Industrial plants have relatively high requirements for roof natural ventilator and fire-fighting smoke exhaust technology. Therefore, it is necessary for smoke vent manufacturers to perfectly combine the fire-fighting and smoke exhaust technology of natural vent. Through long-term observation and research, Mcwell find that a building has a natural ventilator on one side and a smoke exhaust skylight on the other side. This will increase construction costs and make architectural design complicated. We should know that the daily ventilation of the building can achieve long-term energy saving of the building, while fire-fighting and smoke exhaust are still important and play a key role in special moments.

At present, the technology of smoke vent skylights in other countries develope rapidly. After continuous research and innovation, some manufacturers have produced smoke vents that combine ventilation and fire-fighting smoke exhaust technology. In China, this technology appears to be relatively scarce, but with Mcwell's efforts, the design team already solve this problem.

Mcwell invented a full-structure waterproof technology and parallel air duct type natural roof ventilation. Mcwell obtained more than 50 national patents. Mcwell's natural ventilation system uses the principle of air movement to maintain indoor air circulation, and also have a fire-fighting linkage function. Daylighting natural ventilator is mainly daylighting, supplemented by ventilation. It is also equipped with an electric sensor device, which can be controlled by rain, smoke, wind, and temperature as

needed to realize the fire-fighting linkage function.
