Economy engineering corporation offers load banks. These are essentially generator testing equipments, available in capacity from 24 kw to 200 kw and above. Load banks are cost effective and play an important role in standby power generation equipment. The efficiency and life of diesel generators can be dramatically reduced when under loaded. Poor installation of air supply cooling or exhaust systems can also have an effect on the running of a diesel engine. The restriction in use of existing building loads, due to interruption of mains power is a common cause of under loading diesel engines when testing. Repeated running of generators under loaded will cause damage to the diesel engine, resulting in cylinder bore glazing, fowling of exhaust ports and valves, to the point where engines could stall or fail to start on mains power failure. Only load banks can guarantee the condition and the efficiency of standby generators. The necessity to test ups systems and batteries is equally important batteries occasionally require full discharge tests to monitor cell condition. With load banks as peripheral equipment, reliable load testing can be carried out regularly with no interruption to building supply, ensuring that the emergency power system will be able to cope with any power failure.
