Quench Oil Purification

Protecting Your Quenching Fluid

Quenching is a critical operation. Your quench oil has been carefully formulated and blended to provide precise quenching characteristics and fit a specific “cooling curve.”

But your quench oil (or non-oil quench fluid) is so delicate. During the ordinary course of the workday, it’s steadily being degraded: Oxidation and cracking lead to increasing levels of insoluble materials and volatile products. These reduce the performance of your quench bath and can easily lead to non-uniform hardening. Alarmingly, the build-up of sludge and tar deposits in your quenching oil tanks and on your heat exchangers begins to degrade performance long before you’ll notice gross contamination—let alone see telltale signs, like increased viscosity, reduced finish quality, or slower quenching speeds.

Custom Quenching Oil Filtration Solutions

Your operation is unique: No one else in the world is handling the exact same materials, in exactly the same setting, using exactly the same quench oil formulation, under exactly the same conditions. 

But most filtration solutions for reducing gross contamination in your quench oil are generic. No one can meet a unique challenge with a generic solution.

Oil-based process fluids are significantly cheaper to purify and recycle than to purchase every time they degrade. To protect your quench oil, you need a team with a process-oriented approach—one that takes into account every unique aspect of your process.

Our process is straight forward:

First, we work with you to agree on a specification for your fluid’s particulate contaminants, water removal, and additives. Typically, these specifications are based on SAE (Society of Automotive Engineers), AGMA (American Gear Manufacturers Association), or ISO (International Standards organization) classifications. They might include viscosity, additives such as rust and oxidation inhibitors, anti-wear agents, extreme pressure, etc.

Next, we develop a strategy with you to segregate and collect different contaminated oil types on an ongoing basis, to prevent cross-contamination. Based on the standard life of your oils or continuous laboratory testing, we create a purification schedule. Our filtration and purification process allows us to maintain your industrial oils at your desired ISO cleanliness code, and guarantees the lowest water content in the industry. We’ll also analyze your oil and return it to its original OEM state through an additization process. (This analysis is necessary, especially if heat and water cause oxidation of your oil.)

Finally, we issue a report that documents the results, before returning the oil to your system for reuse (upon your approval).

Taking Quench Oil Filtration Further

Lots of companies will install quenching oil filtration in your plant.

We can go further than anyone else: Trucent can install a team. Your in-house Trucent team will run and manage your custom quench oil filtration system on a daily basis. They handle quench oil buying, then monitor and maintain that oil at appropriate levels and concentrations for your operation. When that quenching fluid is finally spent, we’ll dispose of it (and your other fluids) with minimal negative impact to your business and our world.

No one else offers this level of comprehensive quench oil filtration and purification service.

Every solution begins with a conversation. Contact us today to start that conversation, or schedule a no-obligation site visit and inspection. Let’s find a better way to keep your quench baths clean.


All-in-One Oil Purification and Filtration

Trucent provides comprehensive oil purification solutions to meet your fluid filtration challenges. We can help you maintain your existing centrifugal oil cleaners—or design an entirely new contaminant removal solution. We can install one piece of equipment or install a team to manage all your filtration technology on a daily basis. The goals remain the same: Better quench oil, reduced costs, higher quality parts.

Transmission Plant Saved by Mobile Oil Purification Service


Many of the problems associated with dirty or contaminated oil can be solved through onsite centrifugal purification to purify oil. This technology can positively impact production, quality, costs, waste disposal, and environmental issues.


In this case, the emergency oil remediation service saved $17,300 in oil costs, reduced downtime and saved tooling and allowed for continued production.

“Quick responses, personal service, and knowledgeable technicians are able to achieve desired results with little fuss or disruption of our process.”
