UO-D 300 C

Unit design

• Stainless steel base frame for installation of all components. The RO part is installed on a panel made of powder coated steel.
• Prefilter with 100 μm-filter cartridge and two pressure gauges,
• pipe separator BA according to EN 1717 and DIN 1988-100
• water meter controlled simplex water softener
• hardness monitoring unit limitron for continuous monitoring of feed water hardness, in case of hard water the reverse osmosis shuts down.
• Special inlet filter with 5 μm-filter cartridge with two pressure gauges filled with glycerin,
• high pressure pump rotary-vane type,
• high performance wound module(s) with PA/PS composite membranes in stainless steel pressure vessel.
• Valves such as sampling valves for feed water and permeate, inlet solenoid valve, valves to regulate the flow rate of permeate and concentrate.
• Pressure sensors for pump feed pressure and operating pressure.
• Flow indicator in the display for permeate and concentrate.
• Conductivity measurement of permeate with temperature compensation.
• Screw connection for a manual cleaning unit.
• Connecting cable (3 m) with 16A – 6h CEE three-pole plug.
• Unit completely wired and pre-assembled and ready for installation. Electrical equipment in accordance with VDE 0100 part 600, VDE 113 part 1.

Microprocessor control RO digital

• for fully automatic monitoring and control of Reverse Osmosis Unit.
• Process visualization with central display of operational status and data (analogue und digital values ) and hours of operation on 4-line, backlit LCD text display. Simple menu-driven operation of the controller with 6 buttons.
• Automatic logging of relevant operating data (analogue and digital data, 1960 data sets), storage interval programmable.
• Highest operational safety due to adjustable alarms and limits of the operating parameters with selectable system response.
• Operating conditions: permeate production, permeate rejection / recirculation, concentrate displacement / flushing, intermittent flushing when system is idle, shutdown by an external signal.
• Analogue inputs: permeate conductivity (temperature compensated) permeate temperature, feed water, operating and concentrate pressure, flow rates of permeate and concentrate, calculated feed water flow, 2 additional programmable analogue inputs (e.g. for pressure, flow, level measurement).
• Digital Inputs: RO-unit start, RO-unit stop, hard water / motor protection, external stop, 3 universal inputs (free configurable)
• Analogue outputs: 2 universal outputs 4-20mA, e.g. for DDC.
• Digital outputs: high-pressure pump, valve outputs 3x (24 VDC) for example for feed water, concentrate flushing, permeate rejection or recirculation, collective fault indication as a floating changeover contact, universal output.
• LED indicators for power and fault, fault alarms as plain text in the display.

• Permeate recirculation PR500/24
• VSE Blending device
