What is Glykosol N?
Product Description
GLYKOSOL N is a yellowish liquid based on monoethylene glycol for use as a heat transfer medium with highly effective corrosion protection additives and hardness stabilizers. GLYKOSOL N is free of nitrite, amine and phosphate.
GLYKOSOL N is used as an antifreeze and corrosion protection medium in all technical areas, e.g. for heat pumps, ground probes, air conditioning systems, heat recovery systems, heating and cooling systems.
The inhibitor system protects all commonly used metallic materials, reliably against corrosion and deposits (tested according to ASTM D 1384-96 by the Institute for Materials Research for air and refrigeration technology, Dresden).

Use of GLYKOSOL N
Instructions for use
GLYKOSOL N can be mixed with water in any ratio. The concentration should not fall below 20 % by volume, as corrosion protection is no longer guaranteed.
GLYKOSOL N should only be diluted with water up to a hardness of 20°dH. Ideally, demineralised water should be used.
Recommendation Application concentration
For the following applications we recommend the following concentrations:
| Application | Concentration |
|---|---|
| Heat pumps and geothermal probes | 25 - 35 Vol.% |
| Air conditioning systems and heat recovery systems | 35 - 40 Vol.% |
| For pure frost protection | 35 - 40 Vol.% |
