Klea® 134a
Klea® 134a (R-134a) refrigerant
Overview
Proven performance. Global standard.
Klea® 134a is the trusted, industry-standard replacement for R-12 refrigerant in both retrofits and new equipment. With zero ozone depletion potential (ODP) and performance that matches R-12 in medium and high-temperature applications, it offers a reliable and responsible solution across a wide range of systems.
Widely used in automotive air conditioning, Klea® 134a is also a key component in many lower global warming potential (GWP) HFO blends—supporting sustainability goals without compromising performance.
Key benefits
- Non-flammable and classified as an ASHRAE A1 refrigerant (low toxicity, low flammability)
- Zero ODP for regulatory compliance
- Global availability as a widely adopted industry standard
- Flexible system charging – suitable for liquid or vapor recharge
- Balanced capacity and efficiency for optimal system performance
- Broad compatibility with most air conditioning and medium-temperature refrigeration systems
