The BNX capping head is an updated version of the BVK head, developed by Bericap seven years ago.
Like the previous generation product, the new BNX head is equipped with a hysteresis coupling. This is an electro-magnetic clutch that provides a consistent application torque independent of the head speed, which varies with different bottle types and sizes.
According to Bericap, a hysteresis-based system ensures that caps are secured more consistently so that consumers do not come across bottles that are a struggle to open or caps that are too loosely applied.
But the company claims that the new BNX capping head has gone further, with a hysteresis system that is more consistent than the previous version. Bericap said this is because it provides an application torque in a narrower range.
In addition, the German beverage cap specialist said the BNX offers improved handling and flexibility.
The height of the BNX is shorter so the head can be built into more filling systems and the application torque can be adjusted simply by hand, without any special tooling.
Another area of improvement with the BNX is hygiene. Bericap told BeverageDaily.com: “The capping head was modified in order to fulfill even higher requirements on hygienic standards.” The company said the new head is liquid tight to prevent washing down of any lubricants.
Bericap is one of the biggest manufacturers of caps and closures in the world with 20 factories spread across 18 countries.
