Customer Comment

Our skilled experts are on hand to create a solution together with you that is perfectly tailored to your specific requirements and processes.

Some years ago, we purchased coal-fired SZL series steam boilers and YLW series thermal oil heaters from ZOZEN. They had been running stably up to now and provided the reliable and sufficient heat source for our production line. This time, we did not hesitate to choose ZOZEN again.

The cooperation with ZOZEN was very pleasant. It not only completed the boiler coal-to-gas project for our Haida Group, but also provided a stable steam heat source, which effectively reduced the emission of atmospheric pollutants and played an important role in improving the surrounding environment.
