ASME SS316L Reactor Tank 50-10000L Internal Coil Heating PLC OEM/ODM

We build this reactor tank for process lines that demand consistent thermal control and cleanable wetted surfaces. The vessel is constructed from SS316L, with an internal coil for direct heating of the batch. Capacity ranges from 50 to 10,000 liters, so the same design philosophy scales from pilot trials to full production.

The shell and coil are fabricated from 316L stainless steel — chosen for its resistance to chlorides, acids, and general corrosion in chemical, pharmaceutical, and food environments. All welds are fully penetrated and ground smooth. Interior surfaces are electropolished to Ra ≤ 0.4 µm as standard, which simplifies cleaning and reduces product adhesion. For hygiene-critical applications, we can also provide a finer finish or certify the surface roughness.

Heating is delivered through an internal coil that carries steam, hot water, or thermal oil. This design maximizes heat transfer area and reduces thermal gradient inside the vessel — important when processing shear-sensitive or temperature-sensitive products. Cooling can be added through a separate jacket or an additional coil, depending on your process needs. The entire system is controlled by a PLC that manages temperature ramps, hold times, and agitation speed. We can integrate your existing control architecture or supply a complete skid.

This reactor is used in industries such as specialty chemical synthesis, pharmaceutical intermediate production, food emulsification, cosmetics blending, and polymer preparation. Typical applications include resin cooking, soap saponification, fermentation broth heating, and pigment dispersion. The vessel handles both low-viscosity liquids and slurries with moderate solid content, provided the agitator is selected correctly.

We offer several agitator options — anchor, paddle, turbine, or helical ribbon — matched to your mixing requirements. The shaft seal is either a single or double mechanical seal, or a magnetic drive for zero-emission operation. For vacuum or pressure service, the vessel can be designed to ASME Section VIII Div. 1 or PED, with a design pressure up to 10 bar (customizable). The standard working pressure is atmospheric, but we can reinforce the shell for your specific conditions.

Below is a summary of the standard configuration — note that every item is adjustable based on your process data.

FAQ — What buyers actually ask

Q: Can I use this for a corrosive chemical like hydrochloric acid?
A: SS316L handles dilute HCl at low temperatures, but concentrated acid will attack it. For aggressive media, we recommend a different alloy or a glass-lined vessel. Send us the chemical concentration and temperature, and we will advise the correct material.

Q: How do I choose between an internal coil and a jacket?
A: Internal coils give faster heating but can interfere with mixing. Jackets are easier to clean but have lower heat transfer area. We often combine both — coil for heating, jacket for cooling. Tell us your heating rate and temperature uniformity needs.

Q: What about cleaning in place (CIP)?
A: The vessel is designed with no dead zones, and the coil is pitched for drainage. Spray balls can be installed. If you require full CIP/SIP, we will adjust the nozzle positions and surface finish.

Q: Is this vessel suitable for vacuum operation?
A: Yes, if we reinforce the shell and use a vacuum-rated seal. The design pressure must be specified. For full vacuum, we typically use a thicker shell and a double mechanical seal.

Q: Can you provide OEM/ODM with our branding?
A: Absolutely. We produce vessels under your brand, including nameplates, manuals, and control panels. We are flexible on documentation and certification.

Getting the right configuration

Before requesting a quote, prepare the following details: the exact product and its chemical composition, batch size and working volume, operating and design temperatures, pressure (atmospheric, positive, or vacuum), viscosity and solids content, heating/cooling medium available on site, required mixing intensity, and any cleaning or regulatory standards (ASME, cGMP, ATEX). With this information, our engineers can specify the correct wall thickness, agitator type, seal arrangement, and control scheme.

Send us your process parameters — we will respond with a technical proposal and a budget figure. No generic quotes, only a vessel built around your process.
