Lighter frame but same engine with a 1000psi psi pump which means it can have a bigger blower which is direct drive,
it's next to the one i rebuilt in the picture
less lights and fuss and much simper with bigger heat exchanger which was kicking out some heat yesterday. Also not to sure but seams like it uses less water but that might just be in my mind.
And yes you need to link two together otherwise you would never be able to get the skin off a custard obviously a rice pudding is out of my league.
