Quick Details
Plastic Tri-Pack is a hollow, spherical random packing designed to enhance gas-liquid contact in mass transfer applications. Its symmetrical geometry, composed of a network of ribs, struts, and drip rods, ensures maximum surface area and efficient liquid distribution. This structure prevents dry spots and channeling, improving overall scrubbing, absorption, and cooling tower performance.
High Void Space
Ensures low-pressure drop and efficient gas-liquid mixing.
Excellent Liquid Distribution
The unique open structure eliminates nesting and ensures uniform contact.
Superior Chemical & Corrosion Resistance
Available in PP, PE, PVC, PVDF, and other plastic materials, making it ideal for acidic and alkaline environments.
Lightweight & High Mechanical Strength
Injection-molded plastic construction provides durability and easy handling.
Self-Wetting Design
Reduces water retention and improves mass transfer efficiency.
