Congratulations, you have just acquired the 1000th rotary kiln scanner from HGH!

For a couple of decades, HGH’s kiln shell thermal scanners have been very successful worldwide, with sales figures in constant progress. In 2012, our manufacturing team was proud to deliver 100 kilnscans on schedule. It is now an evidence that the 1000th system will be sold this year, which rewards our continuous commitment to customer satisfaction. Now HGH’s thermal monitoring system is a central element in most control rooms of cement plants, in more than 50 countries around the world.

Kilnscan 23 is the latest version in the family of HGH’s thermal scanners. It shares the robustness of previous versions, with scanners still in operation 20 years after their commissioning. It also adds some unique features, such as the widest scan angle on the market, up to 140°, which enables the scanning of the entire shell, with only one sensor, even if the free space is limited around the kiln.

Kilnscan 23 will alert any hotspot at the earliest, thanks to high spatial and high thermal resolutions. It is the only temperature scanner in the world to provide thermal warp monitoring, a must for predictive maintenance, as it displays in real time the evolution of the kiln axis distortion. Kilnscan optimizes kiln performances and clinker production quality, as well as, reduces refractory maintenance costs and energy wastes.

Scanning the kiln to reduce operating costs – This article gives an overview of the minimum features and performance that thermal scanner should exhibit, to reduce risk of unexpected breakdowns, and thus operating costs. Compared with losses induced by unscheduled shutdowns, the return on the investment in a thermal scanner is really short. And no concession on scanner performance should apply, to reduce level of risks.
