According to Business Energy Advisor brine should be kept at a specific gravity of 1.20 to 1.22 for most efficient energy use. A hydrometer can be used to measure the specific gravity, or density relative to water. Brine should be warmed up to 60°F (apx. 15.6°C) before testing.
Specific gravity is measured relative to water, which has a specific gravity of 1.0. To adjust the specific gravity, add calcium chloride flakes to increase (mix in a barrel and add through mixing valve), or dilute the brine with water to decrease. Experts recommend testing the brine annually by a lab regularly engaged in testing arena brine samples.
Benefits:
- Insulating the brine storage tank, reduces cooling losses
- Reduced heating costs in the compressor room
Savings:
- Electricity
- CO2
