Industrial reactors are the heart of countless manufacturing processes across the chemical, pharmaceutical, food, and energy industries. These vessels are designed to safely contain and control chemical reactions under specific conditions of temperature, pressure, and mixing. Whether you’re polymerizing, fermenting, or blending raw materials, choosing the right reactor can significantly impact efficiency, product quality, and safety.
This guide will help you understand the most common types of industrial reactors, key features to consider before buying, and what to look for when purchasing a used reactor on Surplus Record.
What Is an Industrial Reactor?
An industrial reactor is a pressure-rated vessel designed to carry out controlled chemical reactions. It typically consists of a reaction chamber, an agitator for mixing, a heating or cooling jacket to regulate temperature, and controls to maintain reaction parameters.
Reactors can be built from a variety of materials—such as stainless steel, glass-lined steel, or carbon steel—depending on the process requirements and the nature of the chemicals involved. Their configurations and capacities vary widely, from small laboratory units to massive production-scale systems holding thousands of gallons.
Types of Industrial Reactors
There are several types of industrial reactors, each suited to specific processes and flow conditions:
- Batch Reactors: Used for reactions that occur in discrete batches. They offer flexibility for changing recipes and small production runs.
- Continuous Stirred-Tank Reactors (CSTRs): Operate continuously, maintaining a constant flow of reactants and products. Ideal for uniform mixing and steady-state reactions.
- Plug Flow Reactors (PFRs): Designed for continuous operation with reactants flowing through a cylindrical tube, ensuring minimal back-mixing. Common in petrochemical and polymer industries.
- Photochemical Reactors: Use light energy to drive reactions, typically in specialty chemical or pharmaceutical manufacturing.
- Bioreactors and Fermenters: Used in biotechnology and food production for cultivating cells, microorganisms, or enzymes under controlled conditions.
You can find all these reactor types listed on Surplus Record’s Reactor category.
Common Reactor Materials
Material selection is critical for ensuring chemical compatibility, durability, and safety:
- Stainless Steel Reactors: Corrosion-resistant and ideal for most chemical and food-grade applications. Easy to clean and maintain.
- Glass-Lined Reactors: Combine the strength of steel with the chemical resistance of glass, making them perfect for acids, solvents, and high-purity processes.
- Carbon Steel Reactors: Cost-effective for less corrosive applications or where internal coatings are applied.

Key Specifications to Consider
When evaluating reactors, pay close attention to the following specifications:
- Capacity: Usually measured in gallons or liters. Choose based on your production scale.
- Pressure and Temperature Ratings: Ensure the reactor can safely handle your process conditions.
- Agitator Type: Options include turbine, propeller, and anchor mixers—each designed for different viscosities and mixing requirements.
- Heating/Cooling System: Jacketed vessels and internal coils provide temperature control.
- Lining or Coating: Glass, rubber, or PTFE linings offer corrosion protection for aggressive chemicals.
- Certifications: Look for ASME code stamps or other relevant compliance marks for pressure vessels.

Applications of Industrial Reactors
Industrial reactors play a key role in a wide range of processes and industries:
- Chemical Processing: Synthesis, polymerization, and oxidation reactions.
- Pharmaceutical Manufacturing: Formulation, crystallization, and fermentation.
- Food & Beverage: Mixing, pasteurization, and enzymatic reactions.
- Petrochemical Production: Refining and catalytic reactions.
- Biotechnology: Cell culture and enzyme production.
Each application demands a reactor with the right materials, controls, and design for optimal performance and safety.
Tips for Buying a Used Reactor
Buying a used reactor can save significant costs, but inspection is key. Before purchasing:
- Verify ASME certification and safety compliance.
- Check vessel walls and welds for corrosion, pitting, or cracks.
- Test agitator bearings and seals.
- Ensure jacket and coils are leak-free.
- Confirm control panels and sensors function properly.
- Review maintenance logs or test certificates when available.
Buying from trusted dealers on Surplus Record helps ensure quality and reliability, with many sellers offering inspection or testing prior to shipment.
