Our Innovation

First chemical glass invented by Caspar Pfaudler in Rochester, NY, USA.

A milestone in the development of chemical glasses: combined properties of the chemical resistance of ceramics and the strength of the metallic base.

Invention of a glass for polymerization processes: extremely smooth surface properties.

Today Pfaudler’s standard glass: enhanced physical characteristics through knowledge in development of high technology ceramics.

European Patent # EP 1231189: Invention of a glass with customized characteristics for the needs of the pharmaceutical industry.

Conductive and extremely durable. Conductive glass with the surface properties of WWG – World-Wide Glass.

Invention of a glass for simultaneously highly abrasive and corrosive processes: double resistance to abrasion with the same resistance to corrosion as WWG.

Pfaudler manufactures the first agitated Glasteel® reactor.

Invention of a cryogenic connection for a glass-lined, multi-piece agitator. No need for a dedicated opening for the agitation: assembly and maintenance of the agitator are fully made via the manhole.
Customized flyers created for specific process requirements. Initially, with typical turbines like CBT (curved blade impeller), TBF (turbofoil), PBT (pitched blade turbine), FBT (flat blade turbine), ANC (anchor).

Turbine for dramatically small residual quantities.
Agitating properties like CBT.

High-performance turbine for substances with higher viscosities.

High-performance gas dispersion turbine – about three (3) times higher vs. standard impeller.

High-performance turbine with opposing axial, shearing flow up to very high viscosity ranges.

4-blades turbine with Turbofoil characteristics in one piece. Suitable for smaller reactors or high number of agitation levels.

First in the world to achieve a 7-stage Cryo-Lock TBF (Turbofoil) agitator for a European customer for a mid-sized >10.000 Liters) glass-lined reactor.

Installation in the gas phase on Cryo-Lock shaft. Destroys the build-up of foam.

“Finger” baffle / “D” baffle / “H” baffle / “Beaver Tail” on stuffing box or flange mounted.

Invention of a multi-function Beaver Tail baffle allowing up to 6 functions on 1 reactor nozzle: baffling/ dip pipe/ temperature measurement/ sampling/ pH measurement/ corrosion monitoring.

Development of a new baffle shape for baffling effect approaching the “fully baffled” efficiency, providing an additional process nozzle retrofittable – for new reactors or retrofitting existing baffles.

C-baffle benefits transferred to AE type reactors - Retrofittable.

Invention of a temperature probe with fused-in technology within the glass temperature sensors. Compared to conventional glass-lined temperature measurements, extremely low response times of temperature change. No drifting, no aging.

First (and only) glass-lined liquid analysis technology: corrosion resistant glass formulation reacting to H+ ions in liquid media. Continuous monitoring of pH and/ or ORP. Installation either in reactors on tube carriers or in pipelines on ring carriers. Absolute and differential pH measurements.

First (and only) glass-lined capacitive probe. Ring probe for the detection of full or empty reactors or pipelines, pump protections. Detection of phase separations.

Invention of a continuous surface integrity monitoring device (glass-lined or PTFE). No more influence of electrically conductive internals or attachments, false alarms drastically reduced. In place / portable version for continuous/ planned downtime controls available.

First (and only) compact glass-lined pH probe designed for food, pharma and biotech industries: high mechanical resistance, anti-adhesive, in-line cleaning and sterilization up to 134°C.

Invention of a conductive glass-on-glass connection of CryCo-Lock turbine to CryCo-Lock shaft. Extends the corrosion monitoring capability to fully glassed CryCo-Lock turbines, without losing their assembly/disassembly properties.

Invention of a single tube sheet heat exchanger with replaceable glass-lined tubes and shell. Serves as liquid/ liquid heat exchanger, condenser; evaporator; reboiler.

Invention of a fused-in sight-glass in glass-lined steel carrier. No more gasket or bolted assembly. Improved safety, ease of cleaning, fracture proof. Base of the Glasslook glass-lined sight-glasses and manway covers family.

Invention of a quick-opening cover, glass-lined with O-Ring sealing. Includes fused-in Glasslook sight-glass, thumb screws for opening/closing without tooling. Base technology of the Fillook handhole and manway covers family.

Invention of a double tube sheet heat exchanger (patented connection): glass-lined tube sheets, shell and/or bonnets, silicon carbide tubes. High heat exchange performance, very compact. Corrosive media at tube, shell or both sides. Serves as liquid/ liquid heat exchanger; condenser; evaporator; economizer.

Revised Pfaudler gasket system for glass-lined nozzles. Improved in terms of corrosion resistance, compressibility, residual elasticity and mechanical strength. Certified to German standard TA-Luft.

First glass-lined reactor with halfpipe coils in 1973. In 2005, invention of the Pfaudler Clean Coil (PCC) manufacturing technology for scale-free inside coils, better heat transfer and extended lifetime of halfpipe coil reactors.

Air condensers are available in single and double versions. Air coolers can replace conventional water coolers in many chemical application processes. Such a conversion minimizes water consumption and saves money. This air cooler is a patented development by the WWU Münster, which NORMAG sells and uses exclusively. It only works with air and does not require water. This results in various advantages compared to conventional water coolers and air coolers from other manufacturers.

The triple holder pro enables an easy mounting of vessel and cover. Cover and vessel can be disassembled and assembled independently of each other. The exchange takes only seconds. The triple holder can be used to hold vessels up to a volume of 10 L and a size of DN 200.

Our new generation of shell and tube heat exchangers are equipped with an improved sealing system with special PTFE sealing rings developed exclusively for NORMAG. More common parts ensure a better spare parts storage and procurement. This standardization enables a faster delivery. Better assembly, maintenance and repair is possible due, to the new design of tube sheets and clamp rings.

The new modular construction system for agitators and agitating elements can be delivered faster, due to the higher standardization. The new size 25 mm replaces the size 18 mm and can be used for Ex areas up to 1/1, IIC, T3/4. For the Ex version, the Pt100 is always included in the scope of delivery. The connections for nitrogen and speed measurement are always available. Thanks to the new modular system, the standardized stirring heads can be exchanged with special tools. The new design of the shaft holder improves installation, maintenance and repair. The new magnetic stirrer coupling is designed for up to 12 Nm. In addition, we offer a magnetic coupling with an integrated Panasonic motor in a compact design, especially for laboratory applications.

Our Laboratory Mixer Settler has an extremely low dead volume and ensures a precise formation of the separation layer. The mixer cannot be influenced outside the resting zone. The unit is equipped with precisely adjustable drain valves. The Mixer Settler is also available in a rectangular tube version.

The Control Unit Pro2 is developed for the control and/or remote control of small or medium-sized laboratory systems. The visualization is possible on PC, laptop, tablet or smartphone. - Functions: control of aggregates, display of measured values, sequence control, recipe management, archiving, safety shutdowns
