Diesel Rig Production Capabilities

Diesel spray foam rigs are designed for higher production volumes, longer hose runs, and more demanding environmental conditions than typical gas rig configurations.

Output rates: Diesel rigs typically use electric or hydraulic proportioners with output rates in the 20–50 lb/min range depending on machine configuration. The Graco Reactor 2 H-30/H-50 and PMC Premiere/Mach-2 platforms are common diesel rig machines.

Hose capability: Standard diesel rig configurations support 210 ft of heated hose as a base configuration, with extension packages supporting 300–420 ft depending on machine and heater wattage.

Cold weather performance: Higher heater wattage (12–18 kW) combined with stable diesel generator output allows diesel rigs to maintain material temperature on long hose runs in colder ambient conditions where gas rigs may struggle.

Sustained production: Diesel engines are designed for continuous load operation. A diesel generator running at 70–80% load is operating in its design range. Gas generators running at sustained high load experience more wear and are more prone to performance degradation over a full production day.

Multi-application capability: Diesel rigs with higher output machines support multi-gun operations, slab jacking systems, and polyurea applications — capabilities that standard gas rig platforms do not easily support.

Commercial applications: Large commercial insulation projects, industrial facilities, cold storage construction, and roofing applications often require the output, hose length, and sustained production capability of diesel rig platforms.
