Armstrong International has announced an update to its planned expansion of its manufacturing facility in Herstal, Belgium, aiming to double its annual production capacity of industrial high-temperature heat pumps from 50 MW to 100 MW by 2027.
The expansion responds to increasing demand for industrial decarbonization solutions, supported by the European Commission’s Innovation Fund, which is allocating €1 billion to projects that electrify process heat using heat pumps and waste heat recovery.
The company finalized the acquisition of the Herstal site in mid-2025. The facility, initially set to include a 3,700 m² production area, will now be expanded to 7,000 m². The upgraded plant will integrate sustainable technologies such as geothermal energy, solar panels, and water recovery systems. It will also include administrative offices, a high-temperature heat pump test bench, and a training center.
Refurbishment is scheduled to begin in 2026. The expansion is expected to generate 77 direct jobs in Herstal and around 300 indirect jobs across the European supply chain.
“This is a significant investment for our team and a reflection of our long-term commitment to decarbonizing industry and advancing the global energy transition,” said Kurt Armstrong, CEO of Armstrong International.
Rossen Ivanov, EMEA Managing Director, cited European policy incentives and the growth of large-scale decarbonization projects as key drivers. “The new European Industrial Heat auction mechanism provides the additional funding to achieve the shorter payback periods expected by industrial plants,” said Ivanov. He added that Armstrong is also active in district heating projects that utilize excess heat from industrial sites, data centers, and hydrogen electrolysers.
Armstrong’s global manufacturing capacity for industrial high-temperature heat pumps is projected to reach 250 MW annually by 2027.
