Vacuum degasser is also known as: Vacuum Jet Exhauster, Vacuum Exhauster, Vacuum Degassing Tank, Vacuum Degassing Unit, Vacuum Degassing Unit, Vacuum Splash Exhauster and so on. Heating and cooling system if there is gas, the system is prone to gas resistance, resulting in local or the entire system of poor circulation, water resistance increases resulting in the heating system is not hot, the refrigeration system is not cold. At the same time as the water contains oxygen and make the heating (refrigeration) equipment, piping and steel radiators have oxygen corrosion, resulting in perforation, water leakage. Gas in the system will also cause corrosion of the pump, directly affecting the safety of the entire system. Vacuum degasser using vacuum degassing method, quickly remove the free gas and dissolved gases in the system, so that the system can operate safely and reliably. In the circulating water system, many users will be water softener, fixed-pressure water replenishment device, spiral decontaminator and vacuum degasser used in conjunction with both to reduce scaling, so that the system pressure is stable, reduce energy consumption; but also slow down the corrosion, reduce the noise, reduce the turbidity of the water.

Vacuum degasser is a new generation of degassing device for circulating water system. Effectively solve a series of problems due to the heating and cooling system, due to the existence of gas caused by the local or the whole system circulation is not smooth air resistance phenomenon, the system contains oxygen caused by the noise in the pipe network, heat exchanger heat transfer effect is poor. Vacuum degasser is an important and indispensable part of circulating water system.
Vacuum degasser is widely used in HVAC circulating water system, can effectively remove the free state of water and dissolved state of air and oxygen, degassing efficiency is greater than 99%, so as to completely solve the problem of pipeline air resistance and air blockage, eliminate the noise of the pipeline network system, greatly reduce the oxygen corrosion of the radiators and pipelines to eliminate the pump erosion, prolonging the service life.

Vacuum degasser working principle:

Vacuum degasser according to Henry's law, the solubility of gas in water is related to water temperature and pressure. At a certain temperature, it is directly proportional to the pressure of the gas. At a certain pressure, the solubility of the gas increases when the water temperature is lowered and the solubility of the gas decreases when the water temperature is raised. When the pressure on the water surface is reduced, the gas dissolved in the water can be precipitated at a lower water temperature, thus removing the gas from the water. Vacuum degasser is to release the free and dissolved gases in the water by generating a vacuum, then discharge the system through an automatic exhaust valve, and inject the degassed water back into the system. This low gas content water is unsaturated water, which is highly absorbent to gases, and it will absorb the gases in the system so as to achieve gas water balance. The vacuum degasser repeats this cycle every 20-30 seconds. This cycle is repeated to remove most of the gas from the system.

Vacuum degasser function:

Vacuum degasser can remove the gas in the make-up water and circulating water system, so as to protect the safe and stable operation of the equipment and system. Analyzing gas - analyzing free gas and dissolved gas in the system.

Vacuum degasser technical characteristics
1, can greatly shorten the heating or cooling system after the initial injection of water exhaust time, very conducive to the initial commissioning of the system operation.
2、Vacuum degasser can remove the gas in the system, greatly reduce the gas resistance, reduce energy consumption, to ensure the stability and reliability of the system during operation.
3、Eliminate pump cavitation, reduce system operation noise.
4、Vacuum degasser working time and cycle can be adjusted according to the need.
5、Single applicable system capacity up to 150m3, can be used in parallel.
6、With terminal, with remote control function.
7、Vacuum degasser is suitable for any heating or refrigeration system to improve the performance of heat exchanger.
8、Because the equipment is vacuum degassing deoxygenation, there is no secondary pollution.
9, the vacuum degasser can greatly reduce the pipe network, radiator, pumps and other equipment, oxygen corrosion, can extend the service life of the system.
10、When the system is running normally, it can uninterruptedly discharge the air brought about by the leakage of pipe network and water replenishment of the system to maintain the stable operation of the system.
11、Vacuum degasser can eliminate the tiny air bubbles attached to the surface of the heat transfer equipment, improve the efficiency of heat transfer.
12、Vacuum degasser is small in size, space-saving, easy and convenient to install, flexible installation position, easy to repair and maintenance, fully automatic operation, safe and reliable.
