Finning's rental load banks provide electrical loads for testing power sources like generators and uninterruptible power supply (UPS) systems. Load banks also reduce wet stacking (fuel entering an engine's exhaust system), which can occur in highly cyclical loads or light loads in diesel and natural gas applications.
