Maintaining the health of water circulating within hydronic and plumbing systems is vitally important for optimal performance. The ideal fluid within these systems would have no impurities, air bubbles or dissolved gasses. But have you experienced such symptoms as insufficient flow, pump air lock, low temperature, noise, low heat transfer or corrosion? These are telltale signs of excessive air contained in a system. Bob “Hot Rod” Rohr, Caleffi training and education manager, will discuss how air enters a system, common air related symptoms and discuss venting solutions for successful air removal.
→ The system is closed, how does air even get inside?
→ What are the most common symptoms of air inside a system?
→ What devices are used for air removal? How are they designed?
→ Can another system component mask an air problem?
→ What goes on inside an automatic air vent?
→ What is the effect of hydrostatic head? Of pump placement and orientation? → What’s unique about DHW recirculation applications?
→ What causes air vents to be changed out needlessly?
