CTS20 secondary seal

The CTS20 is an independent rim mounted secondary seal. As such it will still seal off the rim space even if there would be an issue with the primary seal underneath. It consists of metal compression plates, Behind these compression plates a continuous vapor barrier is installed which provides excellent vapour tightness and ensures a very effective seal. At the tip of the compression plates is a rubber sealing lip profile, providing the seal against the tank shell. The CTS20 seal will be designed according to API 650 and all other relevant (inter)national requirements such as EN 14015 and EEMUA 159.
