Overview
The Open Type Glass Lined Reactor, professionally designated as the K-Series, is a premier pressure vessel designed for versatile chemical processing. Characterized by its two-piece “split-body” construction, this reactor consists of a main vessel body and a completely removable top cover, securely joined by a heavy-duty flange system and high-strength clamps.
Unlike closed-type models, the K-Series is engineered for processes that demand maximum internal access. Whether your application involves frequent material changes requiring thorough cleaning or the use of large-diameter agitators, the Open Type design provides the operational flexibility needed for medium-scale industrial production up to 5000L.

Working Principle
The working principle of the K-Series reactor relies on its modular flange design. By separating the cover from the body, the reactor allows for the installation of heavy-duty, wide-sweep agitators that cannot fit through standard manholes. During operation, the motor drives the agitator to create a uniform mixing pattern, while the jacket (filled with steam or thermal oil) facilitates precise heat exchange through the glass-lined wall. The flanged connection ensures a reliable seal even under vacuum or moderate pressure, while allowing the entire “lid” to be lifted for complete vessel inspection.
The internal glass lining is fired at high temperatures to form a durable, corrosion-resistant protective layer, ensuring long service life under harsh chemical conditions.
Key Features
-
Unmatched Maintenance Access: The removable flanged cover allows for 100% access to the vessel interior, significantly reducing downtime during inspection or glass-lining repairs.
-
Large Agitator Compatibility: Specifically designed to accommodate Anchor and Frame-type agitators, ensuring high-torque mixing for high-viscosity fluids.
-
Superior Corrosion Resistance: Our proprietary glass-lining technology creates a non-stick, chemically inert surface that protects against aggressive acids and alkalis.
-
Flexible Scaling: With a maximum capacity of 5000L, the K-Series is the industrial “sweet spot” for pilot plants and specialty chemical batching.
-
Robust Sealing Integrity: Precision-machined flanges and specialized gaskets ensure a leak-proof environment for sensitive chemical reactions.
Applications
The K-Series is the ideal solution for industries requiring frequent batch turnovers and high mixing efficiency:
-
Fine Chemicals: Processing of resins, polymers, and adhesives that require high-viscosity agitation.
-
Pesticides & Agrochemicals: Synthesis of corrosive intermediates where easy cleaning is mandatory to prevent cross-contamination.
-
Dyes & Pigments: Applications involving heavy slurries that benefit from the wide-sweep cleaning of anchor agitators.
-
Specialized Labs & Pilot Plants: Where the flexibility to swap agitators or modify internal setups is a priority.
Frequently Asked Questions (FAQ)
Q1: What is the main difference between an Open Type (K-Series) and a Closed Type (F-Series) reactor?
A: The primary difference lies in the top cover structure. The Open Type (K-Series) has a completely removable flanged cover, allowing for easy cleaning and the installation of large agitators like anchor or frame types. The Closed Type (F-Series) is a one-piece welded vessel designed for higher pressure and larger capacities (above 5000L).
Q2: Why is the capacity of the Open Type Glass Lined Reactor usually limited to 5000L?
A: To ensure absolute sealing integrity. As the vessel diameter increases beyond 5000L, the large flange required for an Open Type design becomes more susceptible to thermal expansion and pressure stress. For applications requiring volumes over 5000L, we recommend our F-Series Closed Type design to guarantee safety and vacuum stability.
Q3: Which agitator is most suitable for an Open Type reactor?
A: The Open Type design is specifically optimized for high-viscosity mixing. Because the lid can be removed, we can install wide-sweep Anchor and Frame agitators. These agitators scrape the internal glass-lined walls to improve heat transfer and prevent material buildup, which is difficult to achieve with the narrow manholes of closed reactors.
Q4: How is the glass lining (enamel) applied in VANVEO reactors?
A: At VANVEO, we follow a rigorous multi-stage glazing process. We use high-quality enamel powder applied via cold spraying technology. Each vessel undergoes approximately 8 rounds of spraying and firing, including specialized ground coats and multiple cover coats. This ensures a dense, pinhole-free glass layer that is fused to the steel for maximum chemical resistance.
Q5: How do you prevent the glass lining from cracking during sea freight?
A: We use a multi-layer reinforced fixation system for international shipping. Each reactor is mounted on a heavy-duty wooden pallet or a custom steel frame. The equipment is then cross-secured using steel wire ropes and timber bracing to eliminate any movement inside the container. This rigid support system effectively absorbs the mechanical shocks of ocean transit, ensuring your glass-lined investment arrives in factory-perfect condition.
