Our 1104 ElectropaK engines set the industry standard for prime and standby power generation. The 4 cylinder, 4.4 litre engines are smooth and quiet in operation. They can also be electronically controlled, giving you the right fuel combustion for the load applied to the engine. The engines deliver 43.7-126.5 kVA, meeting the key power nodes.
