Alfa Laval has a fairly good technical service
set up, up should be able to call them and get all the info you need. What are you going to run that on? Engine oil
? you'll never have to change the oil
ever, just add a bit as needed. I've seed smaller one for large trucks and even smaller one for farm tractors that or powered by the oil its self. Now are you setting this up as a clarifier or a purifier?
