GWP value
Why the GWP value is crucial for sustainable air conditioning technology
The Global Warming Potential (GWP) is a measure of how much a greenhouse gas contributes to global warming compared to CO₂ over a set period of time (usually 100 years) For example, methane (CH₄) has a GWP₁₀₀₀ of around 30 – it is therefore 30 times more harmful to the climate than CO₂ over the same period of time. A higher GWP value means a greater climate impact per kilogram – which is why the use of refrigerants with a low GWP is crucial for real climate protection.
Modern refrigerants – climate protection with effect
Why the change makes sense:
- Stricter regulation: EU F-Gas Regulation bans F-gases with a high GWP of over 2,500 in new and refill systems from 2025/2026.
- Cost advantages remain: Low GWP plants produce fewer CO₂ equivalents – save money through lower taxes, certificates and leakage controls .
- Sustainability target: Contribute to reducing climate-damaging emissions by up to 79% by 2030.
Examples of climate-friendly refrigerants:
- R32 (GWP 675), around 69% less harmful to the climate than R410A (GWP 2088)
- R454B (GWP ~466) – 78 % less harmful to the climate compared to R410A
- CO₂ (R744) as a natural refrigerant with GWP 1 – almost climate-neutral
- Ammonia (R717) – GWP & ODP = 0, environmentally friendly
Advantages for industrial halls & heat pumps from LK-Metall
1. hall ventilation with REKU 10 ventilation systems with heat pump
In sophisticated industrial technology, LK-Metall relies on heat pumps that use modern, low GWP refrigerants – such as R32 or R454B. These generate heat for hall heating and ventilation systems in an efficient and climate-friendly manner.
Advantages:
- Significantly lower CO₂ emissions per kWh of heat
- Compliance with the EU F-Gas Regulation
- Savings in energy costs and operational safety
2nd REKU 10 cooling technology
The REKU range works with climate-friendly refrigerants (e.g. R32 or R290). This reduces the GWP value of the entire system enormously – environmentally friendly, efficient and future-proof
3. complete heat pump solutions
LK-Metall also offers complete solutions with heat pumps based on low-GWP refrigerants (e.g. R32 or R290). These systems are ideal for industrial halls, office buildings or production plants, as they provide heating without fossil fuels – with low emissions and eligible for subsidies.
How your company benefits in concrete terms
| Measure | Climate impact | Economic advantage |
| Conversion to low-GWP (R32) | -70 – 80 % CO₂ equivalent per use | Less leakage costs, lower CO₂ tax |
| Use of natural refrigerants (R290) | Climate neutral | Funding options, image boost |
| Heat pumps & REKU systems | Reduction of primary CO₂ emissions through electric operation | Lower heating/cooling costs, legally secure |
Recommendation: Act now – check GWP value, reorganize technology
- Carry out a GWP analysis – which refrigerants does your system use?
- Technology check – is it possible to switch to low/natural refrigerant?
- Advice from LK-Metall – find the right solution together, including advice on subsidies.
- Modernize instead of replace – retrofit with REKU + heat pumps for long-term climate security.
Conclusion
The GWP value indicates the climate impact of refrigerants compared to CO₂ – the lower, the better for the climate. With its REKU10 ventilation systems and modern heat pumps, LK-Metall offers precisely the technologies with which industrial plants can now heat and cool in a legally compliant, efficient and environmentally friendly manner.
