Partial operation data
Project operation effect
During system operation. With the joint efforts of both parties, during the operation guarantee period of Shandong Dadu new materials Co., Ltd., the water quality of the internal circulating water system is stable, the inner wall of the heat exchanger is free of scaling and corrosion, and the cooling tower is free of microbial breeding, which effectively reduces the risk of scaling and pollution blockage of the system and ensures the stable and normal operation of the system.
