FILMTEC™ Membranes
iLEC™ Interlocking Style Seawater Elements for Industrial Systems

A variety of FILMTEC elements are now available with iLEC interlocking end caps, an innovative element coupling technology that significantly enhances the performance of RO systems.  Instead of using interconnectors to couple membranes end-to-end within a vessel, interlocking end caps twist directly together, reducing the number of sealing surfaces to a single axially compressed O-ring.  The design reduces the potential for seal leakage, enabling sustained higher quality permeate, and reduces energy-consuming flow resistance, resulting in lower operating costs.
