For many industries, it is critical to have a temporary power solution ready in case the city’s power grid fails, or if your alternative energy sources are temporarily down. Other common temporary power applications include:

  • Facility shutdowns:  What happens when your business shuts down temporarily? When you rent an industrial generator, you can rest assured that you can continue to provide services without downtime.
  • Severe weather:  When natural disasters strike, often businesses aren’t prepared. Altorfer Cat specializes in emergency generator rentals meaning you can spend less time worrying about how to keep your business running, and more time working.
  • Special events:  Are you planning a large tent event, concert or other outing this spring or summer? Keep your event powered with our industrial generator rental options. And don’t forget to check out our Temperature Control rental inventory to make sure everyone stays comfortable, not too hot or too cold.
  • General construction:  What do you do when your construction worksites do not yet have a power source? You can rent one of Altorfer’s industrial generators and use it as the primary power source initially, then transition its use to an industrial backup generator in case of emergencies. This helps your project stay on track, and keeps your bottom line low.
  • Healthcare facilities:  If the lights go out and you need emergency backup power at your hospital, let Altorfer Cat supply you with a generator so you can ensure that your patients have access to life-saving devices no matter what.
  • Grocery stores and restaurants:  If you work with food, you don’t want to be caught off guard when the power goes out. One of our rental backup generators can ensure that your food does not spoil and your registers can keep charging.
