The CUPOLA M1 SPRING is primarily used in livestock facilities, in particular for applications such as multiple, interconnected digesters or the replacement of rubber-covered wooden roofs.


As compared to existing systems, the CUPOLA M1 SPRING provides many advantages, including:


Increased weather resistance, including wind resistance, due to the dome being under constant tension, even when not filled, resulting from steel springs connected around the circumference the membrane and anchor.


Better gas tightness and durability due to the superior performance of PVC membrane compared to EPDM rubber and specialized welding techniques.


Low cost of investment driven by an optimized design and reduced energy and maintenance costs due to the absence of the need for an air pressurization system.


Ability to operate at higher operating pressures compared to competitive products thanks to the mechanical strength of the membrane and air pressure control valves.


Accurate level control due to the CUPOLA M1 being equipped with a patented electro-mechanical system accurately records the level of the internal biogas membrane’s apex, so that operators can accurately gauge the volume of biogas stored in the gasholder.
