T2 DGB

Hydraulic fracturing pump units built on EPA Tier 2 dual-fuel engines that automatically blend natural gas with diesel during pumping. They form the core of a T2 DGB fleet and deliver high-pressure slurry to the wellhead.

Retrofit systems that convert an existing diesel frac engine to dual-fuel operation by adding a gas-air mixer, fuel-injection control, and safety shutdowns. They allow legacy diesel fleets to displace a share of diesel without full repowering.

Electronic control modules and sensors that meter natural gas into the engine intake and dynamically vary the substitution rate based on load, temperature, and knock feedback. They maintain stable combustion across changing frac-stage demand.

Skid-mounted units that filter, scrub, regulate, and meter wellhead or pipeline gas to the quality and pressure the dual-fuel engines require. They remove liquids and contaminants that would otherwise damage the fuel system.

Compressed natural gas trailers, decompression skids, and wellhead tie-in equipment that deliver gas to the blending system when on-site gas is unavailable or insufficient. They provide the gas feedstock for the fleet.

Engineering and equipment packages that integrate dual-fuel pumps, fuel supply, and controls into a complete low-emission pumping spread. They coordinate fuel logistics and substitution monitoring across the full fleet.
