Which glycols are compatible with SPRING4 panels?

Edited

DualSun SPRING4 panels are compatible with many glycols.

In order to have good protection against frost we recommend using a coolant with the following characteristics :

ready to use:already mixed with the correct concentration of glycol depending on the geographic area of the installation
Effect anti corrosion
glycol with the lowest possible viscosity in negative temperatures

Here are the glycol references already validated with the aluminum exchanger of the SPRING4 panel:

Antifrogen® SOL HT (Clariant International Ltd)
Coracon Sol 5 et Coracon Sol 5F (Aqua Concept GmbH)
®PEKASOLar 30-50% (per KÜHLSOLE GmbH)
Solarliquid L (Staub & Co Chemiehandels GmbH)
Tyfocor® L (Tyforop GmbH)
