Heat transfer fluids

coracon® heat transfer fluids for geothermal energy
More output. More sustainability. Lower costs.

40% of our CO2 emissions come from building heaters because we mainly heat with oil or natural gas although geothermal energy is available as a perfect alternative for heating and cooling. It is the future of climate management. It is renewable, inexhaustible, widely available and free from CO2, making it absolutely environmentally safe.

The overall system must be right
A geothermal energy system consists of a borehole heat exchanger, circulation pump and the heat pump’s vaporiser. The heat transfer fluid circulates in this circuit. The system’s efficiency largely relies on how efficient and stable the heat transfer fluid is.

Optimum heat transport, ideal anticorrosive and best environmental safety
Our new coracon® GEKO products ensure highly efficient operational performance, optimum system protection and allow geothermal energy in water reserves. They are based on an antifreeze and the two components of water and inhibitors acting as an anticorrosive.

Efficient and environmentally friendly
Adding an increased amount of inhibitors makes it possible to reduce the minimum use concentration (MUC) of the coracon® GEKO products to just 10%, meaning that 90% of the brine fluid can be water. In contrast: Common heat transfer fluids work with an MUC of more than 25%. The high amount of water reduces both the heat transfer fluid’s viscosity and the pumps’ required drive power, significantly decreasing the total operating costs compared to conventional cooling brine concentrates. Not to forget: All the inhibitors are fully biodegradable.

Innovative borehole heat exchanger meets innovative heat transfer fluid<br/> Together with geoKOAX GmbH, we have developed a unique overall concept for an inexpensive and environmentally compatible geothermal energy solution. The system consists of the patented geoKOAX borehole heat exchanger and of our environmentally friendly heat transfer fluid, coracon® GEKO. It is optimally aligned to the properties of the geoKOAX probe to turn innovative hardware into a perfect overall system.
