Open diesel generators have a straightforward design which enables easy operation of maintenance and repairs. They tend to be cheaper than the enclosed types. These generators are more suited for areas with heavy machinery such as industrial zones, construction sites, and remote rugged areas where lesser noise is acceptable. The open structure maintains good airflow which results in cooler engine temperature and better operating efficiency. However, they are more vulnerable to external elements like sand, water, and strong wind. These units should be placed in a well protected location in order to prevent damages and ensure safe operation. Regularly scheduled maintenance like engine servicing, fuel system servicing, and electric system servicing are important for the proper functioning of open diesel generators
