It is suitable for roof ventilation and fire smoke exhaust in industrial plants with highly corrosive gas and liquid emissions.

The development of modern industrial process, especially in the steel structure factory buildings in the field of industrial construction, the corrosion phenomenon is omnipresent and can be seen everywhere.

Severely corrosive environments can cause destructive corrosion to the factory's basic equipment, structures, exposed surfaces, etc., especially to the walls, roofs, and ventilation towers of steel-structured factories. This not only greatly reduces the overall image of the factory and brings about many leakage problems, but also seriously affects the safety of the factory.

There are many acid rain belts in China. For example, the eastern coastal areas are prone to severe acid rain. The acid rain problem every year causes incalculable losses. Therefore, it is urgent to solve the problem of corrosion in industrial factories. Ampelite uses its unique technical expertise to solve the overall corrosion problem of steel structure factories. Among them, anti-corrosion skylight natural ventilators are an effective solution to the corrosion problem of factory roof skylight natural ventilators in severe corrosive environments.

AMPELITE Anti-corrosion streamlined skylight natural ventilator (Type I)
The anti-corrosion streamlined skylight natural ventilator has strong ventilation capacity and is suitable for industrial plants or civil buildings with large ventilation requirements. This structure has a large roof load and the form of the skylight natural ventilator base needs to be considered.

The anti-corrosion streamlined skylight natural ventilator adopts a post-processing method for the structural frame. The frame is first made according to the conventional method, and then wrapped and covered with the fifth-generation special material of Ampelite AN FF using various proprietary technologies. After processing, the frame has an atmospheric appearance and is resistant to various corrosion. Even in a heavy corrosion environment, it can still be used for more than 15 years.

Note: The fifth generation of Ampelite FF special material package (FF fifth generation for short) is the result of years of research and experimentation by Ampelite. It is mainly based on special resins and reinforced with glass fiber. It uses special processes and a variety of additives and auxiliary materials to solve the adhesion between the material package and steel and the delamination or micro-cracks caused by the different thermal expansion coefficients of steel and the material package under natural temperature differences. The operating temperature is -25°C-65°C.

The enclosure structure is made of FRP anti-corrosion material, and the FRP material is made into various required enclosure structure components through protrusion, thermosetting reinforced composite and winding. The enclosure structure components made of FRP are light, high-strength and highly corrosion-resistant. The actual service life is more than 20 years in normal environment, and can still be used for more than 15 years even in severe corrosion environment.

Connectors are various auxiliary parts that connect purlins, frames and enclosure systems, mainly screws, rivets, clamps, bolts, etc. All the auxiliary materials of the connectors of the anti-corrosion skylight natural ventilator are made of anti-corrosion materials, such as special anti-corrosion screws, special waterproof closed aluminum rivets, hoops made of PVC anti-corrosion material, and bolts made of 304 stainless steel.

AMPELITE Anti-corrosion Slope Valve skylight natural ventilator (Type II)
Anti-corrosion down-slope valve type skylight natural ventilator is suitable for down-slope small throat (800mm, 900mm, 1000mm, 1200mm, 1500mm) steel structure roof, without the need for a skylight base structure, can be directly fixed on the roof purlins, which can meet the factory's anti-corrosion and ventilation requirements at the same time.

AMPELITE Anti-corrosion thin skylight natural ventilator (Type III)
Anti-corrosion thin skylight natural ventilator (Type III) can be applied to the entire roof structure, with modular unit combination design, good rainproof performance, and no limit on the size of the throat. This ventilation structure has good wind pressure resistance and less roof load.

AMPELITE Anti-corrosion thin skylight natural ventilator(Type IV)
Anti-corrosion thin ventilation skylight natural ventilator (Type IV) can be applied to the entire roof structure, with modular unit combination design, good rainproof performance, and no limit on the size of the throat. This ventilation structure has good wind pressure resistance and less roof load.
