I hate to be a Debbie Downer on a Sunday morning but I just want to say I really hate cleaning my EHERMS and this is why. First off I have a 20Gal HLT, 15Gal MT and kettle. HLT has a 50’ SS coil and this is my problem cleaning. I have a consistent problem with a thin algae like growth which shows its face upon recirculation to get to strike temp. My process is much like “kals” , The Electric brewery with assuming the sparge will rinse most of the coil out so no worries but that’s not the case. It seems clean but low and behold it’s not come next batch, Algae is back and lots of it. I have started using Sheppard brothers shear 2000 (4oz Gal at 160F) caustic and their acid (4oz Gal at 120F) to clean with a circulation of 30min or so. This is a PITA and I use a lot of the solutions because I need at least 4Gal to cover my element to heat/recirculate. Then I have to rinse everything thoroughly. Then I have to safely dispose of a lot of liquid. Anyway sorry to vent but this is the down side of having such a system and it is what it is. My 3 gal cooler batch sparge set up is waaaaay simpler. Wish there was an easier way. Peace out and I do feel better yours truly Debbie downer☺
