Biogas
Biogas containers made of HF-welded PVC have the advantage of being water- and gas tight, sustainable and strong. Forsstrom has several HF-welding machines and equipment for producing storage and domes suitable for biogas. HF-welding is the cutting edge technology to use when manufacturing PVC products for biogas storage and since the HF-welded seams are longlasting it is also an environmentally good option.
The machines we recommend for manufacturing biogas containers are:
