PRESS RELEASE

Aalborg hc systems continues the activities of the low temperature (LT) division of Aalborg CSP — with the same comprehensive expertise and experience, on a stronger platform for growth across Europe.

The Alois Müller Group has founded Aalborg Heating & Cooling Systems ApS (known as aalborg hc systems) who then acquired the LT-Division of Aalborg CSP. The team, the projects, the accumulated expertise of close to 40 years, including the patented pit thermal energy storage lid technology are all transferred to the new company.

For clients and partners, nothing changes. Aalborg hc systems continues to design and deliver complete thermal systems for district heating networks. Integrating heat from geothermal sources, wastewater, seawater, air and waste heat recovery into existing infrastructure, and engineering the full system around it. With a strong reference base and a growing pipeline across Europe, the company is ready for what comes next.

The right moment to move forward

“We have an extensive pipeline, and the market is moving in our direction.With the Alois Müller Group we have a partner who already knows what we do, has the resources to back us, and genuinely wants us to grow. We tap into their network, their EPC capacity, and their financial strength, and together we can both move forward faster than we could before.”

– Jes Donneborg, CEO of the new company.

A parent on paper. An older sibling in practice

Behind aalborg hc systems now stands the Alois Müller Group, a German family-owned industrial group founded in 1973, with around 1,100 employees across 16 locations in Europe. What aalborg hc systems needs and does not yet have, the Alois Müller Group puts at its disposal.

“Aalborg hc systems has something that takes decades to build. Our job is simply to give them the platform to do more of it. They bring the expertise. We bring the network, the capacity, and the financial backing. That is exactly how it should work”

– Andreas Müller, CEO and owner of the Alois Müller Group.

A market on the move, and a company ready for it

The markets are moving. Germany’s new heat planning legislation is driving one of the largest waves of district heating investment in European history. The Nordics are accelerating away from fossil-fuelled heat. Central and Eastern Europe is investing seriously in network renovation. Aalborg hc systems with its home market in Denmark, active pipeline in Germany, growing presence across the Baltics, Poland and Central and Eastern Europe, is ready, and has now the strength to exploit it with a partner, who has the muscle to match the ambition.

Together, the two companies are positioned to play a meaningful role in sector coupling, combining the patented PTES technology with heat pumps as Europe electrifies its heat.

FAQ

What does aalborg hc systems deliver?

aalborg hc systems designs and delivers integrated heating and cooling systems in new and existing networks.

This includes:

  • large-scale heat pumps
  • thermal energy storage (TES and PTES)
  • integration of multiple heat sources

The focus is on complete system solutions, not standalone technologies.

Can you integrate into existing district heating plants?

Yes. Most projects involve integration into existing infrastructure. aalborg hc systems connects new technologies to:

  • existing networks
  • boilers and CHP units
  • available heat sources

The result is a coordinated system upgrade, not a replacement of existing assets.

Do you act as EPC contractor?

Yes. aalborg hc systems delivers projects on an EPC basis.

This covers:

  • engineering and system design
  • procurement and supplier coordination
  • construction and commissioning

The responsibility remains with one party from concept to operation.

Which heat sources can you integrate?

aalborg hc systems integrates multiple heat sources within one system, including:

  • wastewater
  • geothermal energy
  • ambient air
  • industrial excess heat

Solutions are designed as source-agnostic systems, optimised for local conditions.

What do you need to get started?

A project can start with a limited set of data:

  • heat demand profile (load curve)
  • supply and return temperatures

Based on this, aalborg hc systems defines a first system concept and integration approach.
