ABB helps Sapa Heat Transfer AB to optimize the energy use

2013-04-19 - Energy study showed saving potential worth millions
Sapa Heat Transfer has comissioned ABB to conduct an energy study at one of the company’s cold rolling mills, with a main focus on various auxiliary equipment. The analysis showed a large energy-saving potential. In addition to a 3 percent reduction of the rolling mill’s electricity use, large savings opportunities were also identified in lowering waste heat losses and reducing demand for cooling water and compressed air.

Sapa Heat Transfer is a world-leading supplier of aluminum belts mainly for different types of heat exchangers to cars and trucks. Sapa is committed to be a part of a sustainable society and makes continuous efforts in the area of sustainable development . Its energy policy states that the company shall work strategically to eliminate energy waste in its processes and buildings, which involves doing overhauls of older equipment in different parts of the operations that are assumed [suspected] to use large amounts of energy.

ABB was given the assignment to analyze the energy use of the auxiliary equipment in one of the cold rolling mills and to recommend energy-saving measures, including calculations of the full savings potential and the cost of their implementation. ABB also provided training in how to conduct a major machine equipment energy study as part of this solution .

”We know that our old machines are less energy efficient but we don’t know exactly where and how big the waste is”, said Michael Sundström at Sapa Heat Transfer. We engaged ABB to help us identify possible savings and to give us recommendations of savings measures including calculations of how much energy we can save when the measures are implemented.

”Following the analysis, we can see that large savings can be reached for one single machine, which indicates there is a huge savings potential for the entire process. The fact that ABB’s energy experts executed the data collection and the analysis efficiently and in a structured way together with our people was an additional benefit [gave ABB an extra mark]”, commented Sundström.

ABB’s energy management services help customers to save energy, from defining energy waste in equipment and buildings, to providing recommendations for how to prioritize and select the right measures to reach the highest possible savings. Examples include replacement and streamlining of processes and machine equipment as well as management strategies and employee behavior. Improving energy efficiency will reduce environmental impact and, at the same time, improve competitiveness.
