When we think of the digital revolution and artificial intelligence, our minds typically turn to Silicon Valley server farms or colossal semiconductor foundries in Taiwan. Few would immediately connect these global shifts with the quiet Kashubian landscape of Tuchom, situated just a dozen kilometers west of Gdańsk.
Yet that is precisely where one of the technological hearts of modern energy management is beating today. Danish engineering giant Danfoss has finalized an investment that vividly illustrates Europe’s evolving industrial landscape: a brand-new production plant set to at least double its output of district heating and cooling substations.
Behind the floor-area metrics lies a targeted response to two of the most pressing demands facing modern industry: decarbonizing municipal heating networks and quenching the surging cooling appetite of data centers.
Scaling up operations
Danfoss is hardly a newcomer to Tuchom. The Danish manufacturer has operated on this site for 15 years, and its footprint in Poland spans three and a half decades. However, the sheer scale of this latest venture elevates the facility into an entirely different league. The new complex spans over 22,500 square meters - with more than 19,000 square meters dedicated to advanced production lines, assembly bays, metal fabrication, and warehousing, complemented by nearly 3,500 square meters of modern office and social infrastructure. At full capacity, the site is slated to employ around 500 people.
The defining shift, however, lies in throughput. Previously, the Tuchom lines turned out approximately 8,000 heating substations annually - prefabricated units engineered to regulate, meter, and distribute thermal energy across building installations. Operated under HydronicS, a business unit within Danfoss Climate Solutions, the expanded facility will comfortably surpass the 16,000-unit mark per year. Integrating metal processing, component assembly, and rigorous testing under one roof streamlines supply chains, allowing the plant to respond flexibly to client orders across Europe.
Cloud computing demands cold precision
What is driving this surge in demand? For decades, heating substations were primarily associated with residential boiler rooms and municipal district heating networks. Today, that is only part of the story. While the modernization of communal utilities - accelerated by European climate targets - ensures steady baseload demand, the real catalyst is the tech sector.
Data centers running intensive cloud workloads and AI algorithms face a fundamental physical challenge: they generate immense amounts of heat. Without reliable, high-efficiency thermal management, server infrastructure simply grinds to a halt. Recognizing this, Danfoss incorporated a dedicated Competence Center for data center solutions into the Tuchom complex, alongside an experiential showroom for OEM (Original Equipment Manufacturer) partners. The facility manufactures systems engineered to precisely capture waste heat from servers and, in advanced district loops, channel it back into municipal networks to heat nearby homes. It is the closed-loop circularity long discussed across the HVAC industry, now entering volume manufacturing just outside Gdańsk.
Leading by example
In industrial architecture, it is rare to see the principle of "practicing what you sell" applied so thoroughly. Rather than relying on conventional boilers or standard commercial chillers, the Tuchom plant was engineered as a living testbed for Danfoss’s own portfolio. Heating and cooling across the entire complex are handled by a cascade of industrial heat pumps driven by Danfoss inverter compressors. The balance of plant incorporates the company's own frequency converters, balancing valves, and plate heat exchangers.
For the Danish group, currently executing its global LEAP 2030 strategy, the facility demonstrates that industrial electrification and deep decarbonization are viable, cost-effective technologies today. The site even features an interactive Decarbonization Path - a dedicated educational showcase demonstrating to visiting engineers and enterprise clients how to recover waste heat and curb losses across industrial processes. Alongside its flagship campus in Grodzisk Mazowiecki, Tuchom has firmly established itself as a showcase for pragmatic, scalable energy transition delivered from Poland.
