Organic Acid Coolant Concentrate
Long-life concentrate for mixing with controlled-quality water, for engines whose builder specifies organic acid inhibitors.
Features
- Long inhibitor life with low deposit formation, which keeps heat transfer surfaces clean over a long fill.
- Mixed on site with deionised or low-chloride water; the mixing water is part of the specification, not an incidental.
- Suited to fleets that can control their mixing and testing, because the saving over ready-mixed is real but depends on discipline.
- Strength checked with a refractometer at fill and at each service, and recorded against the machine.
- Not to be mixed with nitrite-containing coolants without draining and flushing first.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Mix ratio | 40 - 60 concentrate | % | sets freeze protection and heat transfer |
| Freeze protection at 50 percent | -37 | degrees C | the figure behind a winter readiness check |
| Mixing water specification | deionised, chloride below 25 mg/l | hard water forms scale and consumes inhibitors |
