Raflux Ring - Random packings

Name: Raflux Ring - Random packings | Hansa Engineering
Availability: InStock

Raflux rings are a second generation tower packing which are generally classified as a standard tower packing. The Raflux ring has evolved from the cylindrical ring.

The Raflux Ring has an open structure compared to the cylindrical ring, which ensures a regular flow through the packing, reducing the pressure drop whilst maintaining the same surface area of the packing.
