1. Performance and Application
This product is an operation‑maintenance agent for central‑air‑conditioning cooling‑water systems. It effectively inhibits precipitation of scale‑forming ions in cooling water and suppresses mass reproduction of bacteria and microorganisms that generate biological slime. It keeps condenser copper tubes, system pipelines and cooling towers clean.
Formulated with anti‑corrosion components, it protects various metal parts inside air‑conditioning systems against corrosion damage, extending service life of central air‑conditioning units.
It maintains cooling‑water system in good operating condition, substantially cutting electricity cost, maintenance expense and cleaning cost and bringing considerable economic benefits.
Suitable for routine maintenance of central‑air‑conditioning cooling‑water circuits. It prevents scale and biological slime on heat‑exchange surfaces, ensures stable system operation and prolongs equipment service life.
2. Technical Specifications
| Item | Index |
|---|
| Appearance | Reddish‑brown transparent liquid |
| pH (1 % aqueous solution) | ＜7.5 |
| Flammability | Non‑flammable |
| Density (20 ℃, g/cm³) | 1.10±0.05 |
3. Usage Method
- Dosing amount: Add 200 g product per ton of total system water. Add full dosage in one‑time from cooling‑tower collection tank for normal system operation.
- Blow‑down: Blow‑down once per week, blow‑down rate:15‑25 %. Blow‑down cycle and rate can be adjusted according to cooling‑water control indicators; higher blow‑down rate shall be adopted in hot summer seasons.
- Dosing cycle:
① Regions south of Yangtze River:
Supplementary dosing every ~10 days from June‑October; every 15‑20 days for other seasons, dosage calculated as 200 g per ton system water. Based on 8‑month annual operation, perform supplementary dosing 14‑16 times per year.
② Regions north of Yangtze River:
Supplementary dosing every 5‑7 days from July‑September; every 10‑15 days for other seasons, dosage calculated as 200 g per ton system water. Based on 5‑month annual operation, perform supplementary dosing 20‑24 times per year. Shorten dosing cycle and increase dosing frequency under high‑hardness & high‑alkalinity water quality.
4. Notes
- For air‑conditioning systems with poor makeup‑water quality or groundwater feed, determine blow‑down volume according to cooling‑water indicators; dose proportionally against makeup‑water volume.
- Store in sealed cool‑ventilated location; tightly close container lid after dosing, avoid open storage.
- Slight layering may occur after partial volatilization. Shake thoroughly before use; product performance remains unaffected.
- Packed in 25 kg plastic drums. Stable physicochemical properties. Store in cool place. Shelf‑life:12 months。
