The Turbinator is available with capacities to suit most applications and can be used in fixed systems or as a mobile unit such as fire trucks, trailers and hand-portable use.

The Turbinator consists of two main parts: a water driven engine and a foam concentrate pump. The motor and pump are connected and integrated in a compact housing.

More information

Foamtronic is an electronic foam mixing system which very accurately mixes foam concentrate & water based on the actual fire demand of the system.

Designed for high value foam systems, the accurate mixing of foam concentrate and water 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 FoamTronic.

The control system records all process values and alarms during operation or test which are available via a user-friendly interface.
