FOAMJET 12E/12EH is positive pressure proportioning system (EN 16327-PPPS) with digital control used to maintain selected constant foam-water proportion regardless of water flow fluctuations. The system accurately delivers foam concentrate from 0.1 % to 6 % through a check valve/injector fitting, directly into the water discharge stream of the fire pump. The system can be setup also as a high-pressure unit allowing an injection pressure even up to 50 bars. In this case safety relief valve and flow meter enclosed are rated for PN50.
The proportioning system uses electrically driven foam pump. The pump and motor drive are designed for long-term load with over-temperature and current protection. High quality industrial components as well maintenance-free brushless motor (BLDC) ensure top performance of the injection system.
