Filtration solutions for geothermal energy

Geothermal energy is the energy stored in the form of heat beneath the surface of solid earth. BOLLFILTER offers filtration solutions in both near-surface and deep geothermal energy sectors. 
In the near-surface geothermal energy sector (down to 400 m), thermal water from groundwater wells can be used in HVAC systems in combination with heat pumps. These systems can provide heating in winter and cooling in summer. In the deep geothermal energy sector (more than 400m), district heating and power generation are in focus.

BOLL & KIRCH have more than 13 years of experience in the filtration of geothermal water.

Our team can help you to choose the right filter depending on:

• The flow rate
• The temperature
• The pressure of the thermal water to be treated

As geothermal water can contain many different types of particles, differing in size or composition, the choice of the right filter element is vital.

Power plant operators as well as OEMs and PPEs in Germany, Switzerland, Austria and Hungary trust our expertise to minimize the risk of blocking production caused by coarse particles.

• Pump, pipe, valve, evaporator, preheater and condenser protection
• No blockages of the geothermal system
• Reduced maintenance requirements
