PDF Version

Refplus approves the following modern refrigerants to their medium and low temperature refrigeration evaporators, condensers and condensing units.
The following refrigerants can be used:

  • Honeywell Solstice N40 (R448A) GWP 1273 •
  • Dupont Opteon XP40 (R449A) GWP 1397 They are replacements for R-22, R404A, R507 and R407A/C/F

They offer a similar capacity of R404A with a reduced energy requirement and with a glide of +- 7°R (4°K).
Use suffix 6 (same as R407A/F) for your condensing units. Use the same operational requirement.
