According to whether there is a need for heat preservation in factory, workshop ventilators can be divided into open roof ventilators and heat preservation ventilators. Compared with the former, heat preservation and closed electric smoke ventilator have significant advantages in heat preservation and heat insulation and can control the ventilation volume. It is widely used in areas where the winter is relatively cold.

1. Production process

The level of manufacturing technology of smoke ventilator manufacturers will directly affect the quality of insulated and closed electric roof ventilators. Mcwell has focused on roof ventilators for 17 years, using high-quality profiles and introducing advanced and sophisticated production equipment to produce ventilators and guarantee the excellent product quality.

2. Waterproof method

The steel structure smoke vent rooflight produced by Mcwell adopts full-structure waterproof patented technology. The lap joint of the longitudinal flashing plate and the horizontal flashing plate of the ventilator and the joint of the rainproof plate are buckled to prevent the use of silica gel. The chemical substances that are easy to crack are bonded to the gap, thereby solving the water leakage problem of the natural ventilator from the source. 

3. Insulation performance

The electric smoke vent skylights is equipped with an electric opening and closing valve plate, which can be linked with fire protection. At the same time, the opening and closing of the valve plate can be adjusted according to the internal and external conditions of the plant to control the ventilation and smoke exhaust. In severe cold or snowy weather, closing the valve plate can realize the heat preservation function of the plant and ensure that the temperature in the plant is not affected by the outside world. .
