The eTn VENTURI SCRUBBER is a device with excellent characteristics for dust and mist removal, and it has a proven track record of deliveries. By spraying the cleaning liquid from a large-diameter spray nozzle, it completely mixes the liquid and gas, demonstrating high dust collection efficiency. Additionally, because it uses a large-diameter spray nozzle, slurry-containing liquids can be reused in circulation, reducing the need for supplementary water. 【Features】 - Made of FRP as the structural material, it is lightweight, strong, and exhibits excellent corrosion resistance. - Sizes are standardized according to the processing air volume, allowing for shortened design and manufacturing lead times. - Three types (HV type, H type, V type) are available for the combination of the venturi tube and collector, enabling flexible layout options. *For more details, please contact us or download the catalog to view.

The treated gas is introduced through the gas inlet at the bottom of the main body, passes through the packing layer of Hi-Lex, and is discharged from the gas outlet at the top. Meanwhile, the absorbent liquid is sprayed from the top of the packing layer and comes into countercurrent contact with the treated gas. During this process, the target substances in the gas diffuse and dissolve into the liquid phase. 【Features】 ■ Efficient removal: Selection of high-performance packing material Hi-Lex suitable for design conditions ■ Pressure loss and low power costs: ■ Compact design: ■ Adaptable to various applications: Designed for use not only in absorption towers but also in dispersion towers, dehumidification towers, recovery towers, mist and dust removal towers, and gas cooling towers. *For more details, please contact us or download the catalog to view.

E-Techno guarantees high quality with reliable processing technology and equipment. TIG welding delivers excellent products by skilled welders with advanced techniques. Laser welding can handle materials as thin as 1.0mm. The issues of "thermal distortion" and "welding burn" that arise in thin plate welding are extremely minimal compared to TIG, ensuring the highest quality welding that can be described as "masterful." Additionally, since post-processing is almost unnecessary, it significantly contributes to shortening the process. *We are offering a free collection of technical case studies exclusively for inquiries from Ipros!
