Graco

At the heart of professional spray foam insulation lies Graco’s precision-engineered Reactor equipment line. Designed for the demands of residential, commercial and industrial insulation jobs, Graco proportioners deliver consistent on-ratio performance with advanced ratio assurance technology. Built for reliability, Reactor systems help insulation professionals spray with confidence on every project.

Graco’s Reactor^® 3 proportioners set the standard for spray foam insulation performance through a proven combination of durability, control and intelligent ratio monitoring. The multi-tiered Ratio Assurance System continuously detects and prevents off-ratio conditions. Katalyst^™ software provides drum-to-gun communication and control that improves performance, ratio and yield. Mechanically linked, positive displacement pumps provide consistent volumetric output, and with Auto Pressure Balance the Reactor automatically adjusts temperatures to optimize fluid pressures and maximize material yield.

 

Available in air, electric and hydraulic configurations, Reactor models are tailored for every insulation need – from residential retrofits to large commercial and roofing applications. Built in the United States with global components, each Reactor system is engineered for long-term reliability and precision, helping contractors reduce rework, minimize waste and achieve high-quality, energy-efficient results.
