NuPresto B120 Booster
The mid-size NuPresto booster: a 125 HP, 2-stage hydraulic booster that keeps compressing as trailer pressure falls. Packaged in a 10 ft Connex with the air cooler outside, or in a 20 ft Connex with the cooler on a side wall and room for cascade storage and fueling controls.
Overview
The NuPresto B120 is built around a 2-stage hydraulic booster platform with more than 3,000 installations worldwide. Flow follows suction pressure: about 235 SCFM with a trailer drawn down to 435 psig, about 1,550 SCFM with a full trailer at 2,900 psig, and about 690 SCFM (4.7 DGE per minute) averaged across the draw-down. Discharge is up to 4,200 psig.
The standard package is a 10 ft Connex with the glycol cooler mounted externally. The 20 ft option moves the cooler to a side wall and leaves space inside for cascade storage, Coriolis metering and a PLC and HMI fueling lane, which is the configuration behind the Mobile CNG Fueling System.

Why NuPresto B120 Booster
Flow that follows the trailer
Two stages let the B120 keep its flow up as trailer pressure falls, so trailers are drawn down further and swapped less often.
Hydraulic compression
A hydraulic cylinder pushes the gas instead of a crankshaft. Variable suction tolerance, unlimited start and stop cycles, no bearings or rod packings in the gas path and a smooth, low-pulsation discharge.
Pass-through equalization
Gas moves trailer to vehicle on differential pressure first and the booster finishes the fill. Less run time, less power, faster turns.
Connex packaging
Factory built inside a weather-tight Connex with the air cooler outside, so the package ships as one lift, connects to gas, power and ground, and runs.
Built and tested in Texas
Assembled, wired and FAT-tested at our Center, TX facility before it ships. Issues get caught in the shop, not on your site.
Typical applications
- Fleet fueling yards and private terminals
- Mobile and temporary CNG fueling stations
- Trailer and virtual pipeline unloading at daughter sites
- CNG trailer testing and trailer-to-trailer transfer
- Bridge capacity during station construction or upgrades
- Remote and satellite fueling
What's included
- Hydraulic power unit, gas cylinders and process piping on one skid

Engineering and aftermarket support
Service, maintenance plans and spare parts support come from the team that designed and built the package. Critical spares, including complete cylinders, are stocked at our Texas facility.
Field service, troubleshooting and remote support are handled by the same team that designed and built the unit.
