Posted Sun Dec 4, 2005, 11:18pm Subject: Re: how to get drier steam from expobar pulser..
Some water out of the steam wand at the start is normal.. that is why you bleed it off. This is steam that has condensed inside the supply tube /wand since you last used it. As for drier steam.. most of the variables are set at the time that the boiler is designed. To the end user, you might have some success by increasing the boiler head space i.e. lower the normal boiler water level. I haven't owned a pulser, but there is probably an autofill sensor adjustment at the boiler, one of the first things I adjusted when I acquired my Cimbali. Also make sure that you are purging the wettest steam.. don't just get rid of the condensed water, but bleed it for another 5 - 10 seconds. Then wait a short time for the boiler to recover & do another bleed. Now you should have dry steam & be that much closer to microfoam.
