  Felder Lottechnik coolant 1lt purchase 9 packs x 3.50€ liquid color blue.
  The cap (with a little effort) unscrews without the plastic safety ring of the packaging being detached.
  With a composition of propylene glycol (clear liquid, thick and sticky texture), I opened 4 packs, all incomplete, ranging from 915ml to 925ml, they do not have a thick texture like the previous pink antifreezes I had, but watery, they are already diluted, unknown with what and in what percentages are not mentioned.
  I mixed 1 liter with 1 liter of deionized water from the market, I did not have rainwater or air conditioning, measurement indication -22°C.
  I used it for solar and antifreeze purposes and they perform as they should.
  I have reservations and doubts about the product, however, there is no mention as an image on the specific Felder Frostschutzflüssigkeit (Felder frost protection liquid) in the Google search engine.
  The brand Felder Lottechnik represents products of cold and hot industrial bonding.

  German Quality, top coolant for closed circuits, I have been using it for years in solar water heaters. Top choice for closed circuit solar water heaters!

  I have noticed that whenever I have used it in heating installations, after a year, all the cables started to lose. In solar ones, I had no problem.
