Components
Frame
- The frame is the transit opening itself and provides enough structural strength to manage the compression force when closing the seal
- The frames are welded, bolted to or cast into the structure
- There are different sizes of the opening, i.e. the packing space
- Openings can be added to each other, horizontally and vertically, to make one big combination frame with several openings
Modules
- Multidiameter™ is the key innovation in our solutions
- The layers can be removed to adapt the hole size to the actual size of the cable or pipe passing through
- Roxtec RM modules come in 10 basic sizes
Lubricant
- Natural tallow is used to lubricate the sealing modules, the compression unit and the inside of the frame
- The lubricant ensures movement in the frame during compression, which is essential for an even compression and thereby correct sealing performance
Stayplates
- The stayplates shall be inserted between the module rows
- The function of the stayplate is to provide pull-out resistance for the sealed cables or pipes and to improve leak-tightness performance
Compression unit
- To accomplish a tight seal, a compression unit is used to seal the installation of cables or pipes, modules and stayplates
- When the bolts are tightened the compression unit expands and compress the modules to create a tight seal
- The wedge clip is used to verify the compression
