APPLICATION

Underground Pipe Network

Urban underground pipe gallery is a municipal public facility that implements unified planning, design, construction and maintenance, and is built in the city underground for laying municipal public pipelines.During the construction of the urban underground comprehensive pipe gallery, the workers are actually working in a closed environment or a closed space.

CO2 Detector

Most people spend about 90% of their time indoors. The air we breathe indoors and our health are affected by many factors, including outdoor air quality, the movements of people indoors, and the design, construction, operation and maintenance of buildings.

Pollution Source Detection

The septic tank is a device for processing feces and filtering. The principle is that the solidified material is decomposed at the bottom of the pool, and the hydrated objects in the upper layer enter the pipeline and flow away, preventing the pipeline from clogging and providing solidified objects (feces and other garbage)with enough time to hydrolyze.
