High Performance with RVT Process Equipment Tower Packings
Whatever a system, mass transfer, heat transfer or biological, selecting a tower packing that optimizes the total gas to liquid interface with a low pressure drop is sought after for optimal performance. RVT’s tower packings meet these requirements. Available in a multitude of geometrical configurations as well as materials of construction, RVT Process Equipment provides a packing for almost every application.
Hiflow® Rings The Hiflow Ring is a 3rd generation high performance tower packing which provides an optimal design of high mechanical stability, void fraction and superior mass transfer. When a higher performance packing is required the Hiflow Ring can handle higher capacities of gas and/or liquid than that of conventional and other high performance packings, due to its open structure
and optimized design without sacrificing mass transfer. The mechanical stability and light weight nature of the Hiflow Ring make them ideal for high packed beds without the need for intermediate support grids, and due to the exceptional mechanical design the tendency for the liquid to migrate to the columns wall is minimized.

Raflux Rings Raflux Rings are a second generation tower packing which are generally classified as a standard tower packing. The next evolution to the cylindrical ring, the Raflux Ring has an open structure which reduces the pressure drop while maintaining the same surface area of the packing. Raflux Rings are available in a variety of sizes and materials (ceramic, plastic and metal). Known for its balance between mass transfer and pressure drop, Raflux Rings remain one of the most commonly used tower packings in industry. Raflux Rings type/ size

RMSR – RVT Metal Saddle Rings The RMSR (RVT Metal Saddle Ring) is one of the industry’s highest performance metal random tower packing which has an excellent mass transfer efficiency while maintaining a very low pressure drop. Although, it has an open structure, the design provides a high mechanical
stability able to withstand heavy liquid loading and extremely tall bed heights. Additionally the RMSR tower packing generates a uniformly packed bed inside the column ensuring optimal gas-liquid interaction and minimal channeling.

HiDur™ Inert Ceramic Balls Balls are the simplest design of all packings. Refineries and petrochemical plants are the primary users for balls as they are using them as catalyst support media. While balls can technically be used for packed bed applications they are rarely utilized as they have an extremely high pressure drop with relatively low surface area.

Saddles Saddles are classified as standard tower packing. Even though high performance tower packings are leading the way in terms of superior performance the saddle tower packing is still utilized in many applications due to its proven performance and cost effectiveness.
Ceramic saddles are still the number one selling ceramic product in acid industries as they have excellent mechanical and corrosion properties at unparalleled low costs. A further application is the utilization in regenerative thermal oxidizers (RTO).

Support Systems In acid applications, due to the agressive nature of the gaseous and liquid components being handled, support plates of special design, manufactured from acid resistant ceramic materials, are used almost exclusively. Depending on your specific needs, the appropriate support plate can be supplied.
