Maintenance Considerations
notes | If air leaks into the chiller, the corrosion inhibitor is depleted as it reacts with the |
air and produces hydrogen. To maintain chiller efficiency and ensure continued | |
| corrosion protection, the lithium bromide solution must be analyzed |
| periodically to determine if corrosion inhibitor and performance additive levels |
| are within acceptable limits. This is the most important periodic maintenance |
| requirement! A laboratory test is required to determine these levels. Suggested |
| intervals for testing are once per year for |
| twice per year for chillers in continuous or critical service. Analysis of the |
| refrigerant is also recommended. Consult the chiller manufacturer for specific |
| corrosion inhibitor and performance additive recommendations. |
