SmartMix is an electronic foam mixing system which very accurately mixes foam concentrate and water, based on the actual firewater demand of the system.

This is achieved by continuous monitoring of the firewater and foam concentrate flows, using electromagnetic flowmeters and real-time adjustment of the concentrate control valve. The accuracy and stability of the system is based on the combination of specially selected components and a unique control system with state-of-the-art logic developed specifically for SmartMix. The control system records all process values and alarms during operation or test which are available via a user friendly interface.

SmartMix allows system performance to be regularly tested without mixing foam and water, thus avoiding environmental concerns and depletion of valuable foam stocks.

Foam proportioning systems rely on the accuracy of the percentage mixing ratio of foam concentrate to water, with the SmartMix technology this accuracy can be controlled to finite levels and will automatically adjust to changes in system demand.

An advantage of the SmartMix is that there is no pressure loss in the water supply towards the extinguishing systems. The SmartMix can be installed close to the foam storage or on remote locations where multiple SmartMix systems can be used on site using a centralized foam storage system.


The SmartMix can be adjusted to match project specific requirements and components will be selected to ensure optimum operation. The system capacity depends on the allowable pressure drop over the flow control valve which is sized to suit each application. Examples of system capacity are indicated for 1% and 3% mixing ratios.

The SmartMix system up to DN50 is standardized into the same cabinet, larger sizes are available and will be custom built. Other flow rates are available up on request.
