Since 1980 bfs has been exclusively producing single point watering systems for industrial batteries.

The basic element of the system is the bfs plug whose most important operational and flexibility characteristics are protected by key patents. The reliable, well tested mechanism inside the plug allows the battery to be filled with water at pressures ranging from 0.2 to 3.8 bars (3 - 53 psi). Only bfs offers such a unique performance and a variety of specialty plugs to meet specific needs of the battery industry.

30 years of research and development have shaped the technology of this system. The production and sales of over 7,000,000 plugs per year have made the company the global market leader in this field.

德國Batterie Fullungssysteme公司（BFS）自1980年成立至今，獨家生產工業電池單點加水系統。

       該系統的基礎要素是BFS加水旋塞，其操作功能及靈活性以獲得專利保護。旋塞內可靠、經驗證效果良好的結構使蓄電池在0.2-3.8巴（3-53磅/平方英尺）的壓力下加水。只有BFS公司可提供這種獨特性能、功能多樣的旋塞，極大滿足了蓄電池工業的特殊需要。

       BFS公司30多年的研發經驗促成了這項先進的系統工藝。公司旋塞的年生產及銷售量達700萬個，無疑是該領域市場的領導者。
