THE SITUATION:
Indian acrylic resin market grows at a CAGR of 5.1% catering to a wide range of industries like adhesives, coatings, printing inks, insulating varnishes, construction, textiles and foundries.
While manufacturing resins for industrial purposes, cooling water is circulated from condensers to cooling jackets in kettles to keep the process temperature within limits.
In this plant, pumps were manually operated at fixed speeds even when the heat load was varying across the production batches.
THE SOLUTION:
Existing pumps at the site were replaced with energy-efficient Grundfos CRE pumps. Grundfos CRE pumps with its state of the art permanent magnet motors with IE5 efficiency optimizes the system efficiency by reducing the energy consumption from 23.4 kW/hr to 18.7 Kw/hr. Further, the manual operation of the pumps was automated with Grundfos CRE pumps by utilizing its in-built auto cascading feature.
THE OUTCOME:
“Grundfos CRE pumps with its intelligent features have a great advantage of adaptability to dynamic load conditions. Thanks to the Grundfos pump audit, a new improved system with CRE pumps could bring energy consumption down by 69.5%. An in addition by using the auto cascading feature of CRE pumps, customers could eliminate the need for the external control panel.”
