THE GREEN NATURAL REFRIGERANT

Hydrocarbons are environmentally benign refrigerants. Their global warming potentials (GWP) are considerable lower than fluorinated refrigerants. R290 has a GWP of 3, which is relatively insignificant when you look at R22, R134a and R404a, which have global warming potentials of 1.810, 1.430 and 3.922 respectively.
Hydrocarbons also have lower discharge temperatures, improving the system reliability and performance.

Upgrade Your R22 Units with Climetal Microchannel Condensers & R290

If you’re exploring new options for your R22 units, Climetal’s microchannel condensers combined with R290 offer an excellent alternative—delivering efficiency, reliability, and sustainability.

Why R290? A Near-Perfect Match for R22

R290 (propane) is a highly efficient, low-GWP refrigerant with thermodynamic properties that closely match R22:
✅ Boiling Points: R290 (42.1°C) and R22 (40.8°C) are almost identical.
✅ Evaporating Temperatures: R290 (-42.1°C) and R22 (-40.8°C) align perfectly, meaning you can use the same evaporator design.
✅ Lower Discharge Temperature: R290 runs cooler than R22, enhancing compressor reliability and lifespan.
✅ Higher Pressure Ratios: Improves overall performance and extends the capacity range by 5%.
