Protegra OF 3000 - Reverse Osmosis, 3000 l/h

The Protegra OF 3000 reverse osmosis system The Protegra OF 3000 cost-effectively produces larger quantities of deionized water. Equipped with high-quality components and an intelligent control system, the system must be connected to a tank with level monitoring to control production. The system provides high purity water with the advantage of continuous operation. Production runs automatically in two operating modes. Product features and benefits: - With energetically economical and high performance reverse osmosis membranes, a high output of pure water is achieved with a high salt retention rate at the same time. This minimizes the energy requirements and reduces water loss. - Before each standby an automatic system flush is performed to reduce the ion concentration at the membranes which increases the life and reliability of the system. - A microprocessor controller monitors the pure water quality and the status of the system. Exceeded values, such as expired maintenance intervals and water quality are displayed as alarm messages. - The limit values for conductivity and flow rate of the pure water can be set individually. - The system is structured clearly and can be operated from all sides for service purposes. - The system is low-maintenance. Pure water production: Reverse Osmosis - Feed water solenoid valve - Pressure regulator - Conductivity sensor for feed water (cell constant c=1.0) - filter housing includes four 20" filter cartridges, 5 µm - Pressure switch for feed water - Stainless steel pump (1.4401/1.4301) - Pressure sensor for operating pressure - 3 Reverse osmosis modules 8" from polyamide/polysulfone with GFK cylinders and end caps - Regulator for concentrate flow to drain and return flow - Three flow sensors for pure water and concentrate - Conductivity sensor for permeate (cell constant c=0.2) - Quality dependent permeate distribution valve Microprocessor Control: - Located on the front of the system - System status - Conductivity of feed water and permeate - Volumetric flow of pure water and concentrate - Reminder service and filter change - Alarm indicator for: low flow feed water, out of range conductivity, flow rates and tank volume - Tank level indication in Percent, three options for unit to switch ON or OFF. Pump protection against running dry for pure water - Connection for common alarm to BMS with adjustable time interval (optional single alarm possible) - Time schedule for concentrate to drain and module rinsing - Multilingual (German, English) - RS232 interface, with optional software for further data processing Delivered with: - Operating manual - Electrical diagram - CE certificate Connection possibilities: - Potential free contact for common alarm - Booster pump start/stop function with dry-run protection and interval operation - Feed water hardness monitor. In the event of hardness breaking through the unit switches off to prevent blockage of the RO membranes Optional: - Reminder for service intervals (potential free contact) - UV-disinfection kit with interval operation - Timer switch for use in connection with pressure booster pump Feed water specifications: Flow rate: 4000 - 6000 l/h Pressure: 2 - 6 bar Conductivity: < 2000 µS/cm TDS: 1000 mg/l CO2: < 20 mg/l Total Iron: < 0.1 mg/l Free Chlorine: < 0.1 mg/l Temperature: 5 - 30°C Softened or hardness stabilized Performance specifications: Delivery flow rate at 15°C: 3000 l/h Salt retention: 98 % Recovery rate up to: 75 % TOC: < 30 ppb Bacteria reduction: > 99 % Technical data: Operating pressure: max. 14 bar Mains input: 3 x 400 V, 50 Hz Power consumption: 5.5 kW/h Ambient temperature: 5 - 35°C Fuse: 16 A Feed water connection: R 1-1/2" male BSP Permeate water connection: R 1-1/2" male BSP RO permeate, drain connection: R 1-1/2" male BSP Pure water back-pressure: 1 bar Dimensions and Weight: Height: 1900 mm Width: 3900 mm Depth: 960 mm Weight: 345 kg Please note: The unit accepts a feed water salt content of 1000 mg/l, equivalent a conductivity of 2000 µS/cm at 15°C.
