It is replacement for R22 and R502 in low temperature refrigeration system.
R290 or propane gas currently stands out for its wide range of applications in both the commercial and industrial fields. This gas has practically unbeatable properties in any of its applications, due to its GWP (Global Warming Potential) = 3 and an ODP (Ozone Depletion Potential) = 0. However, on the other hand, being a class A3 refrigerant, it is a non-toxic, but extremely flammable refrigerant. R290 has similar thermodynamic properties to R22, although certain characteristics such as capacity and working pressures are lower. Even so, it has excellent therm-physical properties and its thermal efficiency is good for most conditions, including high ambient temperatures, where the discharge temperature is low. Advantages â?¢ Natural, environmentally friendly and efficient refrigerant. R290 or propane gas is a natural refrigerant and has a low cost due to its abundance. In addition, it has high energy efficiency, thanks to its thermodynamic properties and high performance, which will lead to cost reduction. Climate adaptability. R290 gas has been shown to be better adapted to hot climates than HFCs. Performance. Their smaller displacement compressors further increase efficiency in industrial equipment, while also delivering high performance in commercial applications. Wide range of application. R290 refrigerant is fully suitable for both commercial and industrial equipment and systems. Good compatibility with other components. Reduced charge of R290 refrigerant. Obtaining a higher efficiency and performance than other refrigerants with only 40% charge. Long-term solution free of fluorinated refrigerants. This natural refrigerant is a safe bet for the long term, as it has no future environmental restrictions and is free of refrigerant taxation. Applications: â?¢ Commercial Refrigeration Systems. â?¢ Industrial Refrigeration Systems. Chiller Systems. Chill Cabinetry. Vending. Cold Storage. AC Systems. Heating Pumps.
