Load bank is compact unit that are coupled to the output of your power generation system such as diesel generators, gas turbine or ups and battery system. The necessity and dependence on power at mining site, oil and gas refining in Hospitals and many other essential Services has meant a rapid growth of backup generators and UPS system for backup power. The increase of Computers and telecommunication equipment demands faultless performance in the event of power down conditions, this can only be Full Achieved By resistive Load testing the Stand by system on installation and at regular intervals.

The Life and efficiency of diesel generators can be greatly reduced when running under loaded. Lousing damage to the engine to a point Where engines could stall or completely fail to start when they are needed most. Load banks are dummy loads designed to simulate the plant load and prove the design, performance and the capacity of the system without interruption to the normal running of your plant.
