IHC Sealing Solutions, part of IHC Merwede, has launched the zero-pollution Supreme Athmos seal which enables ships with limited draught up to approximately 5m to prevent oil from being emitted into the environment. The seal's special IHC Sealing Solutions system creates an air flow from the vent line through the seal, the drain pipe and the drain tank to the atmosphere. All the fluid that passes the lip seals is collected in a chamber between the water repellent lip seal and the oil repellent lip seal. At any given moment this liquid will fill the horizontal part of the pipe until the air-flow is blocking the supply of the air. At this moment, the special system will create a differential in pressure which will drain the liquid to the drain tank through the discharge pipe. The collection tank is located in an easy accessible place so all the liquid can be absorbed and drained under control. The special system can be used continuously or timed.
