Plastic Cascade Mini Ring for Rectification Towers

Plastic cascade mini ring adopts trumpet-shaped design with several windows open on the surface, which increases the mechanical strength of the whole ring. Being asymmetry, plastic cascade mini ring is increased the chance of directional delivery. It has features such as high void volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60 to 150. Compared with metal cascade mini ring, it has better corrosion resistance and lower costs.

This is a plastic cascade mini ring on the green background.

PCMR-01: Plastic cascade mini ring has several windows open on the surface.

There are multifarious plastic cascade mini ring in different sizes and colors.

PCMR-02: Plastic cascade mini ring has uniform gas-liquid contact.
