Geothermal Heat Exchangers

Geothermal heat exchangers are devices used in geothermal energy systems to transfer heat. Geothermal water is hot water obtained from underground geothermal energy sources. Geothermal sources are accumulations of thermal energy within the Earth's crust, often found in volcanic regions or tectonic plate boundaries. Geothermal water has high temperatures suitable for heating purposes. After being extracted from geothermal energy sources, this water can be utilized in heating systems. The heating process using geothermal water can be carried out through plate heat exchangers.

Plate heat exchangers and geothermal water are equipment used to heat another fluid using the heat of geothermal water. These exchangers take the temperature of geothermal water and increase the temperature of another fluid (such as water or a circulating fluid in a piping system) that needs to be heated.

Geothermal water is considered to be a sustainable energy source as it is renewable and environmentally friendly. However, the temperature and chemical composition of geothermal water can sometimes cause to corrosion or scaling in plate heat exchangers. Therefore, selecting durable and suitable materials is essential when using geothermal water. Materials like AISI316 stainless steel, AISI316Ti stainless steel, titanium alloys, and others are often preferred. These materials are resistant to the effects of geothermal water and ensure long-lasting use.

Plate heat exchangers using geothermal water can fulfill various purposes, including:

1.) Heating: Geothermal water can be used in heating systems to heat buildings or industrial plants.
2.) Hot water supply: Temperature of geothermal water can be raised through an exchanger for domestic hot water use meeting the hot water demand of buildings.
3.) Providing energy for processes: Geothermal water can be utilized to generate industrial process hot water or steam. For example, it can be used in greenhouse heating, agricultural processes, or industrial production processes.
4.) Solar energy-supported heating: Geothermal water, in conjunction with solar energy, can contribute to an energy-efficient heating system. In solar energy-based heating systems, geothermal water can serve as a backup source when solar energy is not available.

The necessary data for heat exchanger design is indicated in the table below. If these data is provided, ERK Proses offer you the most effective solution with appropriate pricing, according to technical suitability, for the desired heat exchanger.

The design and sizing of heat exchangers depend on factors such as fluid properties, flow rates, temperature differences, pressures, and other factors. These factors can influence the exchanger's heat transfer capacity, pressure loss, material selection, and energy efficiency. The required data for heat exchanger design is provided in the table above. With this data, ERK can offer you the most effective heat exchanger solution, tailored to technical requirements, at the most reasonable price.
