Description

The Graco Reactor 3 H-50 proportioner is built for serious spray foam professionals handling large-volume commercial or industrial roofing, insulation and OEM applications. With 20 kW heater power and hydraulic direct-drive pump design, the Reactor 3 H-50 offers smooth, quiet operation thanks to elimination of the fly-wheel/belt system. The system features the new touchscreen Advanced Display Module (ADM) that consolidates all spray operations, plus the “Reactor Connect” real-time dashboard capability (via cellular/GPS) for job naming and reporting. Independent hose-heating control allows A and B materials to be managed at different temperatures for optimized yield and pressure balancing. Upgraded inlet filters, fluid manifold and oval-gear flow meters ensure accurate ratio monitoring across viscosities. Both the “Pro” and “Elite” model variations of the Reactor 3 H-50 are rated for up to 2,000 psi (≈140 bar) and roughly 53 lb/min (≈24 kg/min) output. Multiple hose packages (internal vs external heating) and Core pumps are available on the Elite tier, similar to other spray foam professionals rely on for demanding jobs, as well as high-performance systems used in industrial roofing, insulation and OEM applications.

Spray Foam Machine Info & Resources

Technical Specifications

  • Max working pressure: 2,000 psi (14 MPa / 140 bar) for both Pro and Elite H-50 models.
  • Maximum flow rate: 53 lb/min (≈24 kg/min) output.
  • Maximum heated hose support: up to 420 ft (128 m) length.
  • Full system load: 31,700 W (≈31.7 kW) and a primary heater load of 20.4 kW; peak current ~95 A at 200-240 V 3-phase delta.
  • Model variations: H-50 Pro (e.g., part 27R375 for 230 V) and H-50 Elite (part 27R377 for 230 V) — the Elite adds features like electronic pressure control, advanced flow-metering and optional Core E1 transfer pumps.

Frequently Asked Questions

Service & Support

What are the real differences between the “Pro” and “Elite” versions of the Reactor 3 H-50?

The H-50 Pro (e.g., 27R375) and H-50 Elite (e.g., 27R377) share core specs (20 kW heater, 2,000 psi max pressure, 53 lb/min output) but the Elite tier adds enhanced electronic pressure control, better system monitoring (via Reactor Connect), optional Core E1 transfer pumps and advanced hose packages (internally heated, multi-hose options).

Can Reactor 3 H-30 support very long heated hose runs, and does heating type matter?

Yes the Reactor 3 H-50 supports up to 420 ft (≈128 m) of heated hose length. Whether using internally or externally heated hose will affect warm-up speed, weight and flexibility: internally heated hoses warm faster and are lighter.

What electrical supply and cooling requirements does the Reactor 3 H-50 have?

The system has a ~20.4 kW heater load with total system load ~31.7 kW and peak current ~95 A on 200-240 V 3-phase delta. Also the machine uses a hydraulic cooling system for pump oil (powerful fan) to maintain oil temperature and prolong life. Ensure proper three-phase supply, cooling ventilation and power capacity.
