Chemical Injectors
KENCO Chemical Injectors are designed to inject and properly atomize corrosive chemicals into the turbulent stream of a process system pipeline. The KENCO Chemical Injector will minimize the possibility of corrosive chemical build-up on the walls of the pipeline. KENCO Chemical Injectors are recommended for use in pipelines with a flow-rate velocity of 40 feet per second (12.192 meters per second), or less.
