Industrial Cooling: Reaching Optimal System Performance [Case Study]

By: Grundfos

Find out how Grundfos iSOLUTIONS enabled a major US adhesives manufacturing company to optimize performance and save significant operating cost with a pay-back time of less than 2 years.

For the major US adhesives manufacturing company, improved system reliability and minimized 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.

  • Minimized System Loss
  • 77% Energy Savings
  • $44,970 Saved A Year

Existing System:
