Refrigeration and Cooling efficiency in dairy
In dairy, refrigeration and cooling is a major energy cost and a strong efficiency opportunity. Refrigeration and cooling are major electricity users whose efficiency degrades with condenser fouling, refrigerant problems, poor controls and oversized, throttled pumps and fans. Maintaining heat exchange, optimising set-points and speed-controlling auxiliaries cut the load.
Why it matters in dairy
Dairy processing pairs intense thermal duties — pasteurisation, evaporation, spray drying, sterilisation — with refrigeration and frequent clean-in-place cycles. Energy and water are major costs, and hygienic, continuous operation makes reliability and efficiency monitoring especially valuable.
Cooling is often critical to product and process, runs long hours, and degrades quietly as condensers and evaporators foul and controls drift. Because the efficiency loss is hidden in rising energy per unit of cooling, monitoring and maintenance protect both cost and uptime.
The efficiency levers
- Keep condensers and evaporators clean
- Optimise set-points and avoid overcooling
- Speed-control compressors, pumps and fans
- Maintain refrigerant charge and controls
- Recover reject heat where there is a demand
