The Mono-Block III is the latest generation of the Mono-Block series of additive injectors, the industry's most widely used injector design. Its compact solid stainless steel block integrates an oval gear meter, explosion-proof solenoid and Ex-certified Hall-effect sensor, strainer basket and ball check valve. It is offered in standard-flow and low-flow models and works with Fusion4 MSC-A and SSC-A smart injector controllers, loading presets and terminal automation systems for accurate treat-rate control of fuel additives.
