Underground Ventilation Solution |
Reduced Energy Consumption due to Minimal Leakage |
- Spiral ducts have minimal air leakage
- Spiral ducts up to 12 meter length require less joints and thereby minimize the risk for leakage
|
Quick and Easy Installation |
- Spiral ducts have low weight
- Spiral ducts are faster installed as a result of their longer length availability
- Standard connection solution are used for Spiral Ducts
- Standard fittings are used for Spiral ducts
|
Durable |
- Spiral ducts have superior mechanical strength
- The lock seam on Spiral ducts reinforces the ducts resulting in thinner material requirements
- Spiral ducts can be produced with corrugation, which also allows production with thinner material
- Spiral ducts stand both high positive and negative pressure
- Meet norms for friction, K Factor
|
Huge Savings in Transportation and Logistics |
- Eliminate transport costs
- Eliminate stock and handling costs
- Eliminate costly shaft operation
|
Costs per Duct |
- On-site production enables minimized costs per duct
