Carbon dioxide (CO₂) is a gas we all breathe out, but too much of it in a sealed room can be dangerous. Breathing air with high CO₂ can make people feel tired, dizzy, or worse—causing serious health problems or even death if it gets very bad.
In places like shelters or secure rooms that must stay closed without fresh air coming in, CO₂ builds up quickly because people keep breathing in oxygen and breathing out CO₂. This buildup is even faster in busy, active environments where people move around and work hard.
How Our CO₂ Removal System Protects You
Sigma Power Tech has designed a special system to keep the air inside these sealed spaces safe and breathable. Our system carefully removes the extra CO₂ from the air, so everyone inside can breathe freely and stay healthy—no matter how long they are inside.
This system is truly unique and one of the most advanced available, inspired by technology used in places like submarines and space shuttles. Unlike older, bulky systems that take up a lot of space and need lots of work to maintain, our solution is compact, efficient, and easy to operate.

How the System Works
The system cleans the air through two parts that work one after the other:
- One part removes CO₂ from inside the shelter and sends it safely outside.
- While that’s happening, the other part cleans itself and gets ready to start working again.
It switches between these two parts automatically to keep the air fresh without stopping.
The system comes with a simple control panel with a touch screen that can be used right there or remotely. It can also connect with building controls to keep you updated on the air quality and system status all the time.
Additional Oxygen Support
For shelters where people stay a long time, the system can be linked to add extra oxygen if needed. This ensures the air inside always stays comfortable and safe.
