Product Portfolio

  • The comprehensive process control that is based on our gas analysis systems AwiECO and AwiFLEX ensures smooth operation and last, but not least economic efficiency of your plant on a permanent basis.

    The more accurate and continuous the measurements, the more they prove to be a cost and time-saving factor.


    Small control tasks can be managed by AwiECO and AwiFLEX. For more complex solutions with requirements for automation we have developed AwiCONTROL.

    • With AwiCONTROL you can control your whole plant including all peripheral devices. This customized solution also provides maximum operational safety and makes sure that you can keep your operational expenditures low.

      It goes without saying that we do not raise any licence fees for our software. With the same consistency we continue to develop our products on an open source basis to avoid hidden follow-up costs for our customers.

      Of course, AwiCONTROL - as our other products - can be controlled "on-the-go". Via smartphone or tablet. Everytime.

      modular, expandable, future-oriented

      • AwiCONTROL is manufacturer-independent: Communication with all established PLCs through standardised bus protocols.
      • AwiCONTROL is hardware-independent: Whether industry control panel or conventional PC for remote maintenance, our solution operates in all systems and is fail-safe. Replacing of components and/or transfer to other hardware is possible without any problems.
      • No need of software licence: Not to mention that all necessary programs are open source, the whole plant control is based on an open source Linux-system.
      • AwiCONTROL keeps records: Besides the logging of all user interaction, all sensor value modifications as well as the switching status of digital in-/output are recorded.

                  FuzzyLogic is a method of artificial intelligence used to integrate complex expert knowledge into an automated system in an easy and efficient way. Low concentrations of oxygen in the biogas result in a biological desulphurization process. However, if the oxygen concentration is too high, the whole system can be damaged and the collection rate of biogas is reduced. Therefore the air supply has to be effectively regulated. In fully automated mode the Awite process analysis system measures the concentration in the biogas of

                  • hydrogen sulphide
                  • oxygen

                  and controls the

                  • allowed value of oxygen
                  • amount of air supply needed

                  with the ultimate aim to

                  • keep the concentration of the hydrogen sulphide as low as possible
                  • reduce costs
                  • achieve a high process stability
                  • account for marginal losses of substratum

                For process monitoring it is important to constantly check the main features and states of the plant. Awite offers you the necessary sensor systems for monitoring your whole plant, in ex zones (hazardous area) as well as in non-ex zones. We only use products of well-known manufacturers (mainly products developed by Endress & Hauser):

                • Fill level and point level
                • Pressure
                • Flow
                • Temperature
                • Humidity

                  • You can rely on us. And on our systems.

                    The assembly, commissioning and maintenance of our process analysis systems is carried out by our skilled personnel directly on-site. We monitor the service intervals for you and offer full maintenance service on request. Moreover we keep maintenance costs reasonably low for you by offering planned visits for calibration as well as scheduled appointments.

                    The maintenance service does not only comprise of the calibration with certified gases but also includes a full check of the systems. On-site service is the key to an error-free operation and gives you time to carry out other important tasks.
