GEOTHERMAL UTILIZATION
Geothermal energy offers a clean and stable power source, harnessed from the Earth’s internal heat. However, geothermal fluids are often aggressive, mineral rich, and under high pressure, requiring specialized thermal equipment.

The main challenges in this sector
The main challenges in this sector
Highly corrosive geothermal brines
Geothermal wells often produce fluids rich in chlorides, sulfates, and dissolved gases, which demand materials with high corrosion resistance to avoid rapid degradation.
Extreme temperature and pressure conditions
Steam and fluid temperatures in geothermal systems frequently exceed 150°C, often at high pressures. Heat exchangers must handle these conditions safely and consistently.
Silica scaling and fouling risks
Silica precipitation and mineral scaling can clog conventional equipment, requiring smart flow geometry and low fouling surfaces to maintain long term performance.
Critical energy recovery for reinjection or ORC
Recovered heat is key to maximize plant efficiency, whether in direct use, organic Rankine cycles, or re-injection loops.
Our involvement in the sector
Nexson delivers thermal solutions tailored for geothermal brines, vapors, and flash steam cycles, ensuring performance, reliability, and reduced maintenance in harsh underground conditions.
Extracting Earth’s energy with resilient thermal precision
Serviceable and tightly sealed
Our gasketed plate heat exchangers offer robust sealing with chemically resistant gaskets, ensuring reliable operation while allowing for fast disassembly, cleaning, and gasket replacement in case of scaling or corrosion.
Low fouling and optimized geometry
Flow dynamics within our plate designs limit silica buildup and reduce clogging risks. When maintenance is required, units can be opened quickly without dismantling piping, minimizing system downtime.
Effective recovery in binary and flash cycles
Nexson heat exchangers help extract maximum thermal energy from geothermal fluids, increasing plant performance whether used in ORC units, direct-use heating, or reinjection stages.
Custom materials for geothermal chemistry
From 316L and duplex to Titanium and high alloy options, Nexson builds each unit for the exact chemistry of your geothermal source, resisting corrosion from Hâ‚‚S, COâ‚‚, and chlorides.
