Technical Description
Description The DLR Series is designed with a single low-pressure high-intensity UV lamp centered
inside a protective quartz sleeve. The disinfection chamber is either 304 or 316L stainless
steel and is electro-polished with male NPT Inlet/Outlet. The UV lamp and quartz jacket
assembly are easily removable from one side of the disinfection chamber.
