Description

The Graco Reactor 3 E-20 Proportioner gives spray-foam contractors a powerful yet manageable unit designed for smaller-scale jobs or tempered climate use. Available in three tiers—Standard (7 kW heater), Pro (7 kW or 10 kW heater), and Elite (10 kW heater) —the E-20 series supports 2000 psi spray pressure at up to 20 lb/min (9.1 kg/min) output. Advanced features include the Katalyst control system for full system communication, a large touchscreen Advanced Display Module (ADM) for intuitive operation, independent hose-control for A & B materials, and smart supply / auto pressure balance functions that optimise yield and ratio. The design includes a reduced footprint to protect flow-meters and hose connections during transit or rig mounting. With heater options that suit climate and job size, the Reactor 3 E-20 provides flexibility and high performance in a single Proportioner. Model variations: Standard tier with external heated hose (7 kW), Pro tier (7 kW or 10 kW) with internal or external hose, Elite tier (10 kW) with internal heated hose and additional hose-package options (E1 Core Pumps required for Katalyst). For higher-output spray-foam applications, larger systems are also available.

Frequently Asked Questions

Service & Support

What are the real job-site limitations when using the Standard (7 kW) tier of the Reactor 3 E-20 compared to the Elite (10 kW) tier?

While the Reactor 3 E-20 Standard tier can hit the same maximum flow rate (20 lb/min) and pressure (2000 psi), the lower heater wattage means slower warm-up and less head-room when spraying high-viscosity materials or working in very cold conditions.

Can I upgrade a Pro tier unit (7 kW) to the 10 kW heater later, and what cost/implication is there?

Upgrading your heater can be costly, talk with a Polysource rep to help find the best solution.

How does the choice between internal-heated hose vs external-heated hose affect job-site setup and performance on the Reactor 3 E-20?

Internal-heated hoses maintain fluid temperature throughout the hose via embedded heating elements, reducing temperature drop over hose length and enabling longer runs or colder environment use. The Elite tier uses these. External-heated hose packages wrap heaters around the hose and may be more prone to heat loss or require more insulation, but are generally less expensive and fine for shorter hose runs or moderate climates. The Reactor 3 E-20 Standard and Pro tiers offer external heated hose packages (or internal in Pro) depending on configuration.
