Gas cabinets and panels for heat treatment plants


Since 1996, AVION Europe’s field of activity has expanded enormously and, in addition to spare parts and services, increasingly includes complex tasks such as the design of gas mixing batteries, modernization of control systems (e.g. S 5 to S 7), control cabinet construction and the creation of complete SCADA systems according to individual customer requirements.

In the following, we explain our delivery options in these areas in bullet form. Prerequisite for all respective systems: Intensive consultation by our specialists with many years of experience in the heat treatment industry.

The SCADA system

The construction of individual SCADA (Super-visory Control and Data Acquisition) systems is the new flagship of AVION Europe’s service portfolio. Our customers use SCADA systems to control their plants across sites, and to collect and record data about their operations.

AVION Europe’s SCADA systems, which are individually tailored to our customers, usually include a combination of software and hardware elements, such as programmable logic controllers (PLCs) and remote control terminals (RTUs). Data collection begins with the production equipment at the plant level, which communicates with the manufacturing equipment via sensors.

The data collected in this way is then transmitted to the next level, such as a control station, where operators can monitor the PLC and RTU controls using human-machine interfaces (HMI). AVION Europe SCADA systems allow operators and higher-level interfaces (QA, production management…) to control processes either locally or remotely, as well as to interact directly or centrally with all components such as motors, pumps and sensors.

In addition, AVION Europa SCADA systems enable our customers to monitor, document and archive their processes using real-time data.

AUTOGEN – control system for endogas generators

The AUTOGEN is a precision gas mixing and control system for endogas generators.

The system features a patented control that uses electronic flow measurement and precise ratio control to consistently deliver the ideal gas mixture for high-quality endogas production.

The AUTOGEN significantly lowers the operating costs, since up to a gas/air ratio of 1:5, excess gas no longer needs to be flared off. The type of control ensures that the generator only produces the amount of protective gas that is required for production. Annoying manual fine adjustments are no longer necessary.

Features and benefits:

  • no flaring (1:5): Reduction of operating costs
  • Significant reduction in CO² emissions
  • minimizes maintenance
  • Endogas is available immediately after heating up to operating temperature:
    • no “running in” of the generator necessary
    • Minimizes setup and startup time
  • constant control of the gas/air ratio
  • Constant regulation of the dew point: less soot formation
  • clear display on a color touchscreen

Included in the system

  • colored touch screen
  • Integrated dew point measurement and control
  • integrated temperature measurement and control
  • permanent ratio control gas/air mixture
  • integrated, digital chart recorder (data storage for 5 years and more)
  • electronic air mass meter
  • digital quantity display air / natural gas or propane / endogas
  • safety route
  • air inlet filter
  • Frequency converter for stepless control of the blower motor


  • power meter
    110/220 V at 50/60 Hz

  • blower power
    230/460 V 3 phases

  • flow rate
    2.8 – 170 m³/h
    2.8 – 390 m³/h

  • partial load range
    5:1 (or greater)

Conversion from endogas to methanol/nitrogen
Conversion natural gas/propane

The continuing price increases for natural gas are leading our customers to consider moving away from endogas as an inert gas and instead back to methanol/nitrogen as an inert gas atmosphere.Methanol and nitrogen have also increased in price, but not to the same extent as natural gas.

Also, at present, the supply chain risk for methanol/nitrogen is much lower than for natural gas.Our control systems rely on the components of SSI Supersystems, which deals exclusively with mixing and measurement systems for different gases. Conversion from natural gas to propane or LPG is also possible at any time with SSI components.

Our specialists with decades of experience in the heat treatment industry will support you competently and actively in your decision and implementation.
