Elios 3 - The Drone for Inspection in Confined Spaces
At Drone Eksperten, we use the Elios 3 drone from Flyability to perform drone inspections in confined spaces.
Drone Eksperten specializes in confined space inspections using drones. We deliver safer, faster, better, and more cost-effective inspections. To achieve this, top-tier equipment is essential. That’s why we have partnered with the Swiss company Flyability, which develops drones and software specifically for confined space inspections. We use the Elios 3 drone – their latest and most advanced model – designed for safe indoor flight and operation in tight spaces to perform precise and detailed inspections.

The Elios 3 Drone’s Many Features
In an era where confined space inspections demand both precision and safety, the Elios 3 drone is a true game-changer. At Drone Eksperten, we have chosen this advanced drone to ensure our inspections meet the highest standards. Here is an overview of its key features:
1. Protective Cage
The Elios 3 is equipped with a robust protective cage that safeguards both the drone and its surroundings. This cage acts as a barrier during inspection flights, reducing the risk of damage from accidental collisions—an essential feature when operating in tight and potentially hazardous environments.
2. Full LED Illumination
To ensure optimal visibility in all conditions, the Elios 3 is fitted with integrated LED lighting. Whether operating in dark industrial facilities or inaccessible spaces, its powerful illumination provides clear and detailed footage, which is crucial for accurate documentation.
3. 4K Camera
With an advanced 4K camera, the drone captures images and videos in impressive high resolution. This feature is vital for documenting inspections in the finest detail, allowing potential issues to be quickly identified and analyzed with high precision.

5. UT Payload for Thickness Measurement
With the UT Payload, the Elios 3 can perform ultrasonic-based thickness measurements. This feature enables precise evaluation of material thickness, which is critical for detecting potential weaknesses or wear in structures. By identifying these areas early, preventive measures can be taken before the issues develop into serious faults.

6. Gas Sensor
Safety is paramount when inspecting industrial and confined environments. The drone is therefore equipped with an advanced gas sensor that can detect the presence of hazardous gases. This feature ensures that any gas leaks or contaminants are detected in time, protecting both personnel and equipment from potential risks.
7. Thermal Camera
The thermal camera in the Elios 3 allows real-time temperature variation measurements. By identifying areas with abnormal heat anomalies, the drone can detect issues such as overheating or leaks, which may otherwise be invisible to the eye. This is particularly important when inspecting complex systems, where temperature differences can indicate internal faults.
8. Range Extender
Finally, an integrated range extender ensures that the drone can operate over longer distances without losing connection. This is a significant advantage when inspecting large facilities or complex infrastructure, where it’s essential to cover extensive areas without compromising data quality.

The Range Extender for the Elios 3 drone allows for signal extension, enabling longer operational distances without loss of connection.
With these advanced features, the Elios 3 delivers a unique combination of safety, precision, and versatility – perfect for modern confined space inspections. At Drone Eksperten, we are proud to use this technology to provide safer, faster, and more efficient inspections that meet our clients’ high demands for quality and safety.
