load bank
Our load banks are designed to provide a stable and controllable load for determining the performance characteristics of AC generators. A load bank verifies the rated power of a generator set; it verifies if the engine is properly sized of has the sufficient mechanical power (kWm) to the drive the alternator at full load; it checks the efficiency of the cooling system; it detects problems of the generator; it decarbonizes engine and prevents wet stacking of diesel engine in generators operating on light load.
Designed for durability and convenience with its heavy duty casters for mobility during generator load testing. Uses low heat emitting resistive elements to minimize heat conduction. Metal sheathed elements with cooling fins made from high grade nickel resistance wire in U-type form. Built in heavy duty industrial fan blowers as cooling system of the unit. These blowers can be powered internally by the dummy load itself or by external power supply.
