Coolant water testing is essential to prevent engine overheating, corrosion, scaling, and deposit formation. Regular monitoring ensures the cooling system operates at peak efficiency, extends equipment life, and meets OEM and regulatory requirements.
The following parameters are typically monitored for coolant water quality as per marine engineering best practices and international guidelines:
| S NO. | TEST PARAMETERS | METHOD |
|---|---|---|
| 1 | pH | APHA 4500 H+B |
| 2 | Glycol Concentration | Refractometer / ASTM D3321 |
| 3 | Reserve Alkalinity | ASTM D1121 |
| 4 | Chlorides | APHA 4500-Cl |
| 5 | Sulphates | APHA 4110B |
| 6 | Hardness (CaCO₃) | APHA 2340B |
| 7 | Dissolved Solids | Gravimetric Method / TDS Meter |
Sample Volume: Approximately 500 mL is required for coolant water sampling.
