Towable generators are the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. Due to its nature of tow ability it is ideal for small and large job sites. Since multiple electric equipment units need to work at the same time to maximize work capacity, hence it is the ideal choice for any job site.
Portable generators are like stand by electricity arrangements which are capable of powering most of the standard 120/240V electric equipment like fan, blower and lights. Some of the portable generator models are equipped with automatic idle control in order to conserve fuel and lower noise levels. They are not very heavy and can be moved or carried by one or two people.
