The Vertical Foam Bladder Tank is a steel pressure vessel fitted with an internal bladder that stores foam concentrate. When the pressurized water flow of the fire protection system passes through this device, the pressure proportional mixer diverts it proportionally. A small portion of the water enters the interlayer of the foam concentrate storage tank with a rubber bladder, compressing the bladder and displacing the foam concentrate. This foam concentrate then mixes with the fire protection water within the pressure proportional mixer to form a foam mixture of the corresponding proportion. The foam mixture is subsequently transported through piping to the foam discharging device, directly performing fire extinguishment in the protected area.

To meet the diverse needs of customers in different application scenarios for fire monitor flow rate and range, the R&D department of Ningbo Plent Machinery Co., Ltd. recently launched an ultra-large fire monitor. This product is specifically designed for fire rescue scenarios with big flow rate requirements.

To meet the diverse needs of customers in different application scenarios regarding the flow rate and range of fire monitors, the R&D department of Ningbo Plent Machinery Co., Ltd. recently released a new 475LPM nozzle fire monitor. This product is specifically designed for firefighting and rescue scenarios with low flow rate requirements.

At the successfully concluded China Fire 2025, PLENT & SXFIREPRO teams made a remarkable appearance with the newly launched ultra-large fire monitor and auto tracking fire monitor, becoming a highlight of the event. During the exhibition, our team engaged in in-depth exchanges with friends and partners from around the world, reaching preliminary cooperation agreements and returning with a successful conclusion.

A delegation of Russian clients and fire department leaders visited our company for a factory audit. During the visit, they conducted rigorous tests on key performance metrics of products such as the auto-tracking monitor, foam inductor, and foam tank—including flow rate, range, extinguishing speed, and mixing ratio accuracy. Thanks to the collaborative efforts of our entire team, all relevant technical documentation has successfully passed the audit.

​Thanks to the long-term support of our customers, we are pleased that many of you have already confirmed your attendance. To ensure everyone has all the necessary information, we would like to extend a renewed invitation to you and look forward to meeting and discussing with you at the exhibition.
