3.1 Product overview

The CRS removes free and entrained air and separates dirt, sediment, and unwanted
material from the hydronic system.
The CRS has the following optional accessories:
• Air vent
• Blowdown valve
• Skim valve
Stainless steel media construction provides durability and long life.
A magnetic separation option is available to remove the black iron oxide (magnetite)
suspended in the water. Iron oxide can collect inside pumps, boilers, heat exchangers, and
other system components, resulting in substantial loss of system efficiency and possible
damage to those components. The separator consists of an innovative magnetic insert
assembly, containing multiple high-performing neodymium magnets.
The design and construction of this separator conforms to ASME Section VIII, Div.1. This
product is intended for hot and chilled water systems.
WARNING:
This product can expose you to chemicals including Lead, which is known to the State of
California to cause cancer and birth defects or other reproductive harm. For more
