Relying on a thermal performance testing platform that complies with CTI standards, as well as professional tools such as CTI Toolkit, PKPM, SAP2000, and the self-developed thermal calculation software "three-in-one verification", we ensure that the design of each cooling tower is more precise and reliable, and its performance is more stable.
The independently developed composite material (FRP) structure features light weight, high strength, corrosion resistance and long service life, significantly reducing maintenance and operation costs. It represents the development trend of the new generation of industrial cooling towers.

Dongjie is committed to reducing water consumption, optimizing thermal performance and extending product lifespan through advanced materials and intelligent design.
Our FRP structures, high-efficiency fill media and digital thermal modeling help customers achieve lower energy usage and long-term environmental benefits.
