Diesel Spray Foam Rig Cost

Diesel spray foam rigs provide more consistent power delivery under sustained production load than gas platforms. They typically use hydraulic or electric proportioners with higher heater wattage packages and diesel generators.

• A professionally engineered solid-state diesel spray foam rig includes:
• Graco Reactor 2 or equivalent hydraulic or electric proportioner
• 30 kW+ diesel generator
• Refrigerated air dryer
• 210+ ft heated hose system (with option for longer extensions)
• Complete safety package
• Training

A well-configured diesel rig from a credible dealer runs $95,000–$130,000 depending on machine selection and options.

• What drives diesel rig cost above a gas rig:
• Diesel generators cost more than equivalent gas generators
• Hydraulic proportioners cost more than air-driven machines
• Higher heater wattage packages on diesel machines drive generator sizing up
• Diesel rigs are often configured with longer hose systems

The diesel cost premium is justified by more consistent production performance — particularly in cold weather, on long hose runs, and during continuous sustained production.
