Solutions -ZHEJIANG DONGJIE COOLINGTOWER CO., LTD.

One-stop service Engineered Cooling Solutions for Every
Industrial Environment Different industries operate under different thermal loads, environmental conditions and reliability expectations.
Dongjie develops tailored cooling solutions backed by digital design tools, advanced materials and verified thermal performance—ensuring stable operation in even the most demanding environments.

Our Approach to Industrial
Cooling Solutions

Dongjie's industry solution system is based on three core principles:
- Conduct precise thermal and structural simulations using CTIToolkit, PKPM, SAP2000 and experimental data;
- Optimize materials and tower structures based on composite material technology and modular design;
- Perform verifiable performance verification through test platforms compliant with CTI standards and on-site inspections.
This methodology enables us to meet the industry demands for high operational efficiency, strict temperature control and low downtime requirements.

Why Dongjie Solutions Work The core strength of Dongjie lies not only in its products, but also in its engineering verification capabilities behind the products.
