Deaeration and de-gassing Equipment is typically used to remove atmospheric gases from liquids, such as oxygen and carbon dioxide. Probably the most common application is the deaeration of water to reduce the oxygen content. The presence of oxygen in water can reduce shelf-life and storage performance of many beverages, food and liquid products and their ingredients. It increases the risk of microbiological activity. The presence of both O2 and CO2 in boiler feed water accelerates costly corrosion in heating systems and boiler heat exchangers.
Centec provide a range of different deaeration technologies, the selection of which varies according to the application and project requirements. Centec custom design and build deaerators to suit the needs of each client and their specific duties.

DGS - Hollow-Fibre Membrane Deaeration Technology:
Principle: Water is passed through a chamber containing a very large number of extremely small bore tubes which are manufactured in a gas porous, hydrophobic, FDA conforming plastic. A sweep gas under vacuum passes through the small tubes counter-current to the water. Gases such as Oxygen, Carbon Dioxide, Nitrogen and even Hydrogen pass from the water into the small tubes via microscopic pores. This ‘state of the art’ technology is highly effective and complies to the strict material and quality requirements of the bio-pharmaceutical industry.
Capacity: 1 to 200 m3/h (10 to 2000 hl/h), custom capacities on request
Residual O2: <0.005 ppb
Operating temp.: +2 to 45°C (CIP up to 85°C)
Applications: Beverage, Pharmaceutical, Inks, Boiler Feed, Semi-Conductor Wafer,
Residual O2: <0.005 ppb
Operating temp.: +2 to 45°C (CIP up to 85°C)
Applications: Beverage, Pharmaceutical, Inks, Boiler Feed, Semi-Conductor Wafer,
Principle: Water passes counter-current down through a vertical column of stainless steel distributive packing to optimise the surface area. CO2 or N2 gas flowing in the opposite direction causes the oxygen to come out of solution. DeGaS systems are operated with both cold and hot water. For best O2 removal performance, Centec systems can pre-heat the water. A cost effective and reliable solution, to suit specific application requirements.
Capacity: 5 - 150 m3/h (50 - 1500 hl/h)
Residual O2: <10 ppb (custom designed to meet URS)
Operating temp.: +9°C to 72°C (95°C for CIP)
VeGaS - Vacuum Deaeration:
Residual O2: <10 ppb (custom designed to meet URS)
Operating temp.: +9°C to 72°C (95°C for CIP)
VeGaS - Vacuum Deaeration:
Principle: A traditional method. Water is sprayed into a vacuum chamber. The level of vacuum is adjusted based on the required oxygen content, temperature and product characteristics. The deaerated water falls to the bottom of the chamber from where it is pumped away.
Capacity: 5 - 150 m3/h (50 - 1500 hl/h)
Residual O2: <10 ppb (custom designed to meet URS)
Operating temp.: +9°C to 72°C (95°C for CIP)
Residual O2: <10 ppb (custom designed to meet URS)
Operating temp.: +9°C to 72°C (95°C for CIP)
