Better heating performance 6% for BTW and 12% in ATW application when compared with both R410A and R290 Consider to the refrigerant properties, the changing of R410A to R32 can keep compressors stoke volume Meanwhile 57% stoke volume increasing of R290 must be implemented to keep the same capacity level, Consequently R32 is theO At 100F, evaporating pressure in an R290 system is approx 46 psig o At 100F, evaporating pressure in an R134A system is 266 psig (See pressure chart in upper right column) EPA has exempted R290 from Section 608, Venting Prohibition;The specifications of R 600a and R 290 according to DIN 60 1998 are as follows Specification Unit Refrigerant content 1 ≥ 995 % by mass Organic impurities 2 ≤ 05 % by mass 1,3Butadiene 3 ≤ 5 ppm by mass Normal Hexane ≤ 50 ppm by mass

Description EcoPure R290 and R600a are refrigerant grade products that meet AHRI 700 Standard purity requirements The EcoPure refrigerants are colorless and nonodorized, so extreme care is required when handling these refrigerantsEcoPure R290 and R600a refrigerants are approved by the EPA's SNAP program for the US market, effective April 15 for food servicePressure R290 14 Capacity R290 A difference between R290 and R134a is in the pressure level, which is closer to R22 and R404A, eg at 25 °C evaporation the pressure is roughly 190 % of R134a, 81 % of R404A, 350 % of R600a or almost exactly that of R22 In connection with this the normal boiling point, is close to R22 alsoProduct Information Used in verylowtemperature refrigeration systems, typically the low stage of a multistage system R508B has properties similar to R503 and can be used to replace either R13 or R503 in an existing system The discharge temperature does not increase significantly compared to R23 POE lubricants should be used, and it may
