Currently, human inspectors enter explosive atmospheres subjected to strict restrictions -including emptying and venting. Fuel released in this operation creates an environmental impact with a significant carbon footprint in addition to the associated cost. However, the main cost of these inspections is associated to the stop time. San Jorge Tecnológicas has recently, developed a new technology that will provide a unique solution to this problem: A pneumatic ATEX-compatible flying drone. The flying drone is especially thought for the inspection of hazardous facilities such as the inner part of a deposit, oil, and gas holding vessels or other confined containers with volatile and potentially explosive atmospheres. The drone is specifically designed for IECEX Class 1 Division 1 or ATEX Zone 0. Besides, it can face the most extreme temperatures and even bounces off the container wall to the surface without damage and without loss of control.
