Ceramic Pall Ring by German manufacturer VFF is a type of classic irregular nozzle developed on the basis of the Raschig ring. Usually, the nozzle has two holes with bends inside the cylinder wall. Each hole has five tongues that are bent to the axis of the ring. The ceramic Pall ring is completely identical in shape to the metal and plastic Pall rings. However, the number of holes and bends can vary depending on the height and diameter.
In general, the open surface of the nozzle should occupy 30% of the total cylindrical wall area. This design helps vapour and liquid to pass through the holes with ease, allowing full use of the inner ring surface for vapour and liquid separation. This also improves separation efficiency.
An important advantage of ceramic rings is their wear resistance. They do not react with the components of the raw alcohol/brag, and therefore such a nozzle with proper care will serve you for many years.
