Engineered for versatility, the Graco HFR Metering System packs advanced technologies and precision dispensing into one compact, affordable system.

The Graco HFR Metering System is one of the first modular, configurable systems in the polyurethane processing equipment marketplace. While other systems are custom designed for specific applications, the Graco HFR Metering System is modular and offers more technology for a lower capital investment than traditional custom RIM equipment.
