Soooo....
.... to make nitrox with a membrane, all vendors propose a LP scre compressor, drier, membrane and then use the HP compressor to put it into storage cylinders. To have redundancy on your liveaboard, we'd need to of each, including filters ,driers ,etc.
It all adds up.
NOw, do we really need a LP compressor? What about instead of 2 LP , expensive screw compressors with all the asssessories, use a extra HP compressor to fill storage cylinders and via a reducer, produce Nitrox via the membrane. That way, you have practically oil free air meaning longer membrane life, only one type of compressor, great redundancy and you save $$ too.
Screw compresssors use more oil I'm told so they need filters to make the air oil free and , oil that can create problems in the HP compressor.
This setup may not be as efficient but it also means you get a very simply system: 3 HP compressors, great redundancy and very flexible capacity control .
Anything wrong with this picture?
