This is our smallest semi-industrial RO unit built onto a small frame to be as compact as possible. Although domestic RO units exist with similar output, this unit is built with the same electrical controls, components, and pumps as our other industrial units. This ensures that the unit, though small, can operate in more industrial applications than domestic units with similar outputs. 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.
