The Swing Compressor motor and pump used to power the Engel Portable Fridge-Freezer was developed about 40 years ago. Having only one moving part, it is the only compressor of its type in the world. The Swing compressor is internationally patented and considered the most reliable compressor in the world today. It is the reason the Engel name is world renown for reliability in 12-Volt refrigeration with over 3 million units sold worldwide.
Engel Fridge Freezers are Light weight, offering low power consumption. Their durability and consistent reliability have made Engel the world's premier brand for mobile refrigeration. They are used in Trucks, RVs, airplanes, cars, small and large boats, remote cabins, and anywhere else that has a 12-Volt or 24 volt power source, including solar panels and wind generators. Engel is also used by professional Emergency Response teams to keep life saving drugs cool or IV fluids warm, as well as field biologists and researchers for quick freezing field samples. The Engel can also be powered from standard 120 volt household current.
Engel refrigerator freezers are trusted for their great reliability, superb performance, tough construction, and longevity. Many Engel owners testify to stories of car rollovers and collisions, units dropping off trucks and still performing. Thousands of units, some built in the 1960s are still operating today keeping food and drinks cold or frozen throughout Australia.
This Engel is the best Portable Fridge Freezer in world and is used by many government departments, small and large couriers and trucking companies, health organizations, and food and beverage companies all over the world.
The Swing Compressor
The Swing Compressor is an electro-dynamic reciprocating device that connects directly to the piston of the compressor. It is a true reciprocating compressor with only one moving part. The piston is connected to an electro dynamic device which is powered by the use of magnetic fields. There is no need for bearings, cranks or con-rods, with this technology. Less moving parts literally means less chance of failure. Because the Swing compressor has only one moving part there is a very low friction loss. i.e. This is a highly efficient compressor.
The compressor has no high start up current draw because when it starts up it can simply move down just a fraction then return. Then it slowly increases the distance the piston travels each stroke until it reaches a full stroke. The Sawafuji Swing Motor does not need to perform a full stroke on start up unlike many rotary type compressors that must perform a complete cycle, thereby needing much more current to start.
The Sawafuji Swing Motor is located inside the compressor casing with pins locating in rubber bushes then suspended in between shock absorbent springs. It operates at 30 degrees angles and on rough corrugated dirt roads without losing efficiency. See Diagrams to the right.
