Vacuum Degassers

A fully automatic vacuum degasser for the removal of dissolved gasses from closed loop water systems.

Economical, reliable and convenient

The presence of air in a HVAC water system contributes to premature rusting and deterioration of metals throughout a piping network. By removing air when it is in a dissolved gaseous state is akin to tackling a problem at its source. In summary the Masterflow Vacuum Deaerators achieve this by:

  1. Taking water from the system into delivering into a vessel
  2. Lowering the pressure causing the gas to become less soluble and separating from the liquid.
  3. Once this is complete, the degassed liquid is returned to the system.

Why A Vacuum Degassers

Features

  • Refill functionality available as an option. This will contribute to automatic makeup of the system should there be any minor losses or leaks within the piping network.
  • The unit operates until the entire system has been degassed. It will then switch off until new water or a leakage is detected and the need to degas returns.

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.

The unit starts up a degassing process each day at a time set by the user. The process has two phases:

  1. 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.
  2. 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.

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.

Frequently asked Questions

The Optivent Vacuum Degasser releases dissolved gasses in water but an Optivent Air Separator release microbubbles and free air in the system. These are different solutions.

Yes. A Vacuum Degasser provides solution against corrosion and non extra air inlet when system need refilling.
