The advantages of our solution
One System fits all
With our construction kit principle with a single concept you can implement control from any kind of gas engines, to the generator and the whole auxiliary systems, up to central SCADA systems.
Compact layout
By the use of our compact AVAT Technology Modules, the space requirement on the mounting plate is reduced by around 50% compared with conventional layouts with the same scope of functions.
Comprehensive diagnostics & maintenance tool
Our service software E²SERVICE is the perfect tool to keep track of all challenges during commissioning, maintenance, troubleshooting or daily operation. With our pre-configured AVAT VPN-ROUTERN and AVAT CONNECT, we establish the direct connection from anywhere to the plant securely and quickly.
Comprehensive scope-of-supply
The AVAT Applications are delivered with all circuit diagrams, installation instructions, descriptions of functional characteristics and parameters, and lists of limit values. EPLAN libraries and complete circuit diagrams are available for all the components applied.
Complete control system
for CHP engines and modules
E²CON-CHP
The flexible system for engine,
generator and all auxiliary units
The further development of gas engines and new cogeneration plant operating concepts demand a flexible engine controller. One that can keep the engine operating safely at the limit of its mechanical performance while at the same time integrating it seamlessly into the cogeneration plant or into a whole network of plants.
Based on our flexiblehardware and software components, the E²CON-CHP creates a control system for the entire CHP modules including the gas engine. For typical applications we already have tried-and-tested configurations - from circuit drawings to system visualization.
With our modular principle, you implement the control for engine, generator and auxiliary units up to central SCADA systems with just one concept. Ultimately, you decide what we deliver: The standard application or a solution ready adapted to your requirements, on which our or your developers can continue to work.

Marine Dual-Fuel & LNG
engine control system
E²CON-M
To meet strict emission limits, shipping industry is turning to gaseous fuels. For the best control of engines in marine propulsion and onboard power generation we support our clients with a full line of vertically integrated control and automation technology solutions including hardware, software and, importantly, expert consulting.
Optimized output and reliability under fluctuating or uncertain gas quality is the essence of gas engine control. It can only happen if the control system is precisely adapted to the engine and application. With E²CON-M you will quickly get the controller you need for marine gas or dual fuel engines. A modular system of proven elements, E²CON-M is highly adaptable. In close cooperation with the client, we can rapidly develop a customized control system for every marine medium-speed engine. The result: maximum performance, efficiency and reliability even under high load and rough conditions.
Advantages AVAT E²CON-M
- A control system for both the engine and the auxiliaries
- Rapid engine run-up to operating speed
- Compact system layout
- Powerful built-in diagnostic tools
- Approved control hardware components
- Flexibly expandable and adaptable at all times

Safety concept
Based on our unique system integration platform for gas and dual fuel engines, E²CON-M is completely flexible, scalable and open to any kind of extension. Functions, modules and subsystems form one unit with a powerful user interface.
E²CON-M is integrated into the ships automation and consists of three units. The control panel with an engine control and alarms module combined with an engine safety system, the auxiliary panel and a technology component to control combustion characteristics. The control architecture is based on an industrial controller. All modules and devices operate according to the principle "smart sensor" and "smart actuator". They deliver pre-processed information and are controlled and configured by the PLC. All control and monitoring functions access the same data and thus all data is usable in the total system and is displayed on the user interface.
The reinforced cabinet of the control panel and the combustion control unit are vibration-damped mounted on the engine. Wiring of sensors and actuators is directly connected to terminal blocks inside the control panel. As third unit the auxiliary panel is placed away from the engine to simplify wiring of auxiliary inputs and outputs. Redundant Ethernet and CAN connections ensure high operational safety.

Marine Type Approvals
Our company's quality management and development processes are subject to external audits on a regular basis. Thus the E²CON-M components are type-approved by major marine classification societies.
With our engine know-how and experience based on years of working and developing together with major engine builders, we are able to fully support our clients in the process of engine type approval and accompany their project from the drawing board to its sea trials.
