Klea® 32
Klea® 32 (R-32) high-efficiency, low-GWP refrigerant for modern cooling solutions
Overview
Klea® 32 is a high-performance refrigerant gaining global adoption as a next-generation solution for air conditioning and refrigeration. As a pure compound, it offers consistent performance, simple maintenance, and the flexibility to be used on its own or as part of advanced, low-GWP blends.
Applications
Klea® 32 is widely used in:
- Residential and commercial air conditioning systems (new equipment)
- Refrigerant blends as a key component in alternatives to R-22 and R-502, including Klea® 407C and Klea® 410A
Key benefits
- Low global warming potential (GWP)
- Zero ozone depletion potential (ODP)
- High energy efficiency in air conditioning systems
- Pure, single-component refrigerant – no composition shift during charging
- Non-toxic, ASHRAE A2L classification (mildly flammable)
- Easy handling – can be charged in either liquid or vapor phase
- Ideal for use in HFO blendsto further reduce GWP and improve system performance
