Ventilation ducts
Ventilation ducting tubes can be used in for example mines, tunnels and underground operations. The ventilation ducting tubes are exposed to a harsh environment and need to last for a long time. The HF-welded ventilation ducts are both water- and air-tight.
PVC coating makes the ventilation duct air and water-tight, protects the tube from UV radiation, and is chemical and fire resistant. It is very important that there is no leakage in the joints, and that the seams are strong and durable.
The machine we recommend for manufacturing awnings and sun protection is:
The TDW
The TDW is a large travelling HF welding machine with customized table length and it has 785 mm of free space behind the electrode.
