Drone inspection of flue gas channels
Avoid scaffolding or sending crews into flue gas channels during inspection. We do the inspection work with drones.












Innovative flue gas channel inspection with drones
What is the condition of your flues? Most people don’t actually know. Unfortunately, it’s very common not to check the inside of a facility’s flue gas ducts due to the difficult conditions and the cost of scaffolding. Therefore, it often ends in guesswork. But not for much longer. We take the guesswork out of the equation and fly through ducts down to 500 diameter with our drones.

Always the right solution
The benefits of drone inspection of flue gas channels
There are many advantages to having your flue gas channels checked by drone. One of the biggest is that drones allow you to get in and inspect areas that you would normally put off inspecting or never actually look at.
By using drone inspection of the channels, we make sure to detect wear and tear or damage before it potentially ends up in a shutdown of the entire facility. This is of great value as unforeseen downtime can be prevented with drones.
When we do a drone inspection, we look for corrosion and tears, among other things. If your ducts are made of fiberglass, we also look for blisters or peeling – and we actually look at your compensators from the inside, which provides a wealth of information about the condition of the compensators.
Do you also want a drone inspection of your chimney? We can do that too.

More about our drone for flying in flue gas channels
We use an Elios 3 drone, which is designed specifically for inspections in hard-to-reach areas and confined spaces. The drone is equipped with a safety grid and has a size of 48 cm wide and 38 cm high, which means we can fly in most ducts. Want to inspect ducts that are smaller than this? No problem, we have other equipment to solve such tasks.
When we fly through a flue, our drone also creates a 3D model with a LiDAR laser scanner, which we then link to the video we record. In this way, we can easily map where various damages are located in the facility and report them to you via our interactive reporting system.

The value of flue inspection
There is great value in having a flue gas duct inspection. It makes it easier to budget and make investment plans for repairs to the system. In addition, it also provides information on how the system runs during operation. The flue gas ducts can help reveal useful information that is very valuable for both operations and maintenance personnel.

Frequently asked questions
Why is it important to inspect flues?
Many facilities rarely have their flue channels checked because scaffolding is cumbersome and expensive. With drone inspection, we can easily identify damage and wear and tear, which can prevent unforeseen breakdowns and expensive repairs.
What damage can a drone inspection reveal?
We look for corrosion, tears, blisters and peeling in fiberglass ducts as well as the condition of the compensators. This provides a detailed assessment of the condition of the ducts.
What type of drone is used for the inspection?
We use an Elios 3 drone, which is specially designed to fly in confined spaces and hard-to-reach areas. It has a security grille, a 4K camera, LED lighting and a 3D LiDAR scanner to map damage.
How small flue gas channels can be inspected with a drone?
Our Elios 3 drone can fly in ducts as small as 500 mm diameter. If the ducts are smaller, we have specialized equipment to get the job done.
What report do we get after the inspection?
We provide an interactive report with a 3D model of the canal combined with video footage. This makes it easy to locate and analyze damage so that maintenance can be planned efficiently.
Can you also inspect the chimney with a drone?
Yes, we can also perform a drone inspection of your chimney to give you a complete assessment of the entire system.
