Tarmond Thermo Series are high-performance heat transfer oils designed for use in closed-loop and circulating systems, operating at temperatures up to 315 °C. They provide excellent oxidation resistance and thermal stability, ensuring efficient heat transfer. The oils are resistant to thermal cracking, leading to minimal residue formation. They maintain good fluidity at low temperatures. Recommended for reactors, distillation and polymerization systems, dryers, heat exchangers, and other industrial heat recovery processes.
Meets the Specifications: ISO 6743-12 Q; DIN 51522
Please check your owner’s manual for the manufacturer’s recommended oil viscosity grade and API classification and approvals.
