EXCELOT integrates advanced technologies like EvapCare™ evaporators, OptimEXTTM extractors, and Mellapak™ packings, allowing our customers to separate azeotropes, heat-sensitive materials, and mixtures with limited vapor-liquid equilibrium data. Together with the tailored design concepts and workflows, we fulfill those separation tasks with minimal product losses.
With over 30 modular units started up and commissioned worldwide, EXCELOT has established strong references in:
-
Solvent recovery (e.g. ethanol, isopropyl alcohol, MEK, acetates, acetonitrile, DMA, hexadiene and more)
-
Multipurpose distillation (up to 20 waste streams or feedstocks)
-
Purification and fractionation of heat sensitive products (e.g. essential oils, limonene, menthol, eucalyptus, lavender, tea tree and API)
Extraction of vitamins, nutraceuticals and essential oils.
-
EXCELOT’s modular design allows for swift installation and commissioning. Order-to-dispatch time can be as short as 9 months. Depending on our customer needs, the unit is tailored to fulfill space limitations (especially height).
