- MAXIMISED RELIABILITY
- €15,500 SAVED A YEAR
- 52% ENERGY SAVINGS
Discover how Grundfos iSOLUTIONS enabled a packaging manufacturer to significantly improve process operation and operating costs in its cooling application.
For a UK packaging manufacturer, cooling system reliability and control is essential. That’s why it chose Grundfos to supply intelligent pumps and controls in a retrofitting project that resulted in huge operational savings of €15,500 a year.
Existing pumps details:
3x end-suction pumps, IE2 motors
Existing control mode:
Duty/duty/standby, fixed speed
Existing operation mode:
Controlled by pressure rather than differential temperature
New system details:
3x Grundfos NBE 65-200/198 + Control MCP-E + Grundfos DPI
New control mode:
Temperature control – differential temperature
New operation mode:
Pumps will adjust their speed depending on how much flow is needed to guarantee a constant and stable cooling loop temperature
Solution & outcome
A new pump system from Grundfos was selected due to its differentiated built-in control mode based on constant differential temperature. Keeping a dT of 3 degrees – as requested by the customer – cooling capacity was kept the same, but Grundfos products reduced the flow to ensure optimal thermal exchange, thereby minimising the losses of the previous system.
Reliable process optimisation of existing pump installations was achieved by our out-the-box-ready solution, featuring built-in controls based on our deep application knowledge.
Intelligent pumps with integrated frequency converters brought a unique array of built-in pump functionalities that benefit most systems in terms of comfort, user-friendliness, process adaptability, connectivity and operating efficiency.
The final delivered package improved operating performance and ensured corresponding savings in energy use and maintenance. Grundfos iSOLUTIONS guarantees temperature setpoints never deviate from what’s necessary to ensure optimum operating conditions.
