To prevent damage to the collectors and their connections by frost
and corrosion, it is essential that a high quality heat transporting fluid
be used to fill the solar installation. Use of the heat transporting fluid
that we propose provides good anti-frost protection down to
approximately -24°C.
To prevent any damage of the system,
pressure tests
should only
be carried out with the
heat-transporting fluid
used later on.
