Overview
The Closed Type Glass Lined Reactor (also known as Monoblock Type) is a one-piece glass-lined steel vessel with an integrated agitator. Designed for maximum safety, the top head’s main opening is restricted to less than half of the vessel diameter. This specialized geometry allows for significantly higher pressure ratings and superior thermal shock resistance, making it the preferred choice for hazardous chemical synthesis and large-scale industrial production.
As a professional glass lined reactor manufacturer, VANVEO provides customized closed type reactor solutions for pharmaceutical, fine chemical, and petrochemical industries. We support multiple pressure vessel standards, customized agitator systems, and export-oriented engineering services for global industrial projects.

Working Principle
Heating and cooling of the Closed Type Glass Lined Reactor is achieved through a U-type or Semi-coil jacket using steam, water, or heat transfer oil. The agitator, powered by a flameproof AC motor and vertical reducer, ensures uniform mixing. For high-pressure operations, we utilize advanced Double Mechanical Seals or Magnetic Seals to guarantee zero leakage, even when handling volatile organic solvents and strong acids.
Key Features
Enhanced Structural Strength: The “Monoblock” design allows for a more rigid vessel head, capable of sustaining higher agitation torques and internal pressures.
Diverse Agitator Options: Choose from Propeller, Impeller, Paddle, or customized combinations. The Q Series supports removable blade designs (including anchor type).
Strict Quality Testing: Every unit undergoes a Hydraulic Test at 1.2 times the design pressure for both the jacket and vessel to ensure structural integrity.
Versatile Medium Compatibility: Excellent resistance to organic/inorganic acids and weak alkalis (excluding HF, fluorine-ion media, and specific high-temp phosphoric acid).
Safety Advantages of Closed Type Glass Lined Reactor
The closed type monoblock structure provides enhanced operational safety for high-pressure and hazardous chemical processes. By minimizing large-diameter openings on the vessel head, the reactor achieves improved structural rigidity and sealing reliability.
Combined with advanced sealing systems, the closed type design effectively reduces the risk of leakage when processing volatile solvents, corrosive acids, and toxic intermediates under vacuum or pressure conditions.
Applications
API Pharmaceutical Production: High-purity reactions requiring deep vacuum and strict sealing.
Fine Chemical Synthesis: Processing volatile organic acids and solvents.
Petrochemical Processing: Large-scale reactions up to 40,000L under high pressure.
Dye & Pesticide Manufacturing: Safe handling of corrosive and toxic intermediate products.

FAQ
Q1: What is the difference between F, Q, and CE series closed reactors?
A: The F/CE series have a smaller main opening on the top head for easier maintenance, while the Q series (Monoblock) maximizes strength by removing the large opening entirely. The CE series specifically follows DIN 28136 standards with a wider temperature range (-25°C to 230°C).
Q2: Which seal should I choose for 1.0 MPa pressure?
A: For high-pressure applications (0.6 – 1.0 MPa), we recommend a Double Mechanical Seal or an optional Magnetic Seal to ensure a perfect airtight environment and prevent hazardous leaks.
Q3: Can VANVEO customize the jacket type?
A: Yes. We offer both standard U-Type Jackets and Semi-coil Jackets (Limpet Coil) depending on your heat transfer requirements and the heating medium used (steam vs. oil).
Q4: What industries commonly use Closed Type Glass Lined Reactors?
A: Closed type glass lined reactors are widely used in pharmaceutical manufacturing, petrochemical processing, agrochemical production, dye intermediates, and fine chemical synthesis where high-pressure operation and reliable sealing performance are required.
