How to Combat Iron Oxide in Hydronic HVAC Systems

Posted by Kelly Patterson on Feb 7, 2019 2:07:02 PM

Air in a hydronic HVAC system can be a problem, specifically when it comes to the development of corrosive iron oxide.  When system components, like pump volutes or expansion tanks, made of cast iron or steel are mixed with oxygen and water, corrosive iron oxide is formed.  Commonly known as "black sludge," iron oxide includes magnetite.  Magnetite is a naturally occurring brownish-black or black material that is extremely fine and becomes a black, sticky mess inside hydronic systems.  Magnetite can get into valves and ECM motors.  It can also build up on the surfaces in a boiler or heat exchanger and act as an insulator to reduce heat transfer and system efficiency.

Does Your System Need Shaft Grounding Technology?

Posted by Kelly Patterson on Nov 16, 2018 9:40:40 AM

We are huge advocates of utilizing VFDs to control AC motors in most instances.  It isn't often that we need to run a pump motor at full speed, so we can reduce our energy consumption (lower costs) while being a little kinder to our motors by installing VFDs in our systems.  Rarely in life do we encounter anything that is flawless, however, and VFDs are no exception.  They do lower our operating costs and can increase system performance, but they also create shaft voltage.
