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.

Gas domes serve to collect and discharge the produced gases as well as support for various additional digester installations such as mixers, foam traps, inspection windows, pressure safety valves and measurement components. ennox gas domes are configured according to the customer's individual requirements. Special designs for the integration of a mixer are also available. We can also allow for unusual digester forms or space saving combinations of components. Our engineers are happy to support you in developing the optimal solution.

"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."

It s always better to check yourself.... The easiest method to check the fermentation process in a digester is with a glance through our inspection window! Quality glass materials and manufacture, many years of experience and an extensive range of accessories guarantee the meeting of the strict inspection requirements in biogas technology. ennox inspection windows can be installed directly into the digester roof, in a steel or concrete wall or integrated together with other components in the gas dome or manhole cover. Accessories such as spraying units, screen wipers and lights are also part of our program. We can complete your installation with the most up-to-date color zoom camera systems with data storage, data processing and relay via internet.

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.

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...

Bio or sewage gas is saturated with water vapour. Condensation can occur within the pipework systems of digester systems as a result of fluctuating temperatures. The ennox condensate pot allows for the collection and controlled discharge of any condensation water accumulations. The gas flows through the condensate pot where it is channeled within the pot through a separation chamber. The reduction in gas flow velocity and the influence of temperature fluctuations cause the water vapour in the gas to condense and collect at the bottom of the pot. The collected condensate can be discharged from the point of collection either with a siphon or an automatic discharger.

The gas removed from biogas digestion or fermentation units can be heavily contaminated with foam particles, various particulate matter and water vapour. A pre-filtration of the gas (often adequate enough) can be achieved with the use of an ennox gravel filter. The gas flows through the ennox gravel filter layer where large particulate matter and water vapour is left behind. The water collects at the bottom of the filter where it can be drained with a siphon assembly. Following heavy contamination of the gravel filter the spraying unit can be used for rinsing, avoiding the need for opening the digester unit. As an option a gravel removal opening can be installed.

Gas from bio or sewage processing systems are often contaminated with water vapour or very sparsely distributed small particulate matter, which, when used for example in CHP units can cause operating problems or even damage. For the fine cleaning of the gases before utilization an ennox ceramic fine filter is used. In the ennox ceramic fine filter the fine particles contained in the gas are captured by a special fire-clay filter (Pantel). Condensate collects in the form of a moisture layer on the surface of the material and drips into the collector below. An automatic discharge system with level indication can be installed in the base of the digester upon request.

Biogas, sewage gas and landfill gas contains not only water vapour but also a whole host of additional impurities such as hydrogen sulphide, NH3 and siloxane, which, when processed in the utilization system can not only lead to a reduction in efficiency, but also result in damage to the system. The dehumidification of the gas before processing is a basic preliminary requirement in order to permit an efficient usage of the biogas and an investment in the sustainability of the utilization system. With the ennox gas chill dryer the gas to be processed is passed through a heat exchanger where the cooled gas can expel any moisture which drips and is collected as condensate. According to the technical requirements of the installation a post-warming or an economical and ecological energy recovery system can be implemented into the system.
