Being the most traditional representative of mass transfer equipment, the bubble cap tray is still today indispensable for applications with very low vapor or liquid loads, or wide variations of the flow rates. The liquid tight risers and the flow of the vapor stream through the submerged slots in the bubble caps ensure a permanent contacting between both phases. Using sealed constructions, very low leakage rates can be achieved.
Various shapes, sizes and types of design allow tailor-made solutions for your individual needs. Bubble cap trays can be manufactured from metallic as well as from thermoplastic materials.
