RASIRC granted US Patent for adhesive and weld-free seal for hollow fibres and ultrapure materials

The seal from RASIRC enables multiple thin wall lumens to be assembled into RainMaker humidifiers or SPA, (Steam Purifier Assemblies). The RainMaker humidifiers control the transfer and purification of water vapor directly into a carrier gas stream including inert, corrosive, and flammable gases at a wide range of flow rates for use in solar, microelectronics and other critical process applications.  

The ultrapure seal enables the RASIRC SPA to deliver steam at part per trillion level purity. The seal enables the use of high purity ionic hollow fibre membranes for steam purification.  

Jeffrey Spiegelman, RASIRC founder and president said: “It is quite difficult to assemble hollow fibers without glues or thermal bonds. Our unique method to assemble dissimilar materials allows us to create an ultrapure seal that works in high temperature and steam environments. The granting of this patent is a recognition of the uniqueness of our invention.”
