Today, more and more companies are switching from rectangular to
Spiral Ducts round rigid duct work. Why is this? What advantages do spiral systems have over rectangular. The answer is simple.
- Energy efficient
- Cost less to install
- Often requires less space
- Need less hangers
- Operation cost lower
- More noise free
- Installation simplified
- Cleaning less complicated
- Air flow measurement easier
- Light in weight.
The perimeter of round ducting system is less by 20% or more of same cross section of rectangular ducting. Hence, the area of ducting and insulation required is less by the same percentage.
Applications of Spiral Ducts:
- Air conditioning ( including high pressure and velocity air distribution systems )
- Ventilation ( Industrial & Tunnel )
- Warm air heating
- Fume and dust extraction
- Pneumatic conveying
- Exhaust and air intake pipes
- Humidification.
Specifications of Spiral Ducts:
- 0.40mm( 28G ) to 1.6mm ( 16G )
- Thickness of Sprial ducts as per SMACNA ( HVAC Duct Construction Standards )
