My experience indicates running a system for 2 hrs does not demonstrate the system is capable of a sustained output. Of particular concern is the plugging of the air wands used for de-aerating the product. I have had several instances where these devises would work for a day then plug or coat over badly and not work at all until they were disassembled and physically cleaned (typically hot water and/or detergent). I am expecting the Chronos system to work better than prior attempts but I don’t think 2 hrs is enough time to understand this.
