Saving over $1 million: wind turbine inspections with the Elios 3
Safety The Elios 3 allows for safe access to the interior of wind turbine blades without requiring personnel to enter dangerous or confined spaces. This significantly reduces the risk of accidents and injuries during inspections. Speed With the Elios 3, inspections are twice as fast. One drone can inspect up to four turbines in a single day, while traditional methods usually only allow for one or two per day. This efficiency saves time and resources. Costs Identifying faults early with the Elios 3 can save over $1 million per wind turbine blade by preventing costly replacements and reducing maintenance expenses. Access Wind turbines can be over 170 feet tall, making manual access difficult and dangerous. The Elios 3 provides easy access to these towering structures, minimizing human exposure and fall risks. Wind energy has been a source of power for centuries, starting with ancient windmills used for agriculture and later evolving into modern wind turbines that now contribute significantly to global electricity production. In 2022, wind energy accounted for 7.33% of the world’s total energy supply. As the demand for clean and renewable energy continues to grow, so does the need for efficient and safe inspection methods for wind turbines. However, wind turbines are complex machines. Their blades can be over 170 feet long, and some of the largest turbines have rotor diameters exceeding 800 feet. These massive structures require careful inspection and maintenance to ensure they operate safely and efficiently. Traditional inspection methods often involve climbing into tight spaces or using scaffolding, which is both time-consuming and risky. That's where the Elios 3 comes in. This advanced drone is designed specifically for inspecting hard-to-reach areas like the interiors of wind turbine blades. It offers a safer, faster, and more cost-effective solution for wind farm operators and maintenance teams. Joseph Valenzuela, the Operations Manager at Pathfinder Optics, is one of the professionals who has embraced this new technology. With years of experience as a drone pilot and non-destructive testing technician, Joseph recognized the need for safer and more efficient inspection tools. He founded Pathfinder Optics with the goal of using robotics and drones to improve safety and reduce costs in various industries, including wind energy. Today, Pathfinder Optics uses a range of robotic systems and drones to conduct inspections across multiple sectors. Their focus on wind turbine inspections has led them to adopt the Elios 3, a drone known for its durability, maneuverability, and advanced LiDAR capabilities. Joseph credits the Elios 3 with helping his team deliver high-quality results faster than ever before. Joseph initially used a standard rotary drone for inspections, but he quickly realized that it wasn’t suitable for the tight, confined spaces inside turbine blades. That’s when he turned to the Elios 3. Its protective cage allows for confident navigation through narrow passages, while the LiDAR and visual data provide detailed insights into the condition of the blades. In a recent project, Joseph inspected four wind turbines in a single day. Each inspection involved climbing to the hub of the turbine, entering the blade through an access hatch, and flying the drone along the length of the blade. The process was completed in under three hours, a feat that would have been nearly impossible with traditional methods. The portability of the Elios 3 made it easier to transport to remote sites, and in some cases, it could even be winched up while Joseph climbed the tower. Once inside, the drone provided clear visuals and precise measurements, helping Joseph identify potential issues quickly and accurately. Using the Elios 3, Joseph can conduct thorough inspections that help prevent costly damage. For example, if a blade is damaged due to lightning strikes or grease buildup, the consequences can be severe. Replacing a single blade can cost over $1 million, but early detection through drone inspections can help avoid such expensive repairs. LiDAR scans also play a crucial role in identifying structural issues that might not be visible to the naked eye. These scans provide detailed 3D models of the turbine blades, allowing inspectors to spot cracks, deformations, or other signs of wear and tear. This level of detail ensures that maintenance can be planned proactively rather than reactively. Drone inspections also offer significant safety benefits. Instead of having workers climb into dangerous spaces, the Elios 3 handles the most hazardous parts of the job. This not only protects employees but also reduces liability for the companies operating the wind farms. Additionally, drones are invaluable in emergency situations. If a turbine catches fire or there's a sudden malfunction, the Elios 3 can quickly assess the situation without putting anyone at risk. This rapid response capability can make a big difference in preventing further damage and ensuring the safety of nearby personnel. For Joseph, the Elios 3 is more than just a tool—it’s a game-changer. “I’m not a fan of heights, and this drone lets me work quickly and safely,†he says. “It gives me peace of mind knowing I don’t have to crawl into the blades or take unnecessary risks.†Since adopting the Elios 3, Joseph has completed numerous projects along the West Coast of the U.S., helping wind farm operators improve safety and reduce costs. His work demonstrates how modern drone technology is transforming the renewable energy sector, making it more efficient, sustainable, and safe for everyone involved.

A heat exchanger is a device used to transfer heat, usually to transfer heat from one fluid to another without them mixing. A heat exchanger usually consists of a number of parallel pipes in which one fluid flows through the pipe and another fluid flows through the outside of the pipe. In this way, heat can be transferred from one fluid to another for heating or cooling purposes. Heat exchangers are widely used in many industries, such as chemical, pharmaceutical, food processing, air conditioning and heating systems, etc.
Heat exchanger usually consists of the following components:
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects.
