DESCRIPTION:

The R&D Specialties’ Series 150 reverse osmosis microprocessor controller features an alphanumeric backlit LCD to display operating conditions, and provides adjustable time delays and set points to accommodate varying field conditions.

The Series 150 controller displays the permeate TDS/Conductivity, water temperature, and operating hours along with the operating status of the RO unit. The Series 150 monitors low and high pressure switches, tank levels, and pretreatment equipment. It provides relay outputs for the RO high pressure pump, inlet solenoid valve, membrane flush solenoid valve, and optional relays for permeate divert or remote alarm and auxiliary output.
