Proportioners which are referred to as 'Positive-pressure proportioning systems' according to the European standard EN16327 are used to generate fire extinguishing foam or surfactant water. Therefore, a foam or wetting agent must be admixed to the extinguishing water flow at a high rate of precision. The relief forces of municipal and voluntary fire brigades as well as factory fire departments need equipment to rely on for their demanding job. This was the focus when the FireDos proportioners were designed, which offer some great benefits for effective fire-fighting. This is what makes the FireDos product concept outstanding: The specially designed water motors and proportioning pumps work flow-proportionally, allowing precise proportioning across a wide range of water flow rates and pressures.
The DZ1000 portable proportioner has been developed, especially for different firefighting scenarios. Highly versatile for mobile use, the DZ1000 guarantees precise foam concentrate proportioning across the entire operating range, from 140 l/min to 1000 l/min. It takes only a few turns to switch between the proportioning rates of 3%, 1% and 0.3% during operation.
