In this video, Bill Bailey, discusses the importance of air elimination in hydronic systems.
Facility managers and engineers want to eliminate air from hydronic systems to prevent noise and corrosion. Air bubbles circulating in the system can cause disturbances by impinging on metal components, creating unwanted noise. Additionally, the oxygen in the air can be corrosive, leading to the formation of rust and other undesirable byproducts.
Bailey covers different methods of air elimination, including the basic air vent, the air scoop, the roll air troll, and the air eliminator.
Air eliminators are the most modern and effective form of active air elimination. The air Eliminator, always in contact with the circulating water, captures air bubbles using a cage mechanism. The air bubbles rise to a float, triggering the elimination process.
These air eliminators are designed to be self-maintaining, with some models allowing for the removal and cleaning of internal components without shutting down the system.
