All Engel Fridge-Freezers are powered by the unique Sawafuji Swing Motor. Japanese technology at its best, the Sawafuji Swing Motor has only one moving part. Unlike many rotary type compressors, the Motor does not need to perform a full stroke on start up, meaning that it does not have a high start up current draw. The Motor operates at 30 degree angles and on rough corrugated tracks without any loss of efficiency, making it the most effective choice of motor for Engel.
The piston is connected to an electro dynamic device which is powered by the use of magnetic fields. With this technology there is no need for bearings, cranks or con-rods, and less moving parts means less chance of failure. With only one moving part, friction loss is very low, resulting in a highly efficient compressor.
