“I started using a Horner kit when I started my own business because Cscape was free. Before that, I tended to use A-B (shock). I’d first seen a Horner OCS250 when I got sent to Russia to troubleshoot a small Canadian built incinerator around 2004. That was when I found out I could download Cscape and access the coding. The first job I did as an independent was when I used the OCS300 and then a QX651. I ended up using Horner as my first choice because you get familiar with the programming and quirks of the kit very easily. I have ZXs on clinical waste incinerators in the United Kingdom. I have them seven years 24/7 and I have had no failures. I use Smartrail I-O XL4s with SmartMod on agricultural straw boilers in leaky unheated sheds. There have been no failures. The XL7’s are running flue gas treatment plants and woodchip boilers. They have also had no failures. My customers love them. The XL7 is more capable than Micrologix and will compete on scan speed etc. with the Compactlogix. The longest running ZXs are controlling the medical waste incinerators at a big hospital in Cambridge, England. Subsequently I changed the old flue gas filter cleaning controllers (custom reverse pulse boards) for a pair of interconnected XL7s to give more flexible cleaning control on the same plant. Next year I hope to design a waste pyrolyser for a company in New Mexico whom I have persuaded to abandon the A-B on their current United Kingdom built unit in favour of Horner. I usually deal with Don Hurley and the guys in Cork, Ireland. Thanks for being a great source and vendor."
