Advanced nute Cool Flame Anyone use??

Anyone here use the cool flame water cooled CO2 burner?? I searched but found nothing. I also need to figure how a PPM controller would work with the cool flame. I already have a controler (green air DH-3) for humidity and temp that will kill the CO2 during venting if temp or humidity get out of range. If I end up with the cool flame I will run a gas line to it so I'm not worried about wasting CO2 during venting so the CO2 controller only needs to handle PPM...
