OLAS is designed to automatically activate Mycro99%K Supreme Blend® and Keeper™ at the desired concentration and proportionally inject activated solution into a variable volume water stream. The biggest advantage to the OLAS is that it is smaller and portable to any part of the plant. The current ppm usage available is 0-100 ppm, but as changes are made, the dosage may go up. All that is needed is a water line.
