RVT Mixing and Process Engineering

What RVT Mixing and Process Engineering does

RVT Mixing and Process Engineering, legally RVT Rühr- und Verfahrenstechnik Maier & Richter GmbH, is a German specialty industrial equipment manufacturer founded in 1972 and headquartered in Töging am Inn, Bavaria. The company designs, produces, and services custom industrial agitators, mixer drives, stirrers, barrier pressure systems, and related accessories for chemical, pharmaceutical, food and beverage, biogas, petrochemical, wastewater, cosmetics, paint, and power generation industries. Its product portfolio spans more than 10 distinct drive platforms (including Direct Drive, Geared Mixer, Modular System, Chemical Standard, Magnetic Coupling, and Biogas variants) and 19+ stirrer geometries (propeller, axial flow turbine, blade, anchor, helical, dispersion disc, counter-current, DSQ, MIG, coaxial, and custom special constructions), all built around a modular system architecture that allows configuration from standard components for specific application requirements.

The technical scope spans extreme operating envelopes — viscosities up to 500,000 mPa·s, temperatures up to 600°C, and pressures up to 100 bar(g) — supported by in-house laboratory testing (viscosity and heat transfer in tanks from 20l to 1000l), vibration analysis, and flow simulation services. Differentiated features include the NRL/NRK Chemical Standard with divided disc clutch for quick seal replacement without agitator disassembly, magnetic coupling drives for hermetically sealed hazardous applications, and ATEX 2014/34/EU-certified equipment for Zone 0/T6 explosion protection. Quality is underpinned by DIN EN ISO 9001, HP0 welding, SCC safety certification, and FDA/GMP-compliant construction for pharmaceutical applications.

RVT generates revenue through direct enterprise sales of custom-configured agitator systems, ancillary services (laboratory testing, vibration analysis, flow simulations), and contract manufacturing (surface treatment/blasting). Pricing is not publicly disclosed; all sales require technical consultation for custom configuration. The company exports directly to industrial customers across 63 countries with no intermediary distributors, holding a Crefo-Cert creditworthiness certification for the fifth consecutive year. The company is privately held by founder/management and operates with approximately 75 employees.
