About RVT Process Equipment
RVT Process Equipment GmbH is a medium-sized company based in Marktrodach (Kronach district, Bavaria) that manufactures components and systems for mass and heat transfer processes. The portfolio comprises random packing elements made of ceramic, plastic and metal (including Raflux rings and Hiflow® saddles), structured packings, column internals such as support grids, liquid distributors and droplet separators, mass transfer trays and complete columns. In plant engineering, the company delivers turnkey systems for exhaust gas and waste air purification, ammonia recovery by stripping, residue and silane combustion, and industrial burner systems, including steel construction, piping, electrical/instrumentation systems (EMSR), process control (PLC) and safety engineering. Production ranges from smallest quantities for laboratory tests to turnkey plants on an industrial scale. Customers include companies such as Linde Engineering, BASF, Evonik, Bayer, Solvay, TechnipFMC, thyssenkrupp and Dow; products are delivered worldwide via subsidiaries in Knoxville (USA) and Kunshan (China). RVT is one of the leading European suppliers of packings, column internals and mass transfer trays.

Materials and Processes
Stoneware (ceramic)
Used for saddles and Raflux rings, particularly suitable for distillation tasks in acid technology and as heat storage media in thermal waste air purification systems.
Polypropylene (PP, PPH)
Standard material for plastic packing elements such as Raflux rings in chemically demanding applications.
Polyethylene (PE)
Material option for random packing elements made of plastic.
PVC / C-PVC
Material for packing elements and wire mesh separators with chemical resistance.
PVDF
Highly resistant thermoplastic for demanding chemical separation tasks.
PFA, ECTFE, ETFE
Fluoropolymer materials for wire mesh separators handling aggressive media.
Stainless steel 1.4301 (AISI 304)
Reference material for metallic Raflux rings and column internals.
Carbon steel
Cost-effective material option for metallic packing elements and steel construction.
Hastelloy
High-alloy alloy for corrosive applications in packing elements and separators.
Titanium
For metallic packing elements and separators with extremely corrosive media.
