Def Replenishment System

Herc Rentals’ DEF Replenishment system is the smart way to manage diesel exhaust fluid required by Tier 4 Final diesel engines. This system extends runtimes by monitoring the DEF level in diesel powered generators and automatically refills DEF into the generator DEF tank unattended.

Features and applications include:
- Stacking corners with lifting points provide easy lifting and reduce storage space
- Fork pockets on all four sides and tie-downs to ease jobsite maneuverability
- Reduces costly refilling and maintenance
- Complements applications using external fuel tanks - Automatically maintains fluid level on one or two engines simultaneously
