Description
Protegra CS Pro RO 750 is a reverse osmosis system for high-capacity purified-water production at 750 l/h. With a desalination rate of at least 98 %, minimum salt retention of 96 % and a yield of 50–80 %, it is intended for larger pure-water demands and can serve as a central building treatment plant, optionally extended into a closed pipe loop. Modern features include a 7-inch touchscreen display, removable side walls for easy access, and an energy-efficient frequency-controlled VFD pump rated for continuous 24/7/365 operation. Extended connectivity supports uninterrupted data recording via USB and microSD; three configurable changeover relays forward alarms or start-enable signals, and an optional Modbus TCP gateway plus LED status light are available. This unit from manufacturer Evoqua Water Technologies operates at 6–14 bar with a power requirement of 1,4 kW/h on a 3~/N/PE AC400V, 50/60 Hz supply (IP43). Inlet water must be hardness-free or hardness-stabilised (demand 500–750 l/h, 2–6 bar, 5–35 °C), with feed conductivity up to 2000 µS/cm and product conductivity from 40 µS/cm. Connections: feed 1,25'' AG, product and concentrate 1'' AG, drain 3/4'' AG. Height 1795 mm, width 650 mm, depth 665 mm. Included are operating manual, electrical diagram, activated-carbon/fine filter cartridge, filter key and hose set.

Questions about Protegra CS Pro RO 750 - Reverse Osmosis system, 750 l/h -NEW!
What is this article?
Protegra CS Pro RO 750 - Reverse Osmosis system, 750 l/h -NEW! is the article on this page. Luminix Health distributes Evoqua Water Technologies for laboratory use. It sits in Ultrapure & pure water systems, inside Water purification, in Instruments de précision.
A pure-water system, often by reverse osmosis and deionisation, feeds the laboratory. An ultrapure polisher takes that water to the resistivity and organic levels HPLC or cell culture ask for. Production rate and the feed water it expects are the specification. The system is not a cooler.
Laboratory water is a reagent. Tap water carries ions, organics and microbes that become part of every result they touch. A pure-water system takes most of them out. An ultrapure system, often a polisher after a first stage, is what HPLC, cell culture and trace analysis ask for. Resistivity, total organic carbon and endotoxin are different claims. A cartridge is spent when the number drifts, not when the calendar says so. The measurement of those impurities sits with NIST and the BIPM.
