With the continuous development of HVAC industry, product layout is quietly changing. Low-carbon energy-saving has become the basic demands of HVAC products. HVAC companies continue to use advanced technology to improve the  energy efficiency of air conditioning products, the development of  alternative energy sources and renewable energy, the development of new  refrigerants.

Spiral  duct on the market by the material is generally divided into three  categories: galvanized spiral duct, stainless steel spiral duct and  composite spiral duct. In  order to achieve the goal of energy saving and environmental  protection, the enterprises are carrying out relevant activities around  the theme of energy saving and environmental protection. In the new  product development, product design, manufacturing process, technical  transformation of production line and so on, we will increase the  investment. At the same time, in the production also focus on energy  conservation, the enterprises have developed a sound evaluation system,  in the capacity of the premise of increasing efforts to reduce energy  consumption, production links also minimize pollutant emissions.

       The  installation of the helical duct significantly reduces the connection  between the pipe and the pipe, minimizing the leakage of the pipe joint,  the typical length of the spiral duct is 3 to 6 m, and the typical  rectangular duct length is only 1 ~  1.5m; and the connection of two spiral ducts only one pipe fittings,  and the traditional spiral duct connection is often required a  completely independent double flange system.
