⚡ DuPont FilmTec XLE-440i Extra Low Energy RO Membrane
The DuPont FilmTec™ XLE-440i is an advanced extra-low energy (XLE) brackish water reverse osmosis (RO) element, expertly engineered for plant managers seeking high-quality permeate water with the lowest possible operating costs.
This element is characterized by its high active membrane area of 440 square feet, which allows system designers to minimize capital expenditure by using fewer elements while maximizing productivity. The XLE-440i operates effectively at ultra-low feed pressures, significantly reducing energy consumption compared to standard high-rejection elements.
Key Features:
-
Extra Low Energy (XLE): Designed for high flow and low pressure, ensuring dramatic energy savings over the element's lifespan.
-
iLEC™ Interlocking End Caps: Reduces system operating costs and minimizes the risk of O-ring leaks, ensuring sustained water quality and easier installation.
-
Wide Cleaning pH Range: Offers superior durability and the most effective cleaning performance with tolerance across a wide pH range (1–13).
-
High Flow & Rejection: Provides a high nominal permeate flow of 14,000 GPD while achieving a stabilized salt rejection of 99.0%.
