What Helped Lindberg Heat Treating Company Reduce Oil Contamination by 70%
Cleaner Wash Systems and Reduced Downtime Through Improved Quench Oil Recovery
Heat treating operations rely on wash systems and quench tanks to clean metal components after thermal processing. Over time, these systems accumulate quench oil that separates from cleaning fluids, reducing efficiency, increasing maintenance requirements, and driving higher operating costs.
At Lindberg Heat Treating, a solution from Abanaki Corporation was installed to continuously remove floating quench oil from heated spray wash tanks, helping restore system performance and improve oil recovery efficiency.
The result was a significant reduction in oil contamination, improved system uptime, and measurable recovery of usable quench oil.

The Challenge: Quench Oil Build-Up Impacting System Efficiency
In heat treating operations, quench oil is essential to the process but becomes a recurring contaminant when it migrates into wash systems. At Lindberg Heat Treating, oil contamination developed through:
- Carryover of quench oil from processed parts
- Continuous operation of heated spray wash tanks
- Natural separation of oil from aqueous cleaning solutions
- Accumulation of floating hydrocarbons across multiple tanks
This led to several operational challenges:
- Persistent oil layers forming on wash tank surfaces
- Reduced cleaning effectiveness in wash systems
- Frequent tank shutdowns for manual cleaning
- Increased disposal costs for contaminated fluids
- Loss of recoverable quench oil
The facility required a continuous method to control surface oil and reduce maintenance interruptions.
The Solution: Abanaki Belt Oil Skimming System and Measurable Results
To address these challenges, Lindberg Heat Treating installed belt oil skimming systems from Abanaki Corporation on multiple heated spray wash tanks.
The system continuously removed floating quench oil from the surface of the tanks, preventing buildup and allowing oil to be recovered rather than lost to waste streams or system contamination.
This implementation delivered clear operational improvements:
- Continuous removal of floating quench oil from wash tanks
- Reduced manual cleaning and maintenance requirements
- Lower disposal volumes of contaminated fluids
- Improved wash system consistency and reliability
- Stable operation in heated industrial environments
Measurable Results
- Up to 70% reduction in oil contamination in wash tanks
- Significant reduction in oil buildup over operating cycles
- Longer runtime between required tank cleanouts, reducing production interruptions
- Improved recovery of usable quench oil, reducing waste and increasing resource efficiency
- Lower overall maintenance, minimizing manual intervention and cleanup
These results improved both system performance and resource recovery while reducing operational disruptions.
Why Heat Treating Facilities Use Belt Oil Skimmers
Heat treating operations use belt oil skimming systems to:
- Recover valuable quench and process oils
- Reduce tank cleaning frequency
- Improve system uptime and stability
- Lower waste handling and disposal costs
- Maintain consistent wash system performance

Frequently Asked Questions
Why does oil accumulate in heat treating wash systems?
Oil separates from water-based cleaning fluids and rises to the surface during continuous operation.
What is the main benefit of oil skimming in these systems?
It continuously removes floating oil, preventing buildup and reducing maintenance needs.
Is the 70% reduction typical?
Performance varies by system, but significant reductions in surface oil accumulation are commonly reported in similar applications.
Can recovered oil be reused?
In many cases, yes—depending on contamination levels and process requirements.
