Overview
Lithium bromide is the working medium in absorption chillers, using its strong water affinity to drive the refrigeration cycle. It is also used in pharmaceutical synthesis, batteries and organic reactions. Solution products carry specific requirements for pH, corrosion inhibitor and impurities.
- Anhydrous LiBr ≥ 99.0%
- 50–55% solution on request
- Low Cl⁻ and SO₄²⁻
Technical data
| Item | Anhydrous solid | Solution 50–55% |
|---|---|---|
| LiBr / % | ≥99.0 | 50–55 |
| Moisture / % max | 0.5 | — |
| Cl⁻ / % max | 0.10 | 0.05 |
