The future of ventilation starts now
CO₂mpass as a guide to a sustainable future
In a time when sustainability is not just an option but a necessity, Menerga is guiding the way. With CO₂mpass, we’ve redefined ventilation and air conditioning technology – combining efficiency, safety and environmental responsibility in one solution.
Rethinking ventilation. Redefining efficiency
CO₂ technology
Innovation in HVAC means breaking away from outdated technologies. Menerga’s CO2mpass represents a bold step forward, using the natural refrigerant R-744 (CO2).

The next step in swimming pool ventilation: CO₂mpass
Video
CO₂mpass sets new benchmarks in swimming pool air handling – with natural CO₂ refrigerant, 100% PFAS-free, and maximally efficient.
The natural advantage of R-744
Why choose CO₂ as a refrigerant?
R-744 (CO2) is a naturally occurring substance found in the atmosphere, soil and groundwater. As a refrigerant, it offers multiple environmental and technical benefits:
GWP = 1
Our refrigerant sets the benchmark with a minimal Global Warming Potential (GWP) of only 1
PFAS-free by design
Completely free from per- and polyfluorinated substances – for a cleaner, safer future
F-Gas Regulation? Not an issue.
Our technology is not affected by the latest EU F-Gas Regulation (EU No. 2024/573)
Safe by nature
Non-toxic and non-flammable – ensuring peace of mind in every application
Simple and safe handling
Safety requirements easy to fulfil make installation and maintenance hassle-free
No leakage checks required
Reduced service effort thanks to the exemption from mandatory leakage monitoring
