Ex Sealing Solutions

Cable Transit Frames and Sealing Systems, certified for use in potentially explosive environments (EX zones), ensure reliable and safe passage of cables and pipes through walls, floors, bulkheads, and other structural surfaces. These systems are designed to create a watertight, smoke-tight, and gas-tight barrier, making them essential in environments where safety and compliance with standards are critical. Certified according to ATEX and IECEx regulations, they are perfectly suited for hazardous environments such as energy and industrial projects, both onshore and offshore.

Our solutions are highly versatile and are widely used in sectors such as oil and gas, shipbuilding, chemical plants, and other demanding industries. Thanks to modular sealing components, these systems can be easily adapted to different cable and pipe configurations, providing maximum flexibility and efficiency. Additionally, they protect against dust, moisture, fire, and vibrations, ensuring long-term durability and minimizing the risk of leakage.

These EX zone certified sealing systems are extensively applied in shipbuilding, telecommunications infrastructure, industrial facilities, and construction projects. They offer flexible solutions that meet project-specific requirements while maintaining the highest levels of insulation, sealing integrity, and protection from hazardous factors.
