DuPont™ Ligasep™ Degasification technology

Reliably and Sustainably producing industrial water

Introduction Cutting-edge in design, but simple in operation

When industrial equipment is in contact with water used Ligasep modules feature a radial flow design that more effectively in a process or as an ingredient, oxygen and carbon dioxide removes gases and have our advanced skinned membranes in that water cause corrosion. at the core. This next-generation approach prevents seepage Degassing this water is essential, and our Ligasep system does of water vapor across the membrane, removing the necessity so precisely and highly autonomously. for a more expensive water-sealed vacuum pump and reducing the risk of failure. As it generates a deeper vacuum, no additional Compared to large and high-maintenance conventional systems, nitrogen is required to further dissolve the oxygen, saving on

Ligasep uses advanced membrane technology to take out all the production of N2 and other scavengers. question marks – consuming less energy and chemicals to give industrial producers a precisely engineered, smaller and cost-effective Ligasep is highly flexible, low on OPEX and capable of fast solution that extends their equipment service life and increases start-ups and seamless adaptation to fluctuating flows. process uptime. Easy to maintain, the system is highly automated so you will not need on-site expertise to supervise it. Should the need arise, our technicians are soon on-site to give it a service.
