I. Replacement Cycle Standards
1. Normal Industrial Environments
Replace cooling water every three months (purified or distilled water is recommended).
If water quality is poor (e.g., contains a high concentration of impurities), replacement should be reduced to once a month.
2. High-Load Operating Conditions
When the equipment operates continuously at temperatures above 70°C, replacement is recommended every two months.
If turbidity or sediment is detected in the cooling water, replace it immediately.
II. Key Points for Water Quality Management
1. Recommended Water Source
Must use purified or distilled water (to prevent scale and bacterial growth).
2. Water Quality Monitoring
Test cooling water conductivity monthly (recommended: <50 μS/cm).
Clean water tank sediment regularly (recommended quarterly).
III. Maintenance Procedures
1. Replacement Procedures
After shutdown, drain old water → clean water tank → refill with new water → exhaust inspection.
2. System Protection
Add antifreeze (ethylene glycol concentration 30%-50%) in winter.
Drain the cooling system after extended periods of inactivity.
