How do tramp oil separators improve coolant effectiveness and system life?

Removing tramp oil extends coolant life by 2–5x, reduces tool wear, odors, and prevents bacterial growth.

Tramp oils are unwanted machine lubricants that leak into coolant sumps, causing fluid degradation and contamination. PRAB tramp oil separators—such as coalescing units and belt skimmers—efficiently remove free-floating and emulsified oils. This helps maintain fluid integrity and reduces the frequency of coolant replacement.

Case Study: Tramp Oil Separator Extends Washwater Life

Benefits:

• • Improves tool life and part finish by keeping the fluid cleaner
  • Reduces bacterial growth and odor in coolant tanks
  • Minimizes smog and mist from emulsified oils
  • Prevents sticky residue and downstream equipment fouling
  • Extends coolant life by up to 3× in many facilities

Q: What types of tramp oil can be removed?

A: Floating, mechanically entrained, and lightly emulsified oils can be removed with coalescing or skimming technology.

Q: How often should tramp oil be removed?

A: Ideally, tramp oil should be removed daily or continuously using automated systems.
