Medexon BV recently performed successful and efficient internal drone inspections of 2 chimneys for the company Poujoulat, a European market leader in chimney and exhaust solutions. The chimneys with heights above 60m have been inspected using the Elios 2 caged drone. In the concrete chimney the drone footage was used to document the renovation already done. In the steel chimney we did a native inspection to document changes verses an earlier inspection done by robe climbers. The job was done in less than half a day offering high quality 4k footage and avoiding human entry.
