Glad to be here.
A couple of year ago , at at HVAC show in Anahaim Ca i talk with a company wich manufacture heater exchangers out of cultured rocks instade of cooper fins (something like the catalitic converters in cars or like the pumice stone!)
I have one idea wich include something like that but i can not locate the bussines cards or the material they sent to me. I know that they are out of East Coast but i can not remmember for the life in me.
Any of you out there have any idea how i can find that company ?
