Balanced Foam Proportioning Device
Continuous Liquid Supply & Sufficient Storage: Continuously replenishes foam concentrate during operation, combined with a large-capacity storage design, ensuring more reliable emergency response.
Stable Operation & Efficient Fire Suppression: Accurate proportioning and resistance to pressure fluctuations for controllable fire extinguishing effect; quickly forms a high-quality foam layer to block the fire source.
Wide Application Scope: Covers various places such as logistics warehouses and substations, adapts to the fire extinguishing needs of various flammable media, with strong compatibility.
Product Introduction
The balanced foam proportional mixing device is a new type of foam extinguishing device that provides foam mixed liquid to the foam fire fighting system.Its foam liquid can be continuously replenished during the working process of the system.With large liquid storage,high reliability and stability,it can greatly improve the fire extinguishing capacity of the system.In the foam fire protection system,the largescale foam fire protection project has put forward higher requirements for the supply source of foam mixture.The limited supply of foam solution of the traditional tank pressure foam proportioning device has become increasing ly incompatible with the requirements of modern largescale foam fire protection projects.PHP series balanced foam proportioning device is a new type of foam extinguishing device that provides foam mixture to foam fire fighting system.
