Whether your system harnesses wind, sun or the Earth’s inner heat to generate power, you’re helping move the world towards 100% renewable energy. Already, within the EU almost one fifth of energy used for heating and cooling comes from renewable sources1.
Clariant’s Antifrogen fluids contribute to safe and sustainable solar thermal systems, geothermal energy applications and wind turbines.
Solar thermal collectors function on the principle of absorbing sunlight and conducting heat which is then transported away by a heat transfer fluid. To achieve optimum performance, you need not only an absorber with a high thermal capacity but also a fluid with a high thermal capacity that can withstand the stress of extremely high daytime and low nighttime temperatures, and won’t freeze in winter.
Our toxicologically harmless monopropylene glycol-based and higher boiling glycol-based solutions for highly-stressed systems are constantly flowing to protect metal components against corrosion over the long term and to virtually eliminate the risk of bursts. Our portfolio enables you to have permanent temperature conditions ranging from -50°C up to 200°C (even going up to 270°C for short periods) If needed, we also offer a special cleaning agent for solar thermal systems.
In shallow geothermal energy applications, the correct choice of heat transfer fluid is critical to for safe operation. Clariant’s monoethylene glycol-based Antifrogen GEO delivers long-lasting protection against frost, corrosion and lime scale to heat pump systems; important for installations that can save a household between 30-60% of electricity consumption compared to traditional heating and cooling systems2.
Wind power is now one of the fastest growing industrial segments in the world. Wind power farms generate between 17 and 39 times as much power as they consume3, but a turbine’s sheer scale and inaccessibility particularly when off-shore poses a maintenance challenge for operators. We are proud that our heat transfer fluids support trouble-free, low-maintenance operation. They help to keep turbine blades turning by cooling the generator and providing long-lasting protection against frost and corrosion, so that energy continues to be generated efficiently.

Antifrogen® N is a liquid, tinted pale yellow, for use as a heat transfer medium in closed hot water heating systems, heat pumps and as cooling brine in industrial refrigeration equipment. Antifrogen® N is not suitable for the use in food or pharmaceutical applications. Alternatively, the use of Antifrogen® L is recommended. The product is inhibited without the use of nitrites-, amines-, borates-, silicates- and phosphates. The optimization of the corrosion inhibition system was performed without the use of CMR-substances (cancerogenic, mutagenic, reprotoxic).
Antifrogen® SOL HT is a physiologically harmless, yellowish, clear liquid based on an aqueous solution of higher boiling glycols, which is used as a heat transfer medium in solar heating systems, also those exposed to high thermal loads. The product is inhibited without the use of nitrites-, borates-, silicates- and phosphates. It meets the requirements of DIN 4757, part 3, for solar heating systems. The optimization of the corrosion inhibition system was performed without the use of CMR-substances (cancerogenic, mutagenic, reprotoxic).
