ZYTEST Clinical Laboratory Ultrapure Water System

1. Power supply requirements: 220 V/380 V ±10%, 50 Hz, power 5–6 kW.

2. Feed water requirements: municipal tap water with TDS < 800 ppm, water pressure 3.0–5.0 kg/cm², water temperature 5–40°C.

3. Main process: feed water boosting system + pretreatment system + double-pass reverse osmosis system + purified water storage + EDI ultrapurification unit + ultrapure water storage system + variable frequency water supply system.

4. It can meet the water requirements of laboratory instruments such as biochemistry analyzers and immunochemiluminescence analyzers, as well as physicochemical analysis water.

5. ★ Product water quality: complies with the national standard for analytical laboratory water in China, GB/T 6682-2008, Grade I water standard. Conductivity < 0.05–0.1 μS/cm (online monitoring), equivalent resistivity ≥ 15–18 MΩ·cm. Particulates (≥0.22 μm) < 1 particle/mL. Bacterial removal rate ≥ 99%.

6. ★ The equipment adopts an integrated sheet metal powder-coated enclosed cabinet; exposed frame-type structures are not allowed. The double-pass RO system dimensions are 780 × 1800 × 1700 mm. The EDI unit is housed in an enclosed cabinet for safer use. The double-pass RO system and EDI unit can be freely combined according to site conditions, achieving a clean and attractive appearance, water-electricity separation, pipeline design in compliance with the 3D principle, and no dead-leg design. Equipment piping is connected using sanitary-grade tubing that has obtained hygienic approval for drinking water contact. Valves are made of stainless steel. A piping material inspection report shall be provided.
