double membrane biogas dome 1. easy installation, beautiful 2. Unique controlling system 3. lifespan for 15 year

Detailed information:

Our double membrane biogas domes is located at the top of fermentation cylinder, it also can be used as a cover for fermentation cylinder. This saves much money. Meanwhile, we have taken many advanced technologies to make our storage system to function well and have a long lifespan. 

For long years of be specific in our biogas tank manufacture,  We have many unique design that other company may not have.

1. Ventilation between the inner membrane and outer membrane.

If there is few biogas in the air between, so we must ventilate. As we konw biogas are explosive gases, so it would be dangrous to let it be there.

2. Dranage design between the inner membrane and outer membrane.

If there is temperature difference, it will form condensation water.  Specially, in cold area, water will easily freeze, this will totally do harm to the storage system. So we have dranage system between the inner membrane and outer membrane.

3. Special designed inner membrane

We have taken advanced tension structure, which makes the inner membrane try to be as less folded as possible. This will greatly increase the lifespan of biogas tank.
