Baltics Immersion Cooling Market to Quadruple by 2035 Amid Hyperscale Data Center Boom
The Baltics immersion cooling tanks market is projected to grow 18-25% annually through 2035, driven by hyperscale data center construction, primarily in Estonia, Latvia, and Lithuania. The region is largely import-dependent, sourcing tanks from Western European and Asian manufacturers. Demand is shifting from early adopters to mainstream deployments in financial services, telecom, and government data centers.
Key Takeaways
- Baltics immersion cooling tank demand will increase 3-4 fold by 2035, with an 18-25% CAGR through 2030, then moderating to 10-15%.
- The region is over 90% import-dependent for tanks, sourced primarily from Western European and Asian manufacturers; no commercial-scale domestic production exists.
- Single-phase immersion tanks constitute 65-75% of unit demand, favored for lower operational complexity, while two-phase systems are growing in HPC environments.
- Estonia leads regional demand (45-55% unit volume), followed by Latvia (25-30%) and Lithuania (20-25%), with Lithuania showing the highest growth rate at approximately 22%.
- Supplier qualification and input cost volatility (stainless steel, dielectric fluids) are key challenges, leading to 12-20 week lead times and 8-15% annual price fluctuations for tanks.
Additional Context
The global immersion cooling market reached $931 million in 2026, with projections to hit $4.9 billion by 2033 at a 27.1% CAGR, indicating a broader trend beyond the Baltics (mgrid.org, March 2026). Single-phase systems hold an 80.9% market share globally, reflecting the Baltics' preference (mgrid.org, March 2026). This market growth is partly driven by AI workloads exceeding 100 kW per rack, where traditional air cooling becomes inefficient (mgrid.org, March 2026). Major players are innovating; Asperitas launched a new Direct Forced Convection immersion cooling tank in May 2026, capable of cooling beyond 3.6kW per u (datacenterdynamics.com, May 2026). Similarly, Vertiv introduced an immersion cooling pod supporting 25kW to 240kW per system in November 2025, operating with a PUE of 1.08 (datacenterdynamics.com, November 2025). ZTE also announced its IceTank, processing over 2000W per node using oil-based or fluorinated liquids (datacenterdynamics.com, May 2026). These product introductions suggest increasing competitive pressure and technological advancements aimed at addressing the mounting thermal demands of modern data centers.
