By Hy-Pro Marketing on Wed, Jul. 12, 2023

A New Episode of Factory Side Chat is now available on Apple Podcasts, Spotify, Podbean, and YouTube.

Episode 12, Saving Time, Money, and the Planet: The Evolution and Benefits of Reducing Oxidation By-Products and Varnish

In this episode, we discuss the evolution of the industry's approach to varnish and review strategies to reduce oxidation and varnish production and extend oil life, saving time and money and increasing sustainability.

Hy-Pro’s Scott Howard leads this discussion with two of the most experienced and influential thought leaders in the industry: Peter Dufresne, CEO of EPT Clean Oil, and Aaron Hoeg, General Manager for Hy-Pro Filtration.

Key Takeaways:

  • The industry’s approach to varnish control has changed, and new technologies are making it easier to solve varnish issues and prevent formation.
  • Varnish is a complex problem, but there are a number of strategies that can be used to prevent it from forming.
  • By following these strategies, you can extend the life of your oil and save time, money, and resources.

Why You Should Listen:

  • This episode contains valuable information on how to prevent varnish formation in industrial oils.
  • The guests are two of the most knowledgeable experts in the industry.

Getting to Know Demulsibility

By Brad Bainbridge on Thu, Mar. 25, 2021


What is Demulsibility?

Demulsibility is the ability of oil to separate from water. Oil and water naturally separate because like molecules attract each other. Oil sticks with oil, water sticks with water. Oil is "hydrophobic", or "afraid of water," which is a benefit when it comes to fluids like turbine oil.

Dynamic Filter Efficiency


What is Dynamic Filter Efficiency?

Dynamic Filter Efficiency matches filter testing with real-life conditions. 

All hydraulic and lube systems have a critical contamination tolerance level that is often defined by, but not limited to, the most sensitive system component such as servo valves or high speed journal bearings. Defining the ISO fluid cleanliness code upper limit is a function of component sensitivity, safety, system criticality and ultimately getting the most our of hydraulic and lube assets.

Fluid Life Extension

By Brad Bainbridge on Thu, Mar. 11, 2021

Extending Fluid Life Saves Money and Helps the Environment

Our mission is to make our customers as efficient as possible, and we achieve that with the highest quality filtration products and total system cleanliness strategies to maximize uptime, productivity and prevent costly fluid contamination related failures. Been there. Done that. Going to do it again tomorrow. But that's not the only way we make our customers efficient. Extending the useful life of in-service fluids pays big dividends in reliability, saves money on premature fluid replacement costs, and reduces the environmental impact of industry by reducing the amount of fluids used and discarded. Enhancing reliability, saving money, and protecting the environment are not only good business, they're our responsibility. To help reduce oil usage, let's first understand why fluids are condemned and prematurely replaced.
