Gas Management System EWR 2 / EWR 2 Net
Up to 60 % Gas Savings!
More economical, more precise and perfectly suitable for the requirements of Industry 4.0!
The EWR 2 systems use a patented function principle with an extremely fast solenoid valve to regulate the gas flow in real-time and in synchronization with the welding current. External factors such as changes in ambient temperatures, changing gas inlet, or counterpressures from the connected cable assembly can be safely compensated. In this way, the EWR 2 guarantees the savings potential and controls the gas flow more precisely than traditional gas control systems.
Advantages that speak for themselves:
- Reduction of gas consumption, therefore reduction in operating costs
- Environmentally friendly; CO2 emission reduced
- Calibrated gas regulation unit
- Active, closed gas control loop by permanent measurement of the gas flow
- Easy handling and monitoring
- Recalibration at the job site possible
- Data recording possible
- ABICOR BINZEL Service Software for standard Windows computers incl. ROI calculator for the amortization period
Applications:
- Can be used in both automated and manual welding processes
- Easy installation on new and already existing equipment
- Suitable for all types of gases
- Gas inlet pressure 1 ‒ 6 bar
- Flow range of 2 – 30 l/min
The Devices at a Glance
EWR 2:
The base for efficient gas management!
1. Button ON/OFF
2. Jack connector
3. Display
4. Gas input
5. Status LED
6. Cross button for device settings
7. Gas output
8. Shunt connection
9. Power supply
All EWR 2 devices have a closed gas control loop at disposal, reducing the deviations between set and actual of gas volume current to a minimum. They are all equipped with an integrated LED display that allow easy overview of the current status and the system parameters. Settings can be done directly with the cross button. Furthermore, the system is equipped with a stereo jack that can be used to connect to a computer with installed ABICOR BINZEL service software.
EWR 2 Net:
Easy networking for industry 4.0!
1. Ethernet interface
2. CAN open interface
EWR 2 Net has two additional interfaces and can be flexibly interconnected.
CAN open interface: The system can be connected by an additional gateway with any fieldbus systems and exchange data in real time.
Ethernet interface: Enables the EWR Net to be integrated into local networks in order to be able to access the appliance through these networks with the ABICOR BINZEL service software.
