Subject to alteration without previous notice - Code PR019EN - Date: Feb 2014 - Version 01 Transcending the future Let s write together a new chapter in the refrigeration history. THE world s first OIL-FREE COMPRESSOR for home appliances www.embraco.com
New possibilities never tho ught before in refrigeration After many researches, the innovative oil-free concept is now a reality and made possible the development of an all new and revolutionary compressor: Embraco Wisemotion. Oil-Free SMALLER SIZE HIGH EFFICIENCY MINIMUM TEMPERATURE variation LOWER FREQUENCY VARIATION
timeline wisemotion fullmotion In 2000s Embraco innovates again and ON-0ff In the 90s Embraco starts to develop a new compressor concept based on the market demand for more efficiency and less noise. A new electric motor and an electronic device starts to think in a completely new and innovative compressor. A compressor not based on rotation anymore, but on linear movement. More than Since 1974 Embraco has produced made the variable capacity compressor possible. that, a compressor without oil. conventional compressors, from the first model PW to new models like EM and EG. The conventional compressor concept is widely used in the market, based on a circular motion. An electric motor makes the axis rotates in a fixed and single speed. The rotation moves the compressor piston so it displaces the refrigerant gas. This displacement takes off heat from the refrigerator cabinet. Due to the moving parts required to generate The rotary movement is still moving the piston and requiring oil for lubrication. This development generated more than 30 patents and enabled the launching of Embraco Fullmotion in 1998. Today Fullmotion is a wider platform with VEM, VEG, VES and VNEK models, for household and commercial applications. 1998 Different from the conventional and Fullmotion compressors, the new motor drives the piston directly. With a simpler mechanism and innovative ideas, friction was reduced and lubrication oil is not necessary anymore. After 74 patent deposits, Embraco presents its all new Wisemotion, the world s first oil-free refrigeration compressor for home appliances. 2014 refrigeration capacity, it is necessary to have lubrication oil to reduce the friction. 1974 the new cooling history starts now
oil free eco-friendly No oil disposal welcome to a world without oil Innovative ways to design the appliance: Potential to assemble the compressor at different positions and to design new modular cabinets (no oil circulation).
smaller size eco-friendly Less raw material fits anywhere More internal Cabinet Space: Due to its smaller height, Wisemotion has a potential to free up to 20 liters for internal space vs. VEG and 5 liters vs. VES. 203 mm 135 mm 106 mm FULLMOTION VEG FULLMOTION VES WISEMOTION
high efficiency eco-friendly Low energy consumption high efficiency and low consumption ENERGY SAVING: Wisemotion reaches efficiency levels to comply with the most strict regulations. It was born as a top efficiency compressor and has a huge potential to evolve considering the technology maturity. COP LEVELS Similar COP to VEGD levels (R134a) Similar COP to VESC/D levels (R600a) on-off single speed fullmotion variable speed 1974 1998 2014 wisemotion variable DISPLACEMENT
minimum temperature variation health and wellness with less variation FRESHNESS AND food preservation: Wisemotion is able to run in a wider range of capacity modulation to generate cold. Therefore, it delivers less temperature variation, improving freshness and food preservation. on-off FULLMOTION WISEMOTION
lower frequency variation less noise more enjoyment Lower NOISE: Because it s not based on frequency variation, Wisemotion maintains a steady running pace and keeps noise levels low mainly at start up condition and at higher capacities. It can be up to 10dB quieter than VEG at maximum capacity. Start Up Door Opening FULLMOTION WISEMOTION Noise variation during appliance door opening.
