect units are install onto the inlets flows, after that, the shower bar is refitted.

Other technical specifications are:
• Weight: 63 g
• Max. operating temperature: 90 °C

With a large experience in energy and water efficiency sector, the company is looking for increasing its international business development by looking for international distributors to commercialize this flow controller unit.

Advantages & innovations

- There are other rubber based devices with similar purposes on the market, which are able to reduce the pressure fluctuation to 10%. However, this fluctuation is still noticeable for the user resulting in an uncomfortable experience. - The technological solution proposed is the only one certified that produce constant flow regardless the variations of the water pressure system. The fluctuations of the flow are about 0.3 % or less. - The temperature fluctuations are reduced by technically 90% compared to the rubber based devices, resulting to the comfortable shower for the users. - Contribution to the reduction on water and energy consumption. - The product meet the requirements for Kiwa Water Mark and primary European drinking water standards.
