BrassMaster Boiler Fill Softener

BrassMaster Boiler Fill Softeners provide a portable, economical means for plumbers and HVAC technicians to supply a softened, scale-free initial fill of water to residential and commercial hydronic systems. Simply connect hoses to the inlet and outlet ports. Mix the now softened water with glycol (as needed), and pump into the HVAC system.

Hardness, often comprised of calcium and magnesium (along with iron), is commonly found in both public and private water systems. Left untreated, these minerals can cause scaling, decrease efficiencies, and create significant maintenance burdens in HVAC systems.

BrassMaster Boiler Fill softeners are portable, lightweight systems that use the process of “ion exchange” to effectively remove these undesirable minerals. The result is a cleaner system fill with less headaches for operators.
