Buss-SMS-Canzler GmbH
Butzbach · Düren · Erlangen · Pratteln (CH)New on Amplifa
Experts in thermal separation technology since 1919
Buss-SMS-Canzler GmbH develops and manufactures systems and apparatus for thermal separation processes: thin-film and short-path evaporators, static tubular evaporators, distillation columns, vertical and horizontal thin-film dryers (types CP and D), CFT dryers (Combined Fluidisation Technology) as well as thin-film processors (Filmtruder, Viscon) and large-volume single- and twin-shaft reactors (Reactotherm, Reasil, Reacom, Reamini) for polymers. Manufacturing takes place 100% in Butzbach (Germany) and Pratteln (Switzerland) and includes pressure vessel construction according to ASME U-Stamp, EN 13445, AD 2000, PED and ATEX. The company serves industries such as chemicals, polymers and fibres, oils and fats, environmental technology, pharmaceuticals, petrochemicals and the food industry, particularly for viscous, fouling and temperature-sensitive media. The main site in Butzbach houses manufacturing, mechanical engineering, purchasing, quality assurance and administration; branch offices exist in Düren, Erlangen and Pratteln (Switzerland) with a test centre featuring 20 pilot units.

Technologies and Manufacturing Standards
Thin-Film Evaporation
Vertical and horizontal thin-film evaporators (cylindrical/conical, co-/counter-current) for viscous, fouling and temperature-sensitive liquids.
Short-Path Evaporation
Short-path evaporators and distillation for low-pressure separations; the world's largest short-path evaporator plant in South-East Asia is equipped with seven SMS evaporators.
Horizontal Thin-Film Evaporator
Hygienic, GMP-compliant design for gentle continuous concentration in the pharmaceutical, cosmetics and food industries.
Thin-Film Drying (Types CP and D)
Vertical and horizontal contact dryers for solutions, suspensions, sludges, pastes, filter cakes and moist granulates, including toxic and explosive substances.
CFT Combined Fluidisation Technology
Combination of convective fluidised-bed and contact drying for sticky, crusting products such as tar and paint sludges, drilling muds, TDI recovery and soil contamination.
High-Viscosity Technology (Filmtruder, Viscon)
Thin-film processors for the production and processing of highly viscous products and polymers over wide viscosity and residence time ranges.
Large-Volume Reactors (Reactotherm, Reasil, Reacom, Reamini)
Single- and twin-shaft horizontal processors for reaction, degassing, mixing and recovery of polymeric and sticky products.
Pressure Vessel Construction
Manufacture of pressure vessels according to ASME U-Stamp, EN 13445, AD 2000, PED and ATEX, qualified according to DIN EN ISO 3834-2.
CFD Simulation
Computational Fluid Dynamics for visualising flow and mass transfer processes in thin-film evaporators for optimal apparatus design.
SMS Mechanical Seal
Intelligent mechanical seal with monitoring and predictive maintenance, retrofittable in up to 80% of existing thin-film evaporators.
