Reactors for Clean-In-Place (CIP), Sanitary Processing, and Hygienic Applications

Why CIP and Sanitary Design Require Specialized Batch Reactors

Sanitary reactors must minimize crevices, dead legs, and surface roughness while enabling thorough cleaning and sterilization. CIP systems reduce downtime, improve batch traceability, and support regulatory validation. Material selection, drainability, welding processes, and surface finishes directly influence product purity and compliance.

Frequently Asked Questions

Q: What materials are available for sanitary and CIP reactors?

A: We offer 304, 316, and 316L stainless steel, duplex stainless, Hastelloy, Inconel, and other alloys selected for hygienic and corrosion-resistant service.

Q: What sizes do you manufacture?

A: We manufacture sanitary reactors from pilot scale (50 gallons) through production scale (15,000+ gallons). Custom sizes are engineered to application requirements.

Q: What pressure and temperature ratings are available?

A: Standard designs support full vacuum to 5,000 psig and temperatures from cryogenic to 1,000°F. Ratings for SIP and thermal validation are also available.

Q: Do you provide engineering support for sanitary reactor specification?

A: Yes. Our engineering team supports specification of materials, finishes, welding, thermal control, instrumentation, and validation documentation.

Q: What is typical lead time for batch reactor manufacturing?

A: Lead times typically range from 16–24 weeks depending on size, materials, and complexity. Expedited schedules can be accommodated for urgent requirements.
