Equipment for Mixing and Reaction
Since 1990, Nagamori has been engaged in the design and manufacturing of agitators and reactors. It not only provides impeller selection but also optimizes and scales up production according to different operating conditions. The integrated design effectively resolves the mismatch between agitator and reactor while reducing on-site assembly work for customers. Related equipment is widely used in the chemical, metallurgical, pharmaceutical, and electronics industries.

Hydrogenation Reactor
Homogeneous liquid phase: Achieving uniform concentration and temperature within the reactor through agitation.

1. The reactor is resistant to high temperature and high pressure, enabling hydrogenation reactions between hydrogen and raw materials.

2. It is equipped with mechanical seals or magnetic drive seals to minimize leakage.

3. The design is customized to match various process parameters.

4. Manufactured from 316L, 904L, C22, duplex steel, and other special materials, the reactor offers excellent resistance to corrosion, high pressure, and extreme temperatures.

Polymerizer equipped with auxilliary system

A complete functional unit integrated with a sealing system, control system, steel structure, and more.

Autoclave
High temperature and high pressure, continuous operation, multi-chamber mixing.

1. Operating temperature of 260°C;

2. High pressure of 5.5 MPa;

3. Capable of continuous operation for up to 330 days;

4. Multi-chamber design with agitation at different stages;

5. Ensures uniform suspension and dispersion of the slurry.

Catalytic reactor
Specifically designed for gas-liquid-solid multiphase catalytic reactions, featuring a dual-agitation system

1. Specifically designed for gas-liquid-solid multiphase catalytic reactions.

2. Dual-agitation system as the core.

3. Achieves a fully mixed flow state.

4. Upper and lower impeller speeds or types can be independently adjusted according to process requirements.
