Plastic Cascade Mini Ring

Plastic cascade mini ring is a type of high-performance plastic random packing, which adopts trumpet-shaped design with several windows open on the surface, which increases the mechanical strength of the whole ring.  It changes the traditional equal length and diameter structure, and also changes the cone-shaped flanging at one edge. This special structure has shortened distance which gas passing through wall's out surface, but also reduced the resistance when air passing through bed layer and increased voidage.

It has a low aspect ratio, good corrosion resistance, good separation effect. Plastic cascade mini-rings have a greater capacity and higher efficiency than plastic Pall rings.

Feature

Feature

Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.

Feature

High void ratio and low pressure drop

Feature

Open structure and preferred vertical axis orientation

Feature

More easily flushed through the bed by the liquid

Feature

Low aspect ratio increases capacity and reduces pressure drop

Application

Characterized by low aspect ratio, good corrosion resistance and excellent separation effect, plastic cascade mini ring is widely used in the packing towers in petroleum industry, chemical industry, alkali-chloride industry, coal gas industry and environmental protection, etc.
