Principle: Solarthermic systemsWhy do we need heat transfer fluids ?

Frost protection,

Corrosion protection &

high temperature loads!!


Public: Antifrogen

„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


Public: Antifrogen

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:


Public: Antifrogen

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


Public: Antifrogen

� 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
