Result

The reduction in temperature for both chillers provided a perpetual cost saving by reducing energy consumption by over 31,000 kWh. The equipment was also able to work at a higher efficiency, reducing wastage.

Situation

A review of the chillers at the Rottapharm facility showed that their set point temperature was set too low during the cooler months, meaning the system was wasting energy cooling water to temperatures that were not needed.

Solution

The chilled water set point was increased from 6°C to 8°C after being approved by the quality department. The change in temperature was found to have little risk to the associated equipment and cost little or nothing to implement.
