Function
Air separators are used to continuously remove the air contained
in the hydronic circuits of heating and cooling systems. The air
discharge capacity of these devices is very high. They are capable
of removing automatically all the air present in the system down to
micro-bubble level.
The circulation of fully de-aerated water enables the equipment to
operate under optimum conditions, free from any noise, corrosion,
localized overheating or mechanical damage. Micro-bubbles, fusing
with each other, increase in volume (get larger) until they become
large enough to rise to the top where they are automatically
released.
