Columns are designed for heat-exchanging and mass-transfer processes. Columns are basic processing elements for absorption, desorption, rectification, cooling, humidifying and purification of gases. We produce both section-welded and all-welded columns, dia. 400 - 8000 mm, max. weight 600 tons, equipped with various internals. Column internal parts
