Plastic Super Mini Ring – Corrosion and Temperature Resistant for High Performance

A piece of plastic super mini ring on the blue background.
PSMR-01: Plastic super mini ring features high flux and low pressure drop.

Plastic Super Mini Ring, also called plastic flat ring, is an advanced products of plastic cascade mini ring. In the product design, the plastic super mini ring change the bevel edge of cascade mine ring into flat edge, which can make the structure uniform and improve the bulk density of random packing. Additional, the internal fingers of cascade ring are changed into internal curved rib to increase the packing strength.

The height-diameter ratio of plastic super mini ring is about 0.2–0.4, which has low pressure drop, high flux, excellent treating and mass transfer performance to be used in the water treatment applications.
