Industrial Cooling : Leading Paints Manufacturer Cuts Down CO2 Emission By 72%

THE SITUATION:

Increasing levels of urbanization are projecting the acrylic paint market to grow to USD 199.88 Billion by 2024, at a CAGR of 5.4%. The usage of enamel and emulsion paints over the traditional whitewash, increasing penetration in the rural market and decorative paints are major drivers in the paint industry. Industrial processes generate large amounts of heat. It is necessary to control this temperature for an efficient process. Pumps are used to circulate cooling water through these processes to take away the heat and dissipate it through cooling towers to the atmosphere.

In this plant, cooling towers were operated manually with 2 pumps at fixed speeds, even in dynamic loading conditions. And the same was consuming an overwhelming 31.1 kW/hour. Grundfos conducted a detailed energy audit and found that the performance of the system could be enhanced.

THE SOLUTION:

Existing end-suction pumps at the site were replaced with efficient Grundfos CRE pumps. This newly-installed Grundfos CRE pumps reduced energy consumption from 31.1kw/hr to 18.0 kW/hr through its efficient permanent magnet motors with IE5 level of efficiency.

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 42% and reduce CO2 emissions by 72%. An in addition by using the auto cascading feature of CRE pumps, customers could eliminate the need for an external control panel."
