Available in low- and high-temperature designs, the ECS® is a dry-running seal for emission containment and safety/backup that successfully controls VOC (volatile organic compounds) and VHAP (volatile hazardous air pollutant) emissions. The ECS provides an economical alternative to dual seals with liquid barrier systems. As a self-contained cartridge, the outer ECS is used with either a rotating or stationary John Crane primary seal and will successfully contain any nominal leakage from the primary seal. The seal also acts as a backup providing and additional level of safety during process or system upsets.
