Dear Sirs, Really we are interested only in pressurized type heat pipe integrated with tank ( no water inside tubes ) but only, I repeat, only with EN 12976 certificate, not EN 12975. ( EN 12976, the certificate is used for the integrative system not for split ).Do you have this certificate? If yes, please show it to us. Sure you understand, have a nice day. Waiting for your reply Yours sincerely Country:Italy
