Perfect pin geometry

A rotating magnetic field oscillates the pins which subsequently enables them to gently remove the superficial deposits mechanically. The rotating pins warm the cleaning bath up to approx. 45°C / 113°F, which subsequently intensifies the effect of the chemical reaction.

The pins are made from an acid resistant alloy, and their shape, which is not possible to see with the naked eye, is designed for highest possible effectiveness and durability. Renfert pins are cut exactly at a right angle. This makes them highly efficient, and at the same time gentle to the object’s surface.
