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.

Apzem Plate Column Scrubber is the simplest ofwet scrubberand works on and are custom designed to capture dust particles, VOCs, chemical fumes, and other water / chemically soluble fumes and Vapors generated in industrial process. Spray tower scrubber is of low efficiency in comparison to other wet scrubbers at a lower pressure drop. Apzem had a strong team of consultants and engineers having deep knowledge in design and commissioning of wet scrubber across various industries for different applications. contact us to assist you in selecting efficient and economical scrubber to your specific process and pollution control needs.

Air/Gas Pollutants Removed: Application:

Industrial ducting made of mild steel had very wide application because its low cost in comparison to other ducts and easy to manufacture. M.S ducts easily gets rusted and will not be able to withstand corrosive environment, in some condition having mild corrosive environment, MS ducts lined with FRP or with special coatings (Epoxy coatings etc.) with serves efficiently. We could also use FRP ducts, SS ducts, GI ducts, Spiral ducts, Aluminium ducts, Flexible ducts along with MS ducts together forming complete ducting system based on applications.

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 etc.it wont serves its purpose. Powder accumulation on bends occurs, more velocity and pressure would have been lost as friction. Improperly designedducting systemwill 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.

Application Industries:

Apzem had a strong team of engineers having deep knowledge in various industrial processes, duct design, international ducting standards (SMACNA, AMCA etc.) . We are happy to assist you in selecting, designing ducting for your process needs.

In an Industrial Environment, proper ventilation should be provided to maintain the efficiency, health and safety of workers. The indoor environment of any industries may have sources generating heat, fumes, VOCs , dusts etc.that are harmful to workers and it should be controlled and kept within allowable limits set by OSHA (Occupational Safety & Health Administration) and Industrial Hygienists standards to minimize absenteeism of workers, Increase productivity, avoid explosion and fire at workplace.
Based on the indoor air contaminants concentration, allowable TLV-STEL ( Threshold limit value - Short Term Exposure Limit) Values, Explosion limits, any of below ventilation methods can be chosen to effectively maintain industrial environment.
