The Hiflow rings® are high performance tower packing. The strong lattice type provides high mechanical stability together with a very high void fraction. The low weight and the mechanical stability enable high packed heights without packing supports. High capacity of gas and liquid flow rates, extremely low pressure drop, very low wall flow and low sensitivity to pollution and fouling characterize the Hiflow-Rings®.
If Hiflow-Rings® replace conventional tower packing, then the flow rates in existent columns can be considerably increased or the energy consumption can be strongly reduced.

RMSR (RVT Metal Saddle Rings) offer big connected shapes for good wetting properties – resulting in better mass transfer at a smaller hydraulic diameter compared to Pallrings. Due to the open and modern grid structure, the pressure drop is much smaller.

Raflux-Rings (Pall rings) are standard tower packing. The open structure ensures a regular flow through the packing and lowers the pressure drop. Raflux-Rings are made of ceramics, plastics and metals. Raflux-Rings made from plastic or metal allow high gas velocities combined with a good separation efficiency.

Saddles ware standard tower packing. Besides the smooth surface, a good chemical resistance and a high stability of the single packing element is realized. Because of the simple geometry, a cheap prodution of saddles is possible. Ceramic saddles are suitable for destillation, especially while operating with acids. They are often used for heat storage in thermal oxidizers.

Balls are the simplest, regular formed packing elements. Packing with balls has a comparatively small surface per packed volume. Because of the low void fraction of the packing, the pressure drop is quite high.Balls are normally used as catalysts carrier and to smooth flows.

Cylindric rings are the simplest form of the standard tower packing. Production is possible out of almost any material. The surface of the rings is 30% higher than the surface of cylinders or of balls. The elements have a high mechanical stability and are normally used in applications, where they have been proved for years.

For wastewater treatment more and more biological processes are used. Special carriers are needed to support the growth of microbiological coatings. With the help of the chemical engineers, adapted packing elements for these processes have been developed, which in respect of surface, geometry and material correspond to the special demands. Random elements as well as structured sections are used in biological treatment plants. For moving bed processes with circulating carriers in a tank we provide the BIOFLOW carriers in different sizes.

Exlon-Rings belong to the group of the Raflux-packing elements. They are produced of PTFE and therefore they have an excellent resistance to chemicals and a good mechanical stability at high temperatures. This packing is produced in a newly developed manufacturing process.
