China's national standard for cold plate liquid cooling now defines cleanliness as five measurable numbers. COOLPiRE builds the instruments that produce those numbers — and the record that survives an audit.
Suzhou Coolpire Intelligent Technology Co., Ltd. · Liangcai Zhihuigu, 20 Fuze Road, Suzhou Industrial Park, Jiangsu, China. Engineering prototype of the LC-CLEAN-100 is complete and under performance validation.
Illustrative interface. Values are not measured data.
Actual reports include full process curves, calibration data and sample IDs.
GB/T 48023—2026 requires that secondary-side piping be flushed with deionised water after pressure testing, for not less than 24 hours, and that water quality be tested afterwards. Both requirements use mandatory language.
| Parameter | Post-flush limit (Annex B.3.2) | In-service limit (Annex A) | How we handle it |
|---|---|---|---|
| Conductivity | ≤ 10 μS/cm (25 °C) | by agreement | Continuous online · gates release |
| pH | 5 – 7.5 (25 °C) | ±1 from baseline | Continuous online · gates release |
| Turbidity | ≤ 5 NTU | ≤ 20 NTU | Continuous online · gates release |
| Copper | ≤ 0.5 mg/L | total Cu ≤ 5 mg/L | Sampling port · chain of custody |
| Iron | ≤ 0.5 mg/L | total Fe ≤ 5 mg/L | Sampling port · chain of custody |
Two carts, networked. The release certificate issued by the LC-CLEAN-100 is the only key that unlocks filling on the LC-FILL-200. This is a hardware interlock, not a procedural recommendation.
Chemical cleaning and deionised water circulation, with online conductivity, pH and turbidity measurement. Issues a release certificate when limits are met.
Evacuates before filling to eliminate trapped air. Spent coolant is captured in a closed circuit and routed to licensed disposal.
Which tells you something: built-in filtration intercepts. It does not restore.
If the data is going to be signed, the instruments have to hold up first.
Key instruments support third-party calibration; calibration records are issued with the report.
