brief introduction

Adopting a pre cooling device with independent flanges to achieve pre cooling followed by pressure reduction, in order to improve the service life of the primary and secondary doors., The instrument panel is equipped with a centralized arrangement of online instruments, manual sampling basins, and alarm devices for various waterways, reflecting the characteristics of separating water and electricity, and separating high-temperature components from instruments. This provides good conditions for the operation and on-site maintenance of instruments. The operation of multiple large, medium, and small thermal power plants has shown that the reliability and efficiency of the devices are among the top in this field, The optimization level of its entire system has received high praise from industry experts and full recognition from users.


Structural composition

The complete set of soda and water sampling devices consists of ① high-temperature rack (hot work rack); ② Instrument rack (dry panel); ③ All chemical instruments; ④ Water sample constant temperature device; ⑤ Closed cooling water device; ⑥ Composed of microcomputer data acquisition and control system. Combine according to actual needs. The most basic water vapor sampling device is composed of the first four combinations.

Two stage traditional cooler, integral pre cooling series, split pre cooling series
