Static Mixer（High viscosity system）
https://www.dgchemtech.com/products/static-mixer/
The high-efficiency custom static mixer, designed without any moving parts, features a compact chemical static mixer design that saves floor space while minimizing maintenance costs. Its advanced static mixer function ensures optimal blending of fluids, and the industrial static mixer working principle relies on strategically engineered internal elements to achieve thorough mixing without mechanical agitation.

custom static mixer
An industrial static mixer is a precision constructed device that continuously mixes fluid ingredients without the use of moving parts. Industrial static mixers are typically used to mix liquid fluids, but they can also be used to mix gas streams such as static gas mixer, disperse gas into liquid, or blend immiscible liquids. The energy required for mixing is derived from pressure loss when fluids pass through the high pressure static mixer. As one of the top static mixer manufacturers and static mixer suppliers, DODGEN provide high quality industrial static mixer and custom static mixer.

Characteristics of Static Mixer
1
Compared with traditional mixing equipment, DODGEN industrial static mixer features simple process, compact structure, low energy consumption, low investment, large operation flexibility, good mixing performance, etc.

2
In the mixing process of liquid-liquid/liquid-gas/ liquid-solid/gas-gas and heat transfer process of emulsification/neutralization/absorption/extraction/reaction, traditional related equipment can be replaced by static mixing reactors.
