Embraco Introduces R600a Miniature Compressors for Residential Refrigeration

0

The smaller of the two new compressors is only 123mm high; both models will enter commercial production before the end of 2021.

Brazilian compressor maker Embraco, a brand of Nidec Global Appliance, has launched two new miniature isobutane (R600a) compressors, the FMS and ES models, for the residential refrigeration segment.

Both models have a very small size, with the variable speed FMS compressor measuring only 123 mm (4.8 inches) in height. The FMS is a third smaller than its predecessor, the EM3, but retains the same maximum cooling capacity of 265W (0.075TR). It is suitable for applications ranging from small beer and wine coolers to larger multi-door refrigerators.

Both compressors have a “remarkable combination of innovation, energy efficiency, environmental sustainability and a unique correlation between cooling capacity and size,” Embraco said in a statement.

They will be in commercial production before the end of 2021 and will be available worldwide. Embraco already has customers who plan to take advantage of the smaller compressors with new cabinet designs, the company said.

“ES and FMS represent a new step in our product portfolio,” said Ricardo Bristotti, vice president of home appliances at Nidec Global Appliance. “The two [compressors] are products at the cutting edge of technology. In particular, FMS brings new design possibilities to residential refrigeration due to its small size.

Up to 40% more efficient

The FMS has been developed to make it up to 40% more energy efficient than traditional fixed speed compressors. An additional advantage of the new variable speed model is that it has a noise level 15-20% lower than that of equivalent stationary compressors, when operating in steady state.

The other model, the ES, is fixed speed and suitable for applications such as water chillers and residential refrigerators. It’s slightly larger than the FMS, at 155mm (6.1 inches), but still smaller than the previous EM3 ​​model, allowing more space inside the cabinets as well. It has a capacity of 166 W (0.047 TR), which is “about 20% higher than the market standard for this size class, with 1.83 W / W of energy efficiency,” according to Embraco.

An added benefit of the ES is the flexible suction port which adapts to the system configuration. The ES is a total solution, said Embraco, stressing that the main objective of the model was to “meet the needs of the market in the Americas.”
