2025 Generac Mobile Stationary Generators SG175
Keep all your business’s essentials up and running with a Generac 175kW generator. These commercial generators run on natural gas so there’s no refueling and virtually no maintenance. Take advantage of a durable enclosure that utilizes the highest level of noise reduction. Generac is one of North America’s largest suppliers of power generation equipment. For more than five decades, Generac has designed and manufactured diesel, natural gas, and bi-fuel generators that meet the demands of any application.
Features may include:
Enclosure- Generac manufactures its own enclosures, ensuring each unit combines the highest level of durability, noise reduction, weather resistance, and streamlined design.
- Generac builds its spark-ignited engines from the block up utilizing advanced engineering expertise.
- Generac industrial alternators are machine wound, machine inserted, and machine varnished for the ultimate in consistency.
- The Generac Power Zone® Digital Control Platform is a fully integrated and multipurpose family of controllers for Generac’s single genset and Modular Power Systems (MPS) applications.
