Seal RiGiSeal Advantages
The RigiSeal is the efficient sealing solution when the supply gas is particularly contaminated (e.g., by particles/liquids). Due to the modular design principle, the seal can be adapted on a case-by-case basis for existing machines as well as for new projects. For this purpose, the respective seal features are defined according to the prevailing operating conditions and/or the result of the failure analysis.
