Where we make impact

Making sustainability possible

It’s a thrill to see our technology out in the world, especially when it’s used in innovative projects that help to build a sustainable future. Here are two examples of how our heat exchangers make renewable energy feasible.

NOx and particulate matter than diesel alternatives. SWEP supplied a range of heat exchangers to the project in Lodi, Lombardy. As a cheaper alternative to plate-fin exchangers, they made the plant economically feasible – it’s doubtful whether a plant of this scale would have been affordable without the technology that we delivered. Our heat exchangers are used to cool gas to -160°C for liquefaction. Construction is underway on a 70,000 m³ pit thermal energy storage (PTES) solution in Høje Taastrup, Copenhagen, and SWEP have provided brazed heat exchangers at the heart of the site. The plant will be essentially a thermal battery, drawing in heat from the transmission grid, then discharging it throughout the district heating network whenever there is a demand for it. Once the full project is up and running, it will serve half a million district heating customers – saving up to 15,000 tonnes of CO e 2 annually. Enabling thermal energy storage in Denmark

Powering the biogas revolution in Italy

The use of renewable fuel in vehicles is an important part of Europe’s decarbonization pathway, and we’re delighted to have contributed to Italy’s first liquefied biomethane plant, which began operating in November 2020. The plant uses domestic and agricultural waste to create biogas, which is then purified to produce liquefied biomethane. Biomethane has the same properties as liquid natural gas (LNG), so it can be used in existing gas infrastructure. More and more trucks are converting from diesel to LNG, so the plant will be especially important for increasing the use of renewables in the transport sector. Biomethane delivers multiple environmental benefits. As well as drastically reducing CO emissions, it releases far less 2

The plant was designed and built by Criotec Impianti Spa.
