In thePrinting & Dyeingindustry, precise thermal control is essential for shade consistency, fabric handle, dimensional stability, drying efficiency, and continuous finishing reliability. Modern stenter and finishing lines are widely used to dry, set, and stabilize dyed or printed fabrics, with textile drying commonly performed around150–160°C, while heat-setting of blended and synthetic fabrics can reach up to220°C. Studies also show that controlled pre-heating at100–105°Ccan increase stenter productivity by approximately17% to 30%, reduce dwell time, lower electricity consumption, and help prevent fiber damage caused by thermal shock. Within this demanding operating window,Eurotherm 320provides a dependable-30 to 320°Crange with9.8 mm²/s viscosity at 40°C, combining low-viscosity circulation, strong thermal stability, and high 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, making it ideal for fast start-up, rapid circulation, and flexible process changeovers. For larger closed-loop systems,RÜTGERS Ruetaflex 1000offers-55 to 330°Ccoverage with6 mm²/s viscosity at 40°C, low-pour-point fluidity, and long service life, helping printing and dyeing plants reduce maintenance, stabilize continuous operation, and deliver more consistent fabric quality.
