The main purpose of the vacuum deaerator is to release the dissolved gases circulating in closed-circuit heating and cooling systems and to discharge them from the system.
ViraDeg vacuum degasser is connected to the system as a by-pass and after pressurizing the water it has taken from the system, it applies a vacuum, allowing dissolved gases to be released in the water. The released gases are discharged from the system using airvents.
Vacuum degassing is the technique of removing dissolved gas from a liquid solution by lowering the pressure inside a vessel containing the solution. Vacuum degassing is the process of removing dissolved gas from a liquid solution by lowering the pressure inside a vessel containing the solution. The reduced pressure inside the vessel causes the gas to become less soluble and separate from the liquefied material. After vacuum degassing is complete, the gas is removed from the vessel and the pressure returns to normal.
