• Human engineering design, high-strength, streamline plastic shell. • One time injection molding process case, material: Polypropylene PP. • Elegant and compact case, integrating pre-filter, RO, DI, UV, UF and terminal filter into one. • All filters are built-in, for the smallest outside space. • Top cap of pre-filters in the case can be rapidly opened to replace the pre-filters without opening the case. • With electronic pressure sensor and microcomputer controlling, the system automatically produces pure water. • Automatic stop without water, automatic stop when water tank full, automatically cutting off water when pump stopping, • guaranteeing 24 hours’ work. • Self-flushing of the reverse osmosis membrane, extend the life of RO membrane. • On-line resistivity monitor, with apheliotropic LCD display, to detect the quality of deionized or ultrapure water. • Attached portable TDS (total dissolved solid) /conductivity test pen, with dry cell design, to detect the quality of tap water • and RO water. • Different external tanks (optional) to meet every need and assure ample water-supply. • Pretreatment cartridges, RO module, ultrapure cartridges, all designed to modularization independently. Easy to • maintenance and replacement. • Pipeline and fast-plug adaptor with NSF authorization, assure high quality ultrapure water. • DOW’s RO membrane, ensure stable operation and high desalinization rate. • 4 ultrapure cartridges, with DOW’s nuclear-grade polishing resin, ensure ultrapure water’s quality up to 18.2 MΩ.cm, • with the lowest TOC dissolution. • Double wavelength (185&254nm) ultraviolet lamp module, restrain bacteria’s increase and reduce TOC. • MWCO 5000D ultrafiltration module, effectively eliminate endotoxin precise cell cultivating and IVF. • (0.45+0.1) μm double layer PES terminal disinfection filter, assure the quality absolutely axenic.
