AC Load Bank Range

  • 400kW - 500kW
  • 800kW - 1000kW
  • 1200kW - 1500kW







The Dual Operation Resistive HACA Range

Auto Load Regulation & Manual Load Control

The HACA load bank range are designed for fixed installations to provide resistive load testing of generators and UPS systems.

Rated for 400kW to 1500kW, 415V, 480V, 600V, 50Hz or 60hz.

Units incorporate vertical force cooling with high powered resistor elements controlled via Manual panel mounted switches or Automatic load regulation to prevent genset wet stacking.

Load banks can also be supplied for both three phase and single phase testing, and with a digital power meter.

Application Note 1

Regular load bank testing of generators provides an essential health check service to prevent diesel engine failure due to wet stacking.
Wet stacking occurs due to under loading of the genset which results in wet un-burned fuel building up in the engine.
This fuel build up will over time line the combustion chamber cylinders and cause a reduction of the engines rating and efficiency which will ultimately cause premature failure of the generator. Running the generator on load of 50% - 100% of the genset rating will allow the engine to reach the recommend operating temperature, which will burn off the choke deposits.
