Harrier Chemical Injection Controllers

Harrier Electronic Chemical Injection Controllers

For controlling and monitoring automated injection systems

Chemical Injection Controllers are used to monitor, meter and control the amount of chemical being consumed in a system.

Closely control and monitor chemical critical operating information for reducing costs and improving processes. It’s easy, efficient and productive – saving you time and money.

  • Simple user interface for setup and control. Enter your desired injection rate and let Graco do the rest.
  • The Harrier+ control includes remote connectivity, allowing you to monitor, control and calibrate your system away from your injection site via cellular or ModBus.
  • Easily monitors your system for control, troubleshooting, maintenance needs and alerts.
  • Patent pending adaptive flow control technology maintains a consistent injection rate, regardless of system variables, reducing waste and costs.
  • Multiple inputs for system controls allow you to only run when it’s necessary.
