Boiler Feed Water Deaerators and Corrosion Control
Many plants are now using Liqui-Cel® Contactors for the deoxygenation of their boiler feedwater. Boiler deaeration extends boiler and piping life by preventing corrosion of critical parts. Liqui-Cel® Contactors facilitate boiler deaeration and corrosion control.
Flexibility in Semiconductor Applications
In the semiconductor and flat panel/TFT industries, high levels of oxygen can cause lower wafer and flat panel yields. Liqui-Cel® Contactors are the degassing standard in the microelectronics sector where the dissolved oxygen specification is critical. Our contactors can produce <1ppb of dissolved oxygen and carry a performance warranty. We have thousands of systems operating around the world today.
Beverage and Food Processing Applications
Liqui-Cel® Membrane Contactors are used around the world for the deoxygenation of water, beer and other liquids in the food and beverage industry. Oxygen can negatively impact the shelf life, product quality, product consistency and taste. Liqui-Cel® Contactors offer a small, modular, and cost effective means to control the dissolved gasses in the beverage. Beer, wine and juice processing are common applications for our membrane deaerators.
