International. During AHR Expo 2023, Embraco presented the results of a case study with an ice machine that achieved energy savings of 34% after changing its compressor for its own model, the EMX.
In that study, a model using R404A refrigerant was replaced by the Embraco EMX compressor, which runs on R290 natural refrigerant. The change also provided a 35% increase in ice production.
Michel Moreira, Sales Director for the North America region at Nidec Global Appliance and Head of Embraco's portfolio, said: "For us, the study shows that the migration to natural refrigerants is the coming trend for the ice machine market, as it is a win-win situation: reduced energy costs and increased productivity, combined with lower environmental impact, because R290 has a near-zero global warming potential (GWP), while R404A's GWP is 3,922."
He also assured that this is a 'future-proof' solution, since it is suitable for current legislation and which in the future will establish the limits in the GWP (Global Warming Potential) of refrigeration equipment.
Compressor Details
One of the most important aspects of the Embraco EMX compressor is that it has an equivalent displacement range of 4 cc to 9.5 cc and a cooling capacity of up to 2,985 BTU/h (ARI MBP).
For ice machines, as well as other gastronomic applications that demand a higher cooling capacity, Embraco will highlight the NEX and NTX compressors. The former reaches up to 21 cc and 6,480 BTU/h cooling capacity, while the NTX reaches up to 33 cc and 10,200 BTU/h (ARI MBP).
In addition to ice machines, it is suitable for a variety of applications, such as undercounter refrigerators, reach-in refrigerators, freezers, professional kitchen refrigerators, bottle coolers and beer displays, thanks to the high engine starting torque (also suitable for thermostatic expansion valve) and high efficiency.

The AHR Expo was also the place for visitors to get to know VNEX: Embraco's new variable speed compressor. This device is large enough for commercial reach-in freezers up to 5 doors and large commercial refrigerators without doors, and offers the highest cooling capacity and energy efficiency in its class.
Finally, the brand also highlighted that variable speed compressors come with an integrated set of electronic components that control the operating speed of the compressor according to the demand of the refrigeration equipment, and the energy savings can reach up to 40% compared to a fixed speed compressor, depending on the application.
"Variable speed is the best way to balance energy and food preservation regulations and requirements in the foodservice segment, especially in low-temperature applications," Moreira said.
