Production of your own coolant
When producing your own coolant, we recommend:
- Water-based coolant
- Use of distilled water
Parameter | Unit | Measured value |
|---|---|---|
pH | - | 6.5…7.5 |
Water hardness | mmol/l | 1.2…2.5 |
Chloride concentration | ppm | < 100 |
Sulfate concentration | ppm | < 100 |
Conductivity | μS/cm | < 500 |
Particle size | μm | ≤ 100 |
- The addition of suitable biocides is recommended to prevent biological deposits.
- To prevent corrosion in the cooling circuit, the addition of a suitable corrosion inhibitor is strongly recommended. If the inhibitor content is higher, the performance of the component to be cooled may be reduced.
- Recommendation: Concentration of corrosion inhibitor 25 %
- The mode of action of a corrosion inhibitor is based on the formation of a protective layer on the chiller unit surface. If components are replaced, e.g. in the event of a repair, there is a risk that the corrosion inhibitor still contained in the cooling circuit cannot build up a sufficient protective layer.
- Recommendation: When replacing the motor in the cooling system, we recommend renewing the coolant.
