In last week’s blog post, we started walking through the key details in our Glass-Lined Reactor Specification Form to help you understand the information we need to prepare an accurate quote for your vessel. In this second installment of our three-part series, we’ll continue down the form, focusing on working conditions, environmental factors, and exterior design considerations.
To ensure your vessel is engineered for safe, reliable performance, we need a clear picture of the conditions it will face in operation. This includes both process parameters and jacket or coil requirements:
If you’re using a conventional jacket or HemiCoil, also list the intended heating/cooling media. This helps us determine if special zoning or circuit arrangements will be needed for optimal heat transfer and safety.
The environment where your reactor will be installed plays a big role in its design. Let us know if your site falls under any special hazard classifications, such as:
For example, if your unit is installed in an area with combustible dust hazards, an upgrade to an XP (explosion-proof) model with intrinsic safety features may be required. Providing this information upfront ensures your vessel is engineered for compliance and long-term safety.
While the inside of your reactor is where the chemistry happens, the exterior finish and components are just as important for durability and performance.
De Dietrich standard exterior finish:
If you prefer a different finish or color, simply provide the material of construction and the RAL color number.
De Dietrich’s model reactors come equipped with a standard set of nozzles on the top head. Before fabrication, additional nozzles can be incorporated into the design to better support specific process objectives.
The manway cover is available in several arrangements. The standard design features a dished cover with one sight glass. Alternatives include a flat cover with one fused sight glass and one quick easy-opening, or a flat cover with two fused sight glasses. To protect the glass lining, opening assistance can be added through a davit or spring assist, helping to prevent accidental drops or forceful closures.
For enhanced visibility, a halogen or fiber-optic lighting fixture can be installed onto the sight glass, allowing operators to perform visual inspections of the reactor’s contents. At the bottom of the vessel, the outlet nozzle is available in the standard design or with a pad flange.
Choosing a HemiCoil® jacket offers flexibility in creating multiple heating/cooling zones to improve heat transfer efficiency and prevent cross-contamination of media. Available arrangements include:

We can insulate the shell and bottom head in stainless steel, foam glass, mineral wool, or other materials, depending on your temperature and process needs.
Key considerations:
If you’re unsure which insulation material is best, our team can help guide the selection.
The right vessel support system depends on your reactor’s size and installation site. Options include:
We’ll work with you to determine the most stable support for your equipment.
In our final post of this series, we’ll explore mixing systems and peripheral equipment options that complete your reactor setup.
