We're looking to procure 15 units of oil field generators with a power rating of 260kw. It's important that all units come in an all-black color finish to meet our project specifications. Additionally, we would appreciate any information regarding lead times for delivery, warranty options, and available payment terms. If you have any documentation or brochures that detail the features and specifications of the generators, please include those as well. Your prompt response will help us make a timely decision. Thank you!
