DuPont publishes R404A retrofit guide
2014-10-31
DuPont has produced a must-read document for anyone considering converting an R404A or R507 system to its new alternative XP40. With a European service ban on R404/507 systems being introduced in 2020, and with high GWP refrigerants coming under increasing pressure elsewhere, there is expected to be huge interest in lower GWP “drop-in” alternatives.
