| Features |
■ Integratespre-treatment, 2-stage RO system, an EDI module, a 150L stainless steel RO water tank, a 280L stainless steel EDI pure water tank, and a pure water distribution loop into a single system, coveringthe complete water purification process from raw water pressurization to pure water circulation. ■ Delivers high-purity water (resistivity ≥ 15 MΩ·cm) at low cost, meeting the demands of central lab water supply systems; Compatible with optional DI ion exchange cartridges and UV oxidation modules. ■ Accommodates UF ultrafiltration and MF microfiltration modules to produce ultrapure water (resistivity up to 18.2 MΩ·cm, low TOC, sterile, pyrogen-free); conforms to Type I water standard per GB/T 6682-2008, GB/T 33087-2016, ASTM, CAP, CLSI, EP, and USP. | |
* The value is affected by water temperature, feed water quality, and total contaminant load.
