Danish Firm's Heat Pumps Scale to 50 MW for Green Heating

Heating factories, neighborhoods, and commercial buildings just got a major climate-friendly upgrade.

Advansor, a Denmark-based manufacturer, has launched SteelXL Heat Pumps that deliver up to 4.8 MW of heating power per unit. Multiple units can work together to reach more than 50 MW, enough to heat thousands of homes or large industrial facilities.

The game changer? These systems use CO2 as their refrigerant instead of synthetic chemicals that harm the environment. They pull heat from the air and amplify it, producing three units of heat for every unit of electricity consumed.

That efficiency matters enormously for cutting carbon emissions. Industrial heating and district heating networks currently burn massive amounts of natural gas and coal. Switching to electric heat pumps powered by renewable energy could eliminate those emissions entirely.

The new systems deliver hot water at temperatures up to 95°C, hot enough for food processing plants, paper mills, and other industrial applications. They work in temperatures ranging from negative 14°C to 45°C, making them viable across different climates.

Advansor designed the units to be fully customizable for complex installations. Each heat pump measures 18 meters long and weighs up to 33 tons depending on configuration. Three standard sizes handle different capacity needs, from 600 kW up to 4.8 MW.

The Ripple Effect

District heating networks serve millions of people across Europe and are expanding globally. Converting these systems from fossil fuels to electric heat pumps represents one of the fastest paths to decarbonizing buildings.

The technology works especially well in places with cold climates and renewable electricity. Scandinavia leads the world in district heating adoption, with some cities already transitioning their networks to heat pumps powered by wind energy.

Manufacturing all happens in Denmark, where Advansor operates 15,000 square meters of production space. The company already serves customers in more than 30 countries and has been refining CO2 heat pump technology since 2006.

Industrial customers can combine these units like building blocks, scaling capacity as their heating needs grow. The modular approach means facilities can start smaller and expand without replacing equipment.

Clean heating at this scale proves that climate solutions can match the power of fossil fuel systems while slashing emissions to near zero.
