Explaining the Advantages of Spiral Duct Machines in the Ventilation Industry for You!

Most of our products are widely used in the construction industry, such as shipbuilding, ventilation, purification, bridge dust removal, airports, and tunnels. After years of research, our company has introduced advanced technology from Switzerland and developed a spiral duct machine that has reached the advanced level in China. Since its launch in the market, it has shown excellent performance and low operating costs. Its application in ventilation and air conditioning systems continues to expand. The duct diameter ranges from 85-1400 mm, with a processing sheet thickness of 0.4-1.2 mm.

System of spiral duct machine

Dust removal system: The spiral duct machine can be used for collection and transportation in dust removal devices;

Fume emission system: Hotels, restaurants, and kitchens produce a large amount of fumes that need to be discharged. The spiral duct is suitable, durable, economical, and practical;

Air conditioning system: The spiral duct can be laminated with insulation material, making it aesthetically pleasing;

Bulk material transportation: Pneumatic conveying system; some finer and looser material particles can be transported through spiral conduits with low cost and good results;

Ventilation system: Supplying fresh air and exhaust, harmful gases are discharged outdoors, while outdoor fresh air is supplied indoors. In general, the ventilation system requires air delivery pipes with low resistance in order to save the manufacturing and operating costs of spiral ducts. Galvanized iron pipes are commonly used, while stainless steel pipes are used in corrosive and particularly humid areas.

Characteristics of the spiral duct machine:

Rigidity

With the same length, fewer flange connections improve the overall performance compared to rectangular ducts, significantly improving the ventilation quality of the system. With the same plate thickness and diameter, the spiral duct has higher strength.

Under the same cross-section, the tension structure of circular ducts is more reasonable than rectangular ducts, greatly improving the rigidity of the duct and significantly reducing vibration and noise.

The appearance of the duct is circular, with an aesthetically pleasing shape.

Speed

High efficiency, suitable for large projects with short construction periods.

No procedures are required at the construction site, reducing on-site personnel and management procedures.

Mechanized production, fast.

Compared with rectangular ducts, the spiral duct machine has a higher standardization of matching special-shaped fittings, making lifting easier and significantly reducing the probability of errors.

A small-diameter spiral duct has a single lifting point and can be quickly lifted. With fewer flange connections, the amount of work required for lifting and connection is reduced by about 50%.

Economy

The lifting efficiency is twice that of rectangular ducts during construction.

Under the same conditions, the low-speed air supply and exhaust can be changed to high-speed air supply and exhaust. The system design can reduce the total amount of ducting, saving both money and space.

Under the same conditions, the whole auxiliary material has a simple structure and a smaller quantity, reducing the installation cost of auxiliary materials by 30%.

According to specifications, under the same duct diameter, the sheet thickness will be reduced by 10%-15%.
