RUBAG’s automatic gas switching system is an intelligent gas module. It ensures an uninterrupted gas supply for the neutralization of alkaline construction site wastewater without the need for manual intervention. It connects two CO₂ gas cylinders to the neutralization system and automatically switches to the second cylinder as soon as the first one is empty. At the same time, an alarm is triggered so that the empty gas cylinder can be replaced in a timely manner. This ensures that the neutralization system remains reliably supplied with CO₂ even during continuous operation.
The integrated gas heater prevents the valves from freezing at low temperatures or during high CO₂ consumption. The electronic pressure monitoring system allows the gas pressure in both cylinders to be checked at any time—either directly on the unit or online in real time. This simplifies monitoring of the gas supply and reduces the need for on-site checks.

What You Need to Know About RUBAG Gas Switching
Why is an automatic gas switchover useful?
An automatic gas switchover ensures that your neutralization system is supplied with CO₂ at all times. If one gas cylinder is empty, the system automatically switches to the second cylinder—without any interruption in operation.
For which applications is the gas switchover suitable?
The RUBAG gas switchover system was developed for medium to large construction sites where large volumes of water need to be neutralized. It is particularly well-suited for 24/7 operations where a reliable CO₂ supply is essential.
What happens when a gas cylinder is empty?
As soon as one gas cylinder is empty, the second gas cylinder automatically takes over the supply. At the same time, an alarm is triggered so that the empty cylinder can be replaced in a timely manner.
How do I monitor the gas pressure?
The current gas pressure can be read directly on the unit. It is also displayed in real time on the RUBAG website. This allows you to monitor the operating status at all times.
Why does the gas switchover system have a built-in gas heater?
At low temperatures or with high CO₂ consumption, the gas can cool down significantly and valves can freeze. The built-in gas heater automatically prevents this and ensures a constant and reliable gas supply.
How is the gas switching unit connected?
The gas switching unit has two high-pressure inputs for the gas cylinders and one low-pressure output to the neutralization system. This allows it to be easily and safely integrated into existing systems.
What sets the RUBAG gas switchover system apart?
It was developed by RUBAG specifically for professional use on construction sites and is manufactured in Switzerland. The combination of automatic switching, alarms, real-time pressure monitoring, and an integrated gas heater ensures maximum operational safety and an uninterrupted CO₂ supply.
