RA Series Glasteel® Reactors

Long-recognized standard in glassed-steel reactors for the chemical process indus-tries. Top-quality design and construction contribute to long, dependable service life.

Choose from the full line of Pfaudler RA Series Glasteel reactors, with models ranging in size from 300 to 15,000 gallons. All offer the familiar RA features, the same built-inruggedness and reliability the industry has depended on for decades.

Versatile Cryo-Lock optionsSomething new has been added to give RA reactors a flexibility never before possible. The exclusive, Pfaudler Cryo-Lock agitator design provides a wide choice of impeller configurations to answer changing mixing requirements.

The interchangeable Cryo-Lock impellers are quickly replaced inside the vessel, result-ing in substantial savings in downtime costs.

Moreover, the variety of impeller designs available can handle every mixing task from simple blending to emulsification. This means that a quick changeover of impeller and baffle can reconfigure your RA reactor for an entirely different process.

Standard Cryo-Lock impeller configurations are used in RA reactors sized from 300 to 4000 gallons. For larger reactors, Pfaudler fabricates impellers on a custom basis.

Easy, inexpensive modificationThe standard models of RA Series reactors, detailed here, are based on thoroughlyproven engineering designs. In many cases, the basic design can be modified to meetyour specific needs.

The top head layouts shown are typical, suggested layouts. During fabrication, openingscan be omitted, resized or moved to suit your process and your piping arrangement.

• Heavy-duty forged nozzles minimize distortion, reduce time-consuming gasket shimming.

• Split backing flanges, Class 150, supplied with all nozzles. Flanges rated Class 300 also available.

• 3000-psi series jacket couplings, baffled to prevent jacket media from impinging directly on vessel wall. Flanged jacket connections are optional.

• Conventional jacket equipped with agitating nozzles provides optimum liquid circulation in jacket. Optional half-pipe jacket can be either parallel-path or zoned.

• Adjustable pipe leg supports are supplied on 300 through 400 gallon. Side supports are optional.

Improve Efficiency and Reduce Maintenance

• Special formula glass lining, fused to steel substrate, is highly corrosion resistant and chemically inert to nearly all substances. Ideal environment for processing ultra-pure products.

• Smooth Glasteel surface also resists adherence by viscous or sticky materials. Cleans easily.

• Cryo-Lock agitator features a glass-to-glass interference fit between impeller bore and shaft. Provides off-the-shelf interchangeability.

• Cryogenic cooling joins or separates impeller and shaft for fast, easy, reliable installation and maintenance.

• Fin baffle position is close to sidewall to promote better top to bottom turnover.
