Product Description


Biogas Digestion Enamel Steel Tank Mounting with Membrane Gas Holder







Biogas digestion tank we are providing is enamel coated bolted steel tank mounted with double layer membrane holder roof . The outer layer of membrane roof works as the protection for the inner membrane . The outer membrane is more strong and coated with UV resistance coating . By working of air blower, the outer membrane forms a hemispheric balloon thus keep the roof in shape . The inner layer of membrane roof is more gas-tight . The biogas generated by the underneath digester will be temporarily stored at the space formed by the digester and the inner membrane . So this is so-called inter-grated biogas digester - biogas digestion and biogas storage are realized by this same unit .

The membranes are highly tear resistant polyester fabrics with a special PVC surface treatment and acrylate varnish. The fabric is also resistant to the impact of the different biogas ingredients and the white colour of its external membrane has a highly reflective effect. The construction and dimensions of the double membrane biogas storage tank comply with all relevant standards.

· Biogas storage system fabric is highly flame-poof according to DIN 4102-B1

· Higher specification fabric is available on request

· The special surface treatment formula guarantees high resistance against permeability & UV

· All biogas storage tanks are resistant to wind and heavy snow and guarantee safe operation

· The temperature resistance ranges from –30°C to +60°C

Enamel Coated Bolted Steel Tank Panels Manufacturing Process


1. CAD Design: all the tanks are designed as per client’s request by CAD - work stations

2. Laser Cutting: Center Enamel adopts most advanced 3500W laser cutting machine to meet the best cutting performance

3. Shot Blasting: Comparing chemical processing, our advanced physical Shot Blasting ensure quality of each sheet

4. Rolling: according the different request and dimension

5. Pre - treatment: Each sheet will be pre - treated before enameling

6. Enameling: using automatic production line to enamel all panels

7. Firing: The temperature of firing oven is 850 degrees Celsius

8. Test: Center Enamel tests every sheet with 1500V holidays test and other tests

9. Packing: All the glass fused to steel sheets are packed in wooden boxes
