In theTextilesindustry, precise thermal control is essential for fabric drying, heat-setting, dimensional stability, and continuous finishing efficiency. Modern stenter lines are widely used not only for drying but also for heat-setting, with textile drying commonly performed around150–160°Cand heat-setting of blended or synthetic fabrics reaching up to220°C. Studies also show that controlled pre-heating at100–105°Ccan raise stenter productivity by approximately17% to 30%, while reducing dwell time, lowering annual electricity use, and helping prevent fiber damage caused by heat shock. In this demanding operating window,Eurotherm 315offers-25 to 315°Cservice with15.62–19.70 mm²/s viscosity at 40°C, a-54°C pour point, and stronger oxidation stability than mineral-based oils, making it a durable upgrade for traditional textile heating systems.Eurotherm 320provides a dependable-30 to 320°Crange with9.8 mm²/s viscosity at 40°C, combining low-viscosity circulation, thermal stability, and cost-effectiveness for mainstream drying and finishing duty.Eurotherm 330extends low-temperature flexibility with-49 to 315°Cservice,4.04 mm²/s viscosity at 40°C, and a-68°C pour point, ideal for fast start-up and flexible changeovers. For larger closed-loop systems,RÜTGERS Ruetaflex 1000delivers-55 to 330°Ccoverage with6 mm²/s viscosity at 40°C, low-pour-point fluidity, and long service life, helping textile plants maintain stable heat transfer, reduce maintenance, and improve continuous production reliability.
