About Us

Who Are We?

Nosnhoj Services, Inc. is a Veteran owned and operated company that maintains, services, repairs, upgrades, and/or replaces high speed centrifuges and other separation equipment. We have decades of experience helping companies in a variety of industries keep their centrifuges and factories up and running. Though we are a family run shop, our service technicians can be called on 24/7 to ensure your machines keep operating. We can supply parts, oil, manuals, and any other needs for your company’s Alfa Laval or Westfalia machines.

Established in 2005, NSI was formed in a desire to provide quality service and experience from one contractor regarding the different centrifuges found in many industries. We service companies in the fats/oils, dairy, and many miscellaneous industries with the ability and experience to work in other fields.

We travel all over the United States to handle high speed industrial centrifuges for maintenance, repair, and troubleshooting. We also have over 10,000 sq. ft. of buildings for in-house repairs and stocking of used and new parts.

Many of our clients have been with us for years and much of our business comes through word of mouth. Reach out today to set up centrifuge maintenance, get emergency help or simply to talk to someone about your company’s needs.
