The M-series is a new MAYEKAWA compressor for the next generation with maximum flow of 1.278m3/h displacement. As a result of reflecting all the technologies that MAYEKAWA accumulated for the past 85 years, we achieved world-class excellent COP (13 to 15% higher than conventional MAYEKAWA compressor models) and compressor maintenance has become more simplified with less work. Also, the M-series can work at a maximum speed of 1,500rpm with our latest technology. Furthermore this compressor is not only applicable for refrigeration, but also for heat pumps because it can work with an operating pressure of 2.6MPaG. It is notable that this compressor is most efficient at a temperature around -10?. Therefore it is suitable to use for ice production, skating rink, and cold storage warehouse.
