Principle: Solarthermic systemsWhy do we need heat transfer fluids ?
Frost protection,
Corrosion protection &
high temperature loads!!

„Captured“ solar energy heats up a
transmitting agent (the heat transfer fluid)
flowing through the solar collector
which is than used eg. for generation of
domestic hot water.
Why do I need Frost protection?

� Efficency of collectors is increasing
maximum temperature loads in collectors:
+250 °C flat collector
+300 °C (and higher) vacuum tube collector
Why do I need a thermal stable heat transfer fluid?

Public: Antifrogen
� Solar systems should generate efficient heat at lower sunshine (spring & autumn)
High loads in summer
� High temperatures can destroy (crack) corrosion inhibitors and the glycol
component of the heat transfer fluid
What can happen, when the HTF is cracked?
� Corrosion inhibitors can be destroyed as well
� Cracking of glycols can lead to the formation of insoluble precipitations

A brown coloration of the fluid shows
overheating of it. But it can be still
usable.
New testing of fluids at high temperatures
� Sealed high temperature test:

When can these overheating precipitations occcur?
� Tests at elevated temperatures (up to 270°C) showed that high boiling glycols are
more resistant to thermal stress than mono propylene glycol.
� Currently nearly all solar heat transfer fluids are based on mono propylene glycol
Achim Stankowiak, Head of Application, Engineering & Aviation (Copyright Clariant. All rights reserved.) Slide 13February 2010

� Based on these results Antifrogen SOL HT was developed with high boiling glycols
as the freezing protecting component.
Which properties have new solar fluids?
� Alternatives to „regular glycol“:

Test results: summary
� Antifrogen SOL HT showed improved thermal resistance in comparison to mono
propylene glycol based heat transfer fluids
� Additionally the results showed that the corrosion additives are stable at elevated
temperatures.
