Energy efficiency

Energy efficiency is one of the main contributors to reaching the Paris Agreement. By optimizing the world’s energy consumption, and being able to produce more from less, we can meet our increased energy demand and reduce CO2 emissions at the same time. In fact, according to the International Energy Agency, increased efficiency could account for more than 40% of emissions reductions in the next 20 years.

As much as 50% of today’s potential for energy efficiency saving comes from the industrial sector, and 30% can be achieved in buildings. And the solutions to enable these energy efficiency improvements already exist! At Alfa Laval, we have spent decades developing plate heat exchanger technologies that help businesses optimize energy use in their processes. Our products are used in everything from the heavy process industries to data centers, domestic heating and cooling, and much more. Our unique thermal solutions make it possible to save dramatic amounts of energy and thereby reduce carbon emissions – no matter the application!


A partnership to accelerate your sustainability

Every kW of energy saved is just as valuable as producing one new kW of clean energy. At Alfa Laval we know how to make your processes more efficient – and more sustainable. For more than 90 years, we have developed plate heat exchangers to optimize thermal transfer in heating and cooling duties.

In this video you can learn how our innovative solutions are already supporting customers’ increased need for energy efficiency and emission reduction.

Making energy efficiency a win-win for you

Meet Julien Gennetier, VP of the Energy Division here at Alfa Laval and one of the foremost industry experts on the subject of energy efficiency. In this video, Julien explains how saving energy will not only make a big difference when it comes to helping our planet. It’s also a smart way to reduce costs and boost your profitability. In other words: a win-win!

Sustainability and your plant: Energy efficiency

Are you under pressure to contribute to the overall sustainability goals of your plant? Navigating energy efficiency at your facility can often feel like an overwhelming challenge. Our free guide can help you get started.

Sustainability and your plant
Cleantech Service Watts it worth 02

Watt’s it worth?

Every year, Alfa Laval install and service millions of heat exchangers, reducing capacity needs by 100 GW.

To put that into perspective, the global wind power capacity from newly installed wind turbines was 93 GW in 2021.

Imagine what we could achieve if all industries and applications optimized energy efficiency to save energy and carbon emissions.

Service to optimize energy efficiency

Every year, the number of heat exchangers we service to optimize energy efficiency reduces our customers’ capacity needs by 50 GW. That is the amount of energy that can be generated by 10,000 wind turbines in the same timeframe.

In carbon emissions, 50 GW translates to a 25 million tonne reduction to our global footprint, or the carbon emitted by the city of London every year.

Imagine what we could achieve if the world’s industries regularly serviced their plate heat exchangers to optimize heat transfer efficiency.

Energy efficient plate heat exchangers

Did you know that plate heat exchangers are up to 50% more efficient than traditional technologies, like shell-and-tube heat exchangers?

Every year, newly installed Alfa Laval plate heat exchangers make it possible for our customers to reduce their capacity needs by 50 GW. That is enough power to heat 10 million homes in Europe for one year.

In carbon emissions, 50 GW translates to a 25 million tonne reduction to our global footprint or the annual carbon emitted by Paris.

Imagine what we could do if all industries used plate heat exchangers instead of traditional technologies to maximize heat transfer efficiency.

Waste heat recovery

What happens to the heat that your processes generate? If you’re just letting it escape into the surrounding atmosphere, you’re missing out on one of the most effective ways to improve the energy efficiency of your operations.

With the right heat exchanger technology, you can recover high temperature heat generated by industrial processes, as well as lower temperature heat captured by heat pumps in, for example, data center cooling or water treatment applications. This heat can then be used for applications ranging from district heating to producing electricity.
