ENIA can supply inflatable inserts for easy and efficient sealing of the space around cables passing through ducts into pits.
They are composed of an inflatable “pillow”, of variable sizes, made of aluminium – plastic laminate. It is inflated with CO2 using a special hand held tool. Can seal against a 5m column of water and can be successfully installed under water flow. For removable it is enough to puncture and pull out with pliers.
The RDSS inflatable sealing system is a product of TYCO ELECTRONICS (RAYCHEM)
