Vacuum Degassers
A fully automatic vacuum degasser for the removal of dissolved gases from closed-loop water systems. This helps eliminate potential for corrosion to occur.
The presence of air in an HVAC system contributes to premature rusting and the deterioration of metals throughout a piping network.
Removing air when it’s in a dissolved, gaseous state is akin to tackling a problem at its source.
Our vacuum degassers achieve this by:
- Taking water from the system
- Delivering it into a vessel
- Returning the degassed liquid to the system
- Lowering the pressure causes the gas to become less soluble and separates it from the liquid
Features
If your unit requires a working pressure of more than 900kPa, our team can design a bespoke system to suit a high-pressure application.
Options include:
- V4 – 4bar
- V6 – 6bar
- V9 – 9bar
The unit is suitable for use in systems filled with clean water or mixtures of water with maximum of 40% glycol. Use in combination with other fluids may result in irreparable damage.
A unit with a refill function can control the pressure of the installation. To control the pressure, the unit inserts additional degassed fluid into the installation, if necessary. The unit can also fill the entire installation with degassed fluid.
The unit starts up a degassing process each day at a time set by the user.
The process has two phases:
- The rinsing phase (the fluid flows from the installation through the solenoid valve (S) into the vessel. The pump continuously pumps the fluid from the vessel into the installation. Here the fluid absorbs gases present in the installation.)
- The vacuum phase (the solenoid valve (S) regularly closes, starting a vacuum phase. The continuously running pump provides under pressure in the vessel. The under pressure causes the release of the gases dissolved in the fluid, which are collected at the top of the vessel. The gases are removed from the installation through the automatic air vent. The SmartSwich at the automatic air vent makes sure that the stopped as soon as the content of dissolved gases has reached the minimum level. The solenoid valve (S) opens again, at the end of the vacuum phase.)
Frequently asked Questions
- What is the difference between an air separator and a vacuum degasser?
The Optivent Vacuum Degasser releases dissolved gasses in water, but an Optivent Air Separator releases microbubbles and free air in the system. These are different solutions.
- If I have an air separator, do I still require a vacuum degasser?
Yes. A vacuum degasser provides a solution against corrosion and extra air.
