Gas dome GAD

"Under certain conditions foam can accumulate in the digester as a result of the fermentation process. If allowed to enter into the pipework, the foam can result in blockage, damage or impair the functionality of safety devices. The gas dome integrated ennox foam trap utilizes a light curtain detection system, which reliably recognizes any build-up of foam and prevents the ingress of such foam into the pipework. With the compact assembly directly on the gas dome, the detection and counter-measures are immediate, therefore requiring no installation of a return pipe system for the accumulated foam back into the digester. As an option, the foam trap can be provided with a fully automatic controller as well as with mechanical over/under pressure safety valves."

Manholes serve to allow unrestricted and safe access to digesters as also an entry point for materials and other components. They are installed either in the cover or the lateral wall according to the application. ennox delivers modern manhole units for either lateral or top assembly in a variety of sizes and designs to suite your individual needs. As well as the traditional design with a screwed fastening construction, we also offer a hinged version, inside opening with quick lock. ennox manholes are manufactured almost entirely of 1.4571 stainless steel and can, upon request, be fitted with sensor openings or other additional fixtures for measurement components.

It is not our goal to simply sell our product to the customer. It is our goal to define the correct solution for our customer's individual application requirements and to offer support throughout the entire specification process with our technical competence, to give the customer all the information required in order to decide, with good conscience, for ennox. Our engineers have accumulated many years international experience and are true professionals in biogas technology. We are happy to offer our engineering expertise during design and specification right through to installation and after-sales support. Further to the implementation of the project we are also at your side! During the last decades the servicing of machines, systems and components has come more into focus. The quality of our customer service associated with the purchase of an ennox system is just as important for our customers as the performance or the price. We offer service or maintenance agreements for...

Floating covers or sludge accumulations forming on the substrate surface in the digester can be combated with a pivoting stainless steel spraying unit PSD. Normally the spraying unit is welded into the gas dome or manhole cover, can be rotated 360 and can pivot within the space available. The water connection can be achieved with a STORZ or GEKA type coupling, alternatively with a standard threaded connection.
