Embraco’s mighty Atom
29th April 2025
BRAZIL: Nidec’s new Embraco Atom is claimed to be the most compact variable-speed compressor for residential applications.
Weighing just 2.5kg and measuring less than 110 mm, it is 30% lighter than Embraco’s previously most compact compressor, the FMS.
The company insists that the Atom is designed to be competitive enough to accelerate the migration from fixed-speed to variable-speed technology, being accessible to a wide range of refrigeration applications, from premium models to single-door refrigerators and beverage coolers.
“The Atom was developed as a global platform to support the widespread adoption of variable-speed technology, and our initial key markets include China, Europe, and India,” explained Alberto Casnati, president of Nidec Global Appliance.
The product operates on R600a (isobutane) refrigerant and has a COP of up to 1.90W/W.
A number of innovative solutions are incorporated in the Atom to achieve its small size, low noise and energy efficiency targets. One of these is the use of a polymeric discharge line to replace the traditional metal discharge tube. This is said to be key to the reduction in the compressor’s size, as well as decreasing heat dissipation, vibration, resonance and noise, without compromising performance.
The Atom comes with an ultra-compact inverter, capable of intelligently extracting peak performance from the compressor and actively controlling its vibration levels, making it more silent. Noise levels are reduced by up to 5dB compared to standard market compressors.
