Solution & Outcome
Based on decades of cooling application knowledge, Grundfos delivered an out-the-box solution with built-in controls. This has enabled reliable process optimization with improvements to the entire existing pump system.
As pump and control is built to compliment each other, operation is made easier and ensures reliable process optimization.
Constant temperature control is built into the pump. This benefits most systems in terms of reliability, user-friendliness, process adaptability, and operating efficiency.
Investing in intelligent control and high-efficiency pumps has improved operation, minimized downtime, reduced repair, and resulted in energy savings of 367,511.04 kWh per year.
