Melt crystallization for high purity chemical products
Achieve ultra-pure products with minimal energy by integrating melt crystallization into your process, perfect for separating closely related compounds without solvents.
Crystallizes and Purifies High-Purity Compounds
The Melt Crystallizers from GEA are designed for industries demanding high-purity results, such as pharmaceuticals and fine chemicals. Utilizing a suspension-based crystallization system, it concentrates impurities in the mother liquor while ensuring crystal purity. Suitable for applications from catalyst material purification to solvent-free aroma extraction, it operates continuously with low energy consumption, reducing heat requirement by up to four times compared to traditional methods. Featuring integration-ready automation, these crystallizers offer stainless steel construction for enhanced chemical resistance. They seamlessly fit into your processing line, allowing easy debottlenecking of existing distillation processes to increase capacity by 25%. Incorporating advanced wash columns, they guarantee superior purity by effectively removing residual mother liquor. GEA also provides engineering support for customization, ensuring the equipment meets your specific processing needs.
