🔥 Geothermal Water Tanks – Resistant to Heat, Chemicals & Corrosion
Did you know that Poland has over 6 GW of geothermal potential, enough to meet up to 30% of the heat demand in certain regions? Geothermal water presents a huge opportunity — but also a significant technical challenge, due to high temperatures, salinity and aggressive chemical content. That’s why GreenTeam’s corrugated steel tanks are the ideal solution for geothermal installations in both municipal and industrial sectors.
Why Geothermal Water Requires Specialized Tanks
Water drawn from deep underground can exceed 60 °C and contain elevated concentrations of salts, sulfates, iron, manganese, or hydrogen sulfide. These properties can rapidly degrade inadequate tanks — especially those made from thin steel or plastic.
GreenTeam tanks are resistant to:
High temperatures (with optional EPDM/HDPE liners for even greater resistance)
Aggressive chemicals and high mineral content
Hydrogen sulfide and mineral-rich water
Weather exposure, UV radiation, and corrosion
✅ Technical Specification of GreenTeam Tanks
Our geothermal water tanks are built using industry-proven materials:
DelaFlex 1 mm liner or optional EPDM/HDPE liner — resistant to heat and chemicals, with 15‑year warranty on welds and UV stability
Capacities: from 5 to 3,143 m³ — suitable for small installations and large district‑heating systems alike
Modular prefabrication — fast assembly without heavy equipment
Mobility — tank can be expanded, dismantled or relocated if needed
➕ Optional Additional Equipment:
Ventilation and pressure‑relief systems
Floating or tensioned (anti‑algae) covers
Service manholes
Temperature and liquid‑level sensors
🌡 What Applications Suit GreenTeam Geothermal Tanks?
Geothermal heating plants — for hot-water storage in both closed and open loops
Food and agricultural processing plants — for process heating and energy‑cost reduction
Spas, aquaparks, hotels — for geothermal water storage feeding pools and installations
Municipal heating systems — as sustainable thermal‑energy buffers
Greenhouses and farm heating — heating soil or irrigation water to boost crop yield
🧪 Example Use‑Case
In a spa town in southern Poland, a 150 m³ GreenTeam tank with a DelaFlex liner stores geothermal water at 62 °C drawn from a deep well. The water is used to heat a sanatorium and its pool complex, reducing energy costs by up to 20 %.
🟢 Conclusion
GreenTeam geothermal water tanks offer a durable, corrosion‑resistant and cost‑effective solution where standard materials fail. With high resistance to heat, aggressive chemicals and pressure — they’re engineered for long-term performance in modern geothermal systems.
