Product Description:

spiral-ducts Spiral ducts are rolled spirally using a GI coil by a special machines, The spiral ducts are easy to manufacture, and are widely used in various industries. Specially in HVAC industries. Spiral ducts are normally made of thinner materials, and light weight in nature and the spiral joining formed over the surface adds more strength to it. Since this ducts are lighter , doesnt require heavy supports and can be easily hanged from roof / wall. Spiral ducts has its own limitations like thicker spiral ducts cannot be made easily and also loses is also bit higher in comparison to other ducts having smoother inner surface.

Since air being a compressible fluid, the ducting should be properly designed for maximum efficiency with minimum losses. If the ducts , bends, branches etc..are not properly designed considering proper bend radius or process parameters like dust loads, moisture content, dust carrying velocities wont serves its purpose. Powder accumulation on bends occurs, more velocity and pressure would have been lost as friction. Improperly designed ducting system will have more friction loses, and increases blower power consumption as well as power bills. Properly designed ducting system consumes less power and gives more cost savings in long term.
