ZPLXE for single-stage compressors and ZPSLXE for two-stage. Information about Copeland's LXE product line, including brochures and FAQs, is available on their website. Copeland also recorded a free webinar about their LXE line.

As with the air conditioning compressors, the model numbers starting with Y are compatible with flammable refrigerants. Some of Copeland's models are even manufactured for R-290 (propane, which is an A3 refrigerant), which is becoming more popular with the even tighter GWP restrictions in commercial and industrial refrigeration. Currently, several heavy commercial and industrial refrigeration applications have lower GWP limits than the 700 we've seen for residential air conditioners and heat pumps. We're already seeing GWP limits of 150 and 300 in market refrigeration and industrial applications. Some A2Ls fit the bill already (namely R-454A and R-454C), but there is still the question of what future regulations might entail. The European Union and the United Kingdom have already reached the point where R-32 is slated to be phased out as part of the F-Gas Regulation (which aims to phase out HFCs by 2050). We're not there — at least not yet — in the USA, but if we want to stay ahead of the curve, we should pay attention to the replacements. The refrigerants that have been discussed as replacements are "natural" refrigerants R-290 and carbon dioxide (CO2 or R-744). Natural Refrigerants and Specialized Compressors R-290 is extremely efficient and has a low GWP (3). However, it's highly flammable and requires small charge sizes as a result.
