Пластиковые пакеты Tri-pack PP PVDF CPVC

In traditional mass transfer theory, larger surface areas often suggest higher efficiency. However, excessive surface area may lead to gas-liquid obstruction, pressure drop, and packing channel blocking. Plastic Tri-packs were designed to avoid these issues. Their design ensures that liquid uniformly wets the entire surface, preventing dry spots and ensuring optimal performance under various operating conditions. Plastic Tri-packs are widely recognized for their lightweight structure, large void space, and excellent hydrophilic surface. The absence of corners and valleys in their design reduces wall flow, ensuring better distribution and dispersion of gas and liquid phases.

Plastic Tri-packs are a highly efficient and innovative type of random tower packing widely used in mass transfer processes. Designed to overcome the limitations of traditional packing materials, Plastic Tri-packs feature a hollow spherical structure made from a unique network of ribs, struts, and drip rods. This advanced geometry increases gas-liquid contact while minimizing pressure drop, channel blockage, and media compression interlock.

Structure and Materials

Plastic Tri-packs are made from high-performance injection-molded thermoplastics such as:

  • PP (Polypropylene)

  • PE (Polyethylene)

  • PVC (Polyvinyl Chloride)

  • PVDF (Polyvinylidene Fluoride)

  • CPVC, RPP, and others

They are typically manufactured in various sizes: 1″, 1-1/4″, 3″, and 3-1/2″, making them suitable for different applications and packing densities.
