iLEC Interlocking Endcaps

Virtually Eliminate O-ring Leakage and Lower Your Energy Costs

Select FILMTEC™ brackish water and seawater reverse osmosis (RO) elements are now commercially available with iLEC™ interlocking endcaps, an innovative element coupling technology that significantly enhances the performance of RO systems.

Unlike sliding couplers, the decades-old connection method still used in most of today's advanced RO systems, the iLEC technology achieves a direct, leak-tight connection between adjacent element permeate tubes, reducing the number of sealing surfaces to a single, axially compressed o-ring. This patented design dramatically reduces the potential for seal leakage, enabling sustained higher quality permeate throughout the life of the elements, and reduces energy-consuming flow resistance, resulting in lower operating costs.

Products Available with iLEC Interlocking Endcaps

FILMTEC BW30-440i

The FILMTEC BW30-440i element is a high-productivity element combining the highest active membrane area in the industry with the high rejection BW30 membrane.
FILMTEC BW30-400/34i The FILMTEC BW30-400/34i element is the ultimate element for durable, high-rejection, high-productivity performance in high fouling or challenging feed conditions, enabling trouble-free operation and a low cost of water.
FILMTEC LE-440i The FILMTEC LE-440i element is a low-energy element featuring the highest active membrane area in the industry. It enables high productivity and low energy operation, while maintaining high-rejection performance, minimizing operating expense and lowering the total cost of water for industrial and municipal applications.
FILMTEC SW30XLE-400i FILMTEC SW30XLE-400i offers an unequalled combination of productivity and rejection. This is the lowest energy seawater element available on the market, enabling lowest operation cost.
FILMTEC SW30HR LE-400i FILMTEC SW30HR LE-400i element offers very high productivity and rejection, enabling the lowest total cost of water for seawater desalination.
