| Unit completely wired and pre-assembled and ready for installation. Puritron 500 microprocessor control system for fully automated monitoring and control of the reverse osmosis unit with two-digit alphanumeric display LCD of permeate conductivity, forced stop and full tank. Alarm signals: low pressure, hard water and high conductivity. LEDs for operation and disinfection. Input (low voltage) for level control with 1 or 2 float switches, hardness monitoring unit. The Puritron 500 controller includes control functions for the hardness monitoring unit, shut-downs by external alarm signal (forced stop, regeneration). During the regeneration cycle of the water softener, no permeate is produced. The softeners of the types 20 and 40 combi are timer-controlled, the types 80 through 350 combi are water meter controlled. The integral system makes piping of the individual components at site unnecessary. |
