Our semi-industrial range RO units are built with 4040 membranes and range from 200–1,000 L/h. The units have custom-built electrical control boxes that include over- and under voltage protection, a delay timer, a contactor, pre- and post-low-pressure switches, and a cable float switch.
We offer three options: standard unit, coastal-friendly, and brackish water. Low-energy membranes are used on our standard models to ensure low operating pressures and low power consumption. The coastal-friendly and brackish-water units are built with stainless-steel screws, fiberglass electrical panels, and fiberglass membrane housings. There is also space on the frame to mount a post-filtration assembly and pre-filters, reducing the footprint of the purification unit.
