The tricking filler is in the cooling tower water, the main components of the gas exchange, is to improve the cooling efficiency of the cooling tower, and to ensure economic and safe operation of the key. With the development of the plastics industry, plastic watering filler: "S"-type ladder wave, dual-slope the gambrel-wave, thermal performance, ventilation resistance, durability, drawing easy, widely used in different types of large, medium, small cooling tower. As a result of the bonding assembly, packing is very good overall stiffness.
