In the Hazardous Waste Treatment industry, precise thermal control is essential for safe containment, efficient recovery, and stable continuous operation. From waste-solvent recovery and distillation to evaporators, reactors, and indirectly heated thermal-treatment systems, operators depend on heat transfer fluids that deliver uniform temperature profiles, limit hot spots, and support process reliability in aggressive service environments. Chemie positions its thermal fluids as part of a broader industrial portfolio supporting circular-economy applications, including hazardous waste treatment, where consistent indirect heating can improve recovery efficiency and reduce downtime. EuroTherm 320 (E320) provides -30 to 320°C service with 9.8 mm²/s viscosity at 40°C, combining low-viscosity circulation, strong thermal stability, and cost-effectiveness for standard treatment loops. EuroTherm 330 (E330) offers -49 to 315°C operation,4.04 mm²/s viscosity at 40°C, and a-68°C pour point for rapid start-up and responsive control.EuroTherm THT (THT)extends performance to-10 to 350°Cwith28 mm²/s viscosity at 40°C, low system pressure, and excellent high-temperature stability.RÜTGERS Ruetaflex 1000 (R1000) delivers-55 to 330°Cservice with6 mm²/s viscosity at 40°C, while RÜTGERS Ruetasolv BP-D (BPD) reaches -55 to 350°Cwith alow-pour-point, low-viscosity profile and exceptional thermal stability, helping hazardous-waste facilities improve process control, operational safety, and long-term reliability.
