Klea® 407A
Klea® 407A (R-407A) energy-efficient, lower-GWP solution for commercial refrigeration
Overview
Klea® 407A is a non-ozone-depleting HFC refrigerant specifically formulated for low and medium-temperature commercial refrigeration applications. With significantly lower Global Warming Potential (GWP) than R-404A and R-507, it provides an energy-efficient solution for both new installations and retrofit projects.
Klea® 407A is a proven alternative to R-22 and supports compliance with long-term GWP limits under EU F-Gas Regulations—making it a future-ready choice for industrial and commercial refrigeration needs.
Applications
- Supermarket refrigeration
- Commercial freezers and coolers
- Food processing and cold storage facilities
- Retrofit of existing R-22, R-507, or R-404A systems
- New system designs using lower-GWP refrigerants
Composition (by weight)
- R-32: 20%
- R-125: 40%
- R-134a: 40%
Key benefits
- Lower GWP alternative to R-404A and R-507
- Compliant with post-2030 EU F-Gas regulations
- Non-flammable (ASHRAE A1 classification)
- Non-ozone depleting (ODP = 0)
- Energy-efficient performance in low- and medium-temperature systems
- Versatile – suitable for both retrofits and new equipment
