Inspecting ‘live’ tanks

Inspecting 'live' tanks

WHEN a local utility company needed to conduct a routine surveillance check on one of its anaerobic sludge digesters, the specialist company Hayes GFS contacted Ashtead Technology in its search for an intrinsically safe-rated inspection camera.

Following discussions with Ashtead Technology’s engineers a suitably certified push-rod camera was deployed from a customised access point that enabled the Hayes’ staff to produce comprehensive images and videos showing the condition of the digester’s roof and walls.
The application called for an instrument certified for use in potentially explosive environments. In this case a Pearpoint P374 camera system was used in conjunction with a digital video recorder.
