International classifications

DIN 51522 class Q - ISO 6743-12 L-QD - Oil

Excellent stability to thermal cracking.
Authorizes lengthy periods without the formation of carbon deposits which can foul the circuit. Preserves the heat exchange characteristics of the installation.
Resistance to oxidation.
A thermal fluid must show good resistance to oxidation, even with limited exposure to oxygen in the air. JARYTHERM DBT offers this characteristics.
