Clariant sets new limits in solar heating

Muttenz, Switzerland (ots) - Clariant creates new possibilities
for the alternative energy market to achieve effective, long-life
protection for solar and geothermal systems with the addition of
Antifrogen(R) SOL HT and pioneering Antifrogen(r) GEO to its trusted
family of heat transfer fluids.

Antifrogen SOL HT enables highly-stressed solar heating systems
with high thermal loads to work effectively over the long-term,
whether facing a permanent usage temperature of up to +200 °C or
operating at lows of -23 °C. New Antifrogen GEO is a cutting-edge
development for near-surface geothermics, combining protection with
environmental benefits.

Antifrogen SOL HT is a specially designed heat transfer fluid that
combines high-level corrosion protection with superior thermal
stability over a broad temperature range. Developed in response to
the increasing use of vacuum collectors, which have a high stagnation
temperature of +270 °C and above, Antifrogen SOL HT offers protection
to idle systems at temperatures in excess of this and at permanent
operating temperatures of up to +200 °C.

Higher boiling glycols in Antifrogen SOL HT prevent similar
evaporation of traditional, low boiling ethylene or propylene
glycol-based fluids from occurring at such high temperatures. By
preventing evaporation and the associated build-up of salt-like
residues, the potential for operating problems and maintenance is
reduced.

Antifrogen SOL HT is premixed with deionized water and formulated
with anti-corrosion additives to ensure optimal frost and corrosion
protection down to -23 °C. It is compatible with standard metal and
plastic components used in solar heating systems.

According to corrosion test method ASTM D1384, the heat transfer
medium protects the metals of solar heating systems against corrosion
and the formation of boiler scale. Trials have shown that under
central European winter conditions the formulation will not cause
bursts in metal system components because slush ice is formed when
the product is cooled below the crystallization point. Antifrogen SOL
HT has a burst resistance of minimum -40°C. It is classified as WGK
1.

In addition to showcasing its offering for the solar heating
market, Clariant reinforces ist commitment to the wider renewable
energy sector by unveiling Antifrogen GEO - ist pioneering new
development for near-surface geothermics - to InterSolar 2010
visitors.

Antifrogen GEO is a heat transfer medium for near-surface
geothermal systems. The clear liquid, tinted green, is suitable for
use at the required application temperatures of -25 °C to +50 °C.

The product's antifreeze action is based on toxicologically
harmless 1,2-propylene glycol. This glycol and the non-toxic
corrosion inhibitors contained in the product comply with the best
possible water contamination classification level (WGK 1).
