The Mikrofill 3 hydronic system pressurization unit is the most advanced, “direct-type” pressurization unit available for sealed, low-pressure hot-water (LPHW) and chilled-water (CHW) commercial and multifamily residential applications, the company says.
Watts announces the addition of the ArmorTek advanced coating system to its ductile-iron backflow preventer valves. This advanced patent-pending technology provides three layers of protection to create an effective barrier, dramatically increasing resistance to corrosion, Watts explains. ArmorTek provides an advanced primer, which contains an electrochemical corrosion inhibitor. It significantly slows the spread of corrosion should the metal substrate become exposed from wear or impact. ArmorTek’s exclusive formulation also inhibits the growth of bacteria that cause microbial-induced corrosion or MIC.
