Removal of harmful gases
Seawater and seabed sediment within offshore monopile foundations contain sulfate-reducing bacteria, which produce H₂S under anaerobic conditions and at suitable temperatures. The high-voltage ring main unit installed at the base of the fan tower uses SF₆ for arc quenching, posing a risk of sulfur hexafluoride leakage.

II. Product Principle
Seawater and seabed sediment within offshore monopile foundations contain sulfate-reducing bacteria, which produce H₂S under anaerobic conditions and at suitable temperatures. The high-voltage ring main unit installed at the base of the fan tower uses SF₆ for arc quenching, posing a risk of sulfur hexafluoride leakage.
1. This hazardous gas removal system effectively removes SF₆ (sulfur hexafluoride) and H₂S (hydrogen sulfide) gases from the enclosed space; ensuring the safety of maintenance personnel working inside the tower.
2. The unit utilizes the negative pressure effect generated by a high-speed rotating impeller to draw air and SF6 gas into the fan. A flexible hose connects the air inlet to a steel pipe extending beneath the platform inside the foundation. When the fan is operating, harmful gases on the foundation platform are drawn into the fan and expelled with the airflow.
