Product description

Stainless Steel Atmospheric Reactors for Process Flexibility

Atmospheric reactors handle a wide range of liquid-phase reactions where pressure control is not the primary concern. We build these vessels for processors who need reliable mixing, consistent heat transfer, and straightforward cleaning between batches. Whether you\’re running esterification, neutralization, polymerization, or simple blending, the vessel design directly affects your yield and cycle time.

The wetted parts are fabricated from 304 or 316L stainless steel, depending on your feed chemistry. 316L is the safer choice when chlorides or acidic media are present. We weld with full penetration and passivate the surfaces after fabrication. Interior welds are ground flush, and the product contact area can be polished to Ra 0.4 µm if your process demands it. For less critical applications, a 2B mill finish with a 150-grit polish is sufficient and more economical.

Mixing and Heat Transfer Considerations

Efficient mixing in an atmospheric reactor comes from matching the agitator to the fluid. We fit anchor, paddle, or turbine impellers based on viscosity and solids content. A PTFE or mechanical seal at the shaft entry prevents leakage and contamination. The jacket—either dimple or half-pipe coil—provides heating or cooling via steam, thermal oil, or chilled water. Baffles are installed when turbulent mixing is required.

Typical Applications

These reactors are common in specialty chemical plants, resin and adhesive production, and cosmetic batch manufacturing. They also appear in pharmaceutical intermediate synthesis where the process runs at ambient pressure. You can add a reflux condenser, addition funnel, or sampling port through the top nozzles. Clean-in-place spray balls are an option for faster turnaround.

FAQ

Q: Can I run a vacuum process in an atmospheric reactor?
A: Not without modifications. Vacuum service requires a pressure vessel design and different seal selection. Tell us your actual operating pressure.

Q: What if my material is corrosive?
A: Send us the chemical composition and concentration. We\’ll advise on the right grade of stainless steel or a lining option.

Q: How do I choose the right agitator?
A: It depends on viscosity and whether you need shear. Anchors work for high-viscosity pastes; turbines are better for low-viscosity mixing and suspension.

Before you ask for pricing, prepare these details: the material you process, its concentration and viscosity, the working volume per batch, operating temperature, and whether you need heating or cooling. Also specify any cleaning or seal requirements. Send these to our engineering team, and we\’ll recommend the right configuration and provide a firm quote.

Customer Review

We ordered a complete peanut butter processing line, and overall we’ve been very happy with it. The equipment arrived well packed and everything was installed and tested without major issues. The line runs smoothly, and the mixing and processing have been consistent. Our peanut butter comes out with a good texture, and the equipment is not difficult for our operators to use and clean. The support from the supplier was also helpful during setup. So far, it has been a good investment for our production.
