Any stationary genset: to avoid the common problem of ‘wet stacking’ when the diesel engine runs at insufficient load causing unburnt fuel to accumulate in the exhaust system, which can interfere with injectors, engine valves and the exhaust system, including turbochargers, thereby reducing performance; The appropriate load can be achieved by providing an additional load by means of a resistive load bank equipped with an automatic load control device; this increases the service life of the diesel engine by up to four times and increases its efficiency;
