Wacker Neuson G625


Serious power for industrial applications 

The G625 mobile generator provides all the power needed for larger applications. The rugged 16L Volvo Tier 2 flex engine is housed in a heavy-duty sound attenuated enclosure, perfect for applications requiring large amounts of power and quiet operation. Capable of paralleling, the G625 can easily be scaled up to meet even higher power demands. The integration of many standard features provides ease of operation and maintenance. A digital controller monitors and protects the generator and engine while providing continuous operating data on an easy to read LCD display.

  • Deep Sea 8610 controller and motorized circuit breaker allow paralleling operation (up to 32 units). Connections provided for synchronization communication between generators (input/output).
  • Extensive premium features including battery disconnect switch, circulation coolant heater, engine oil drain with manual pump, low coolant shutdown, dual stage Racor fuel filter for water separation, battery charger and camlock electrical connections are all standard.
  • Simple voltage selection made with the use of a two position link board to reduce connection errors. GFCI outlets and 50 Amp convenience outlet
  • Single point lift eye as well as integrated fork pockets for easy handling.
  • 3-way fuel supply valve allows for easy switch to external built fuel tanks. Standard environmentally friendly features include 100% fluid containment with liquid level alarm, fuel level gauge at fill point.
