Neglecting the benefits of Sulzer coolers and static mixers in fiber plants may cause various melt qualities at all spinneret blocks and therefore a significant down time due to fiber breakage.

The Sulzer SMR® Cooler is used to efficiently cool down the polymer melt. The Sulzer SMX® mixer is used to achieve high homogeneity after admixing additives. The so called 2D and 3D modules are a tool to fully homogenize the melt before each flow split.
