Reaching optimal system performance
FIND OUT HOW GRUNDFOS ISOLUTIONS ENABLED H.B. FULLER TO OPTIMISE PERFORMANCE AND SAVE SIGNIFICANT OPERATING COSTS WITH ONLY 1.57 YEARS PAY-BACK TIME
H.B. Fuller is a major US adhesives manufacturing company supplying industrial adhesives worldwide. Improved system reliability
and minimum system loss were key drivers for choosing Grundfos iSOLUTIONS in its cooling tower application. Thanks to constant
temperature control, the company now has less system complexity with no need for traditional regulation valves.
SOLUTION & OUTCOME
Based on decades of cooling application knowledge, Grundfos delivered an out-the-box ready solution to H.B. Fuller with built-in
controls. This has enabled reliable process optimisation with improvements to the entire existing pump system.
EASY OPERATION
As pump and control is built to compliment each other, operation is made easier and ensures reliable process optimisation.
FULL CONTROL
Constant temperature control is built into the pump. This benefits most systems in terms of reliability, user-friendliness, process adaptability and operating efficiency.
REDUCED OPEX
Investing in intelligent control and high-efficiency pumps has improved operation, minimised downtime, reduced repair, and resulted in energy savings of 367,511.04 kWh per year.
