Gasholder installed on tank

The top mounted storage tank is installed on concrete or steel tanks. A central mast combined with straps prevents the inner membrane from touching sludge or mixers at low gas levels.

Application: Agricultural and industrial plants
Usual pressure range: 5 – 10 mbar


-Plant specific design
-Easy to maintain
– Installation on concrete tanks / steel tanks
-Belt support construction to prevent contact with sludge or inbuilt components (mixers, etc.)
-Simple and safe system, less components, reliable gas detection system can be installed
– Safe and efficient anchoring system
-Special blower to prevent pressure changes while 24/7 operation
-Measurement with 4-20mA output signal to control plants PLC
-Reliable hydraulic safety valves (overpressure/vacuum)
-European membranes according biogas rulesheets
-Separate air in /air out – system, to prevent colour change
of outer membrane. Also smoothens pressure curve
-Automatically closing claps at the air in / air out system
-Electrical components according to ATEX
