US Water Systems Raptor 3" x 12" Ultra Low Energy Membrane Element

Here's the best opportunity to cut costs and improve efficiency with US Water Systems Ultra Low Energy - 80 PSI Reverse Osmosis Membranes - The BEST Ultra Low Energy Membrane on the Market! With an EnergyMizer membrane, your system operates at 80 psi, saving up to 40% on energy costs over systems that operate at 200-250 psi. Plus, low pressure membranes dramatically extend the life of your system because they operates at much lower pressures, putting less stress on pumps, motors, fittings, tubing and controls. It’s just like high blood pressure when you operate your system at 80 psi!

Manufactured using the industry’s leading patented membrane film technology. EnergyMizer Membrane Elements offer reliability and high performance, while delivering consistent results with high rejection rates, which equipment suppliers, distributors, and dealers worldwide have come to rely on. This is one of one of the industry’s highest flowing membranes. They are the only element on the market that operates at a pressure of 80 psi - meaning more energy savings. Energy Mizer Membrane Elements are also the best choice to counter the negative effects of cold water temperatures on reverse osmosis production.
