Five blends. One drop-in retrofit for nearly every system in the field.
Each Eco Kold blend is engineered to match the pressure curve, temperature glide, and oil compatibility of a specific legacy refrigerant. So installation is a recharge, not a retrofit: same compressor, same evaporator, same lineset. GWP of <1, zero ODP, 55–65% less charge weight depending on the blend.
