Klea® 125
Klea® 125 (R-125) versatile building block for next-generation refrigerant blends
Overview
Klea® 125 (R-125) is a key component in many widely used blended refrigerants that serve as effective replacements for legacy refrigerants like R-502 and R-22. It is an essential ingredient in popular blends such as:
Klea® 407C
One of the first commercially available blends suitable for both retrofit and original equipment in R-22 systems
Klea® 407A
A lower global warming potential (GWP) alternative to Klea® 404A and Klea® 507
Widely applied in commercial and residential air conditioning and refrigeration, R-125 delivers efficient cooling performance and reliability.
Applications
- Supermarket refrigeration
Klea® 125 is used in supermarket and grocery store refrigeration systems, helping to preserve freshness and safety of food products. - Data center cooling
Data centers depend on R-125-based systems to maintain precise temperature control, ensuring uninterrupted operation of servers and critical IT infrastructure. - Industrial cooling
R-125 plays a vital role in industrial cooling processes, including chemical manufacturing and pharmaceutical production, where exact temperature regulation is critical.
Key benefits
- Highly versatile
Used in almost 20 refrigerant blends, such as R-410A, R-404A, and R-407C, with new blends continually being developed. - Excellent safety profile
ASHRAE A1 rating means R-125 is non-toxic and non-flammable, making it a safe choice for a wide range of applications.
