316L Stainless Steel Jacketed Stirred Tank Reactor 500L-10000L for Resin Polymer Adhesive Chemical Synthesis Production

Jacketed Stirred Reactors for Resin, Polymer, and Adhesive Production

We build 316L stainless steel jacketed stirred tank reactors in sizes from 500L to 10,000L, designed for chemical synthesis processes where material purity, thermal control, and mixing consistency matter. These vessels are used in resin and polymer production, adhesive manufacturing, and a range of batch chemical operations.

The 316L grade gives you better corrosion resistance than 304, especially when processing formulations with chlorides, organic acids, or other aggressive components. We weld with full penetration and back-purge argon on all wetted seams, then passivate the interior surfaces. Internal polishing is available to Ra 0.4µm or finer—critical if you\’re running adhesive or polymer recipes where residue buildup creates contamination risks between batches.

The outer jacket is split into zones for more predictable heating and cooling. You choose the heat transfer fluid based on your process temperature range: steam for high-temp cure cycles, thermal oil for precise mid-range control, or chilled water/glycol for exothermic reactions that need fast cooling response. A well-designed jacket minimizes hot spots, which matters when you\’re dealing with viscous resins that don\’t move heat easily.

Our standard agitator is a pitched-blade turbine, but we regularly supply anchor, helical ribbon, and dual-shaft combinations. If your product hits high viscosity at certain stages, a scraper or close-clearance design prevents buildup on the vessel wall and improves heat transfer. We also build in baffles where axial flow is needed.

Sealing options depend on your operating pressure and whether you\’re handling solvents or toxic monomers. We offer mechanical seals, single or double, with flush plans, as well as magnetic drives for fully contained operation.

Choosing the Right Configuration

Before you request a quote, define your process parameters clearly. What exactly are you mixing—a low-viscosity solvent-based adhesive or a high-solids resin that thickens as the reaction progresses? What\’s your batch size and working volume? What temperature will the process reach, and will it run under pressure or vacuum?

These details determine the agitator type, motor power, jacket design, and whether you need a vacuum-rated vessel with a specialized seal. If you\’re handling materials that leave residues, plan for clean-in-place spray balls and a larger manway. If your reaction is strongly exothermic, make sure the jacket and cooling loop are sized for that peak load.

Frequently Asked Questions

Q: Can I use this reactor for vacuum operation?
Yes, we can design for full vacuum service. This requires reinforced shell thickness and appropriate nozzle and seal selection. Specify your vacuum level and whether you\’ll be pulling solvent vapors through a condenser.

Q: What\’s the difference between a dimple jacket and a half-pipe coil?
Dimple jackets are lighter and cheaper, good for moderate pressures and heat transfer rates. Half-pipe coils handle higher jacket pressures and give more uniform temperature distribution, which we often recommend for polymer processes requiring tight thermal control.

Q: How do I clean between batches?
For water-soluble products, spray balls with CIP are usually enough. For resin or adhesive residues, you may need a solvent wash or manual cleaning through the manway. We can add a dedicated cleaning port and angled nozzles to make this easier.

Q: What about explosion-proof requirements?
If you\’re processing solvents, we can supply explosion-proof motors and control panels, along with proper grounding and venting connections. This is a common requirement in adhesive and coating plants.
