The glass fiber reinforced plastic circular counterflow cooling tower is corrosion resistant, high in strength, light in weight, small in size, small in area, beautiful and durable, and convenient for transportation, installation and maintenance. Therefore, it is widely used in various sectors of the national economy, and is particularly suitable for cooling water circulation systems such as air conditioning, refrigeration, heating furnaces and condensation processes. The circular counterflow cold glass fiber reinforced plastic cooling tower adopts counterflow gas heat exchange technology, and the filler adopts high-quality modified polyvinyl chloride wave plates to diffuse the water area and rotate the water distribution method to achieve uniform water distribution and enhance the cooling effect.
