Nah, mate.
No expert here, but being doing some (alot) reading and the Engel uses a sawafigi (Japan) and waeco used to use the danfoss, but now it's there own brand which is the danfoss assembled in China.
I think .

Yes correct. The Sawafuji is a piston type compressor and the danfoss in a, rotational type?, compressor. If thats what you call it. Without googling it I think thats the differences between the two. I will say, the ARB fridge is almost dead silent, all I can hear is the fan running, where as the Engel I can clearly hear the compressor.
