Scanner Systems
Rowan Technologies' patented scanner systems have on-line monitoring and mapping capabilities, tailored for both low and high temperature industrial plant including power generation boilers, and include:
- Corrosion, erosion and crack monitoring.
- Heat flux and fireside tube wall temperatures.
- Tube wall slagging, fouling and cleaning
- Identifying damaging temperature-related tube wall conditions e.g. boiler flame impingement.
The systems use arrays of sensors, directly attached to external plant surfaces, and are capable of mapping large areas, or be used for monitoring smaller, localised areas. They are non-intrusive, as the item of plant itself becomes the 'sensor', avoiding the requirement for probe entry ports or tube removal, especially important where pressure vessels are concerned.
The first scanner system was installed in 1999. Our longest-serving system was installed in 2001 and is now set to continue monitoring until at least 2013, a testament to the system's long-term reliability.
Systems are available for dedicated thermal monitoring or for corrosion, erosion, crack monitoring (with in-built thermal monitoring capability).
As well as 'fixed' systems for continuous monitoring, portable systems are also available for periodic measurements.
For our 'fixed' scanner technology, we can supply small evaluation systems that can be extended at a later date to monitor much larger areas.

Corrosion Probe Systems
Our range of probe systems for industrial and boiler plant provide information on corrosion/erosion rates at specific locations. Our VTER probe technology ultimately led to the development of our scanner systems, above.
Corrosion probes are available with temperature controlled corrosion elements. Air cooling is used to accurately control the element temperatures.
