Packed tower internals
The proper selection and design of packed tower distributors, collectors, supports, and other column internals are essential for optimum packing performance. At Koch-Glitsch we take special care to assure that liquid and vapor distribution to the packed bed is uniform and that the equipment is selected to best handle any special process considerations, such as fouling or foaming. We offer a proven line of distributors and redistributors for a wide range of flow rates, physical properties, and turndown requirements. Our internals are available in a variety of styles and materials, including ceramic, graphite, and many plastics.
