When a new high-rise hospital and medical research laboratory facility was being built, design engineers sought a piping system that would maintain and deliver high-purity water. To accomplish this they needed constant water movement to eliminate any areas where still water could stagnate. Stagnate water is one cause of bacterial and other organic growth.
Design engineers chose to install the AquaTap™ recirculating faucets manufactured by GF Piping Systems along with the company’s in-line flow diverters to deliver high-purity water to multiple points. The recirculating faucets keep the water in constant motion, preventing stagnation. The faucets also eliminate the need for extensive water purging by providing continuous flow through the faucet head and preventing the formation of harmful bacteria. In-line Flow Diverters (IFD), which are part of the faucet package, are designed to deliver just the right amount of water to each faucet with minimal pressure drop across the main UPW loop. In this facility, over 30 faucets were installed that recirculate an average of 70 GPM of DI water daily.
“Other faucet systems on the market have sections of pipe, such as underneath a sink, where waterbecomes stagnant, resulting in reducedwater quality,” points out Terence Zhao, Product Manager of Engineered Piping Systems for GF Piping Systems. “This was a key point in their decision on the Aquatap.”
