WebChoice 421A. No unit oil change required, unlike other R-22 alternatives. With no measurable pressure difference to R-22, retrofitting with R-421A is simple and familiar. WebR22 has a very similar boiling point to R290 (-41.4°F to 44°F; that’s only a 2.6°F difference). At 100°F, however, the pressure of R22 is 195.9 psig and the pressure of R290 has a pressure of 174.3 psig (check the R290 PT chart below). This is a 20+ psig difference and you will easily tell if you have an R290 or R22 freon. handpiece cleaning machine https://pillowtopmarketing.com
