Corrugated paper treatment, high structural strength, long service life. It has excellent osmotic water absorption, which can ensure that the water evenly penetrates the entire wet curtain wall.

The specific three-dimensional spatial structure provides a large evaporation surface area for the heat exchange between water and air. The outer frame is available in aluminum alloy and galvanized sheet.

The cooling process of the YBH pad cooling system is done inside the paper pad. There is a thin film of water on the surface of the corrugated fiber paper, when the outdoor hot and dry air is sucked through the paper pad by the fan, the water on the water film will absorb the heat in the air and then evaporate in the water vapor, so that the cool and moist air after treatment will enter the room. This natural process is like the wind blowing across the water.
