Diesel Distribution
Diesel still has a role on many pads, and how it is delivered matters. The Daffy is Nacelle’s automated diesel distribution system, built for operations where diesel remains part of the fuel mix. It fuels the fleet on demand through a closed, metered design, delivering diesel to multiple pumps at once while helping keep personnel out of the hot zone. The Daffy protects productive time, improves safety, and gives operators clear, per-pump visibility into how much fuel each engine is using.

The Daffy Difference
Traditional diesel fueling means trucks, hoses, and crews moving around active equipment, often slowing or stopping operations to refuel. That adds cost, manpower, and risk.
The Daffy automates the process. Diesel is dispensed on demand through a closed, contained system and metered as it is consumed, so refueling happens continuously and safely while the fleet keeps running. Built on a mobile, high-capacity platform, the Daffy fuels multiple pumps at once and pairs with Nacelle’s gas distribution for full dual-fuel visibility.
What the Daffy Delivers
What the Daffy Delivers
Safety
A closed system that reduces spills and crew exposure.
- Closed filling system reduces splash, spills, and static buildup
- Grounded and bonded equipment with double containment at key points
- Automated controls and remote monitoring reduce time spent in the hot zone
Efficiency
Continuous fueling that protects productive time.
- Multiple pumps fueled at once through a multi-reel design, with no need to slow down or stop to refuel
- Faster mobilization and demobilization
- Fewer personnel required compared with traditional truck-and-crew fueling
Visibility & Control
Metered per pump, not just per fleet.
- Fuel metered at each pump and hose reel, not a single fleet meter that only reports stage totals across all pumps
- Coupled with GOALIE hose-reel data to calculate energy consumption per pump, per stage, across diesel and field gas, CNG, and LNG
- Downloadable fuel-usage reports for more accurate ordering and clearer fleet performance insight
