Cooling Tower Dot-wave Fill

Cooling Tower Dot-wave Fill

Jinyang cooling tower dot-wave fill is a PVC film packing with a point-like raised-dot surface pattern. The dots promote turbulence and water distribution across the sheet, giving good cooling performance while resisting channeling in the cooling tower.

How It Works

PVC sheets are thermoformed with a regular pattern of small raised dots. Water spreads over the bumpy surface as a thin, turbulent film while air flows through the open channels. The dots break up the film and redistribute water, preventing dry patches and improving heat transfer.

Key Features

• Dot-pattern surface - promotes turbulence and even water distribution.

• High efficiency - large wetted area with good mixing.

• Low pressure drop - open channels allow efficient air flow.

• UV-resistant PVC - stable in outdoor tower service.

• Chemical resistant - withstands treated water and common chemicals.

• Easy installation - modular packs on support grids.

Technical Options

Sheet thickness 0.3-0.5 mm, pack sizes to match tower fill height. White or black PVC; flame-retardant grade available.

Typical Applications

Counter-flow and cross-flow cooling towers in HVAC, power, chemical, and industrial process cooling.
