The engineering behind a drop-in refrigerant.
Every Eco Kold blend is built to match a specific legacy refrigerant on three axes: pressure curve, temperature glide, and oil compatibility, so the install becomes a recharge instead of an equipment swap. This is where the technical detail lives: comparison data, specifications, operating envelopes, and what "low-GWP" actually means under the hood.
Four technical references.
For engineers, contractors, and procurement teams evaluating Eco Kold.

Side-by-side performance: every Eco Kold blend against the synthetic refrigerant it replaces. GWP, charge weight, operating pressure, exit temperature, energy reduction.

Full technical specs for each blend: composition, Safety class, oil compatibility, charge math, UN number, and applicable code (IEC 60335-2-89).

Field-use pressure-temperature charts for each blend. Print these for the technician: they're the same format as a manifold-side reference card.
View P/T charts →What "low-GWP" actually means
The phase-downs, the regulatory schedule (AIM Act, Kigali Amendment), the math, and the practical difference between Eco Kold's GWP of <1 and an HFO blend's GWP of ~300.
