Product Overview
The AKSA APD25A is a compact diesel generating set designed for dependable standby and prime power use across residential backup, small commercial premises, farms, workshops, site cabins, and light-duty power applications. It delivers 25 kVA / 20 kW standby power and 22 kVA / 17.6 kW prime power, making it suitable for installations requiring stable 400/230V, 50Hz, 3-phase electrical supply.
Powered by an AKSA A4CRX24 diesel engine, the APD25A uses a 4-cylinder, 2.545-litre, in-line diesel engine running at 1500rpm. The engine is naturally aspirated and water cooled, with mechanical governor control, replaceable fuel, oil and dry element air filters, cooling radiator and fan, starter battery system, flexible fuel connection hoses, manual oil sump drain valve, industrial exhaust silencer, steel bellows, and a 12/24V DC starter and charge alternator system.
The generator is supplied with an AKSA AK 218 brushless alternator designed for reliable 3-phase output. The alternator uses brushless single-bearing construction, revolving field design, Class H insulation, automatic voltage regulation, and stable output performance for compact standby and prime power loads.
Control and protection are handled by the DSE6120 control panel. The controller supports automatic mains failure operation, generator monitoring, operating status display, alarm indication, engine and alternator protection, and shutdown handling. The APD25A is available in open or sound-attenuated canopy configuration depending on installation requirements.
