We are pleased to introduce “Coolant Fresh CF-50”, one of our key focus products, designed to extend the life of water-soluble cutting fluids. In this article, we’ll highlight its features and the benefits of implementing it in your operations. Developed by NMC—a company specializing in rust inhibitors, cleaning agents, and cutting fluids—this product was inspired by real challenges encountered at machining sites and was launched approximately a year ago.

What Causes Contamination in Water-Soluble Cutting Fluids?

In machining environments, it’s inevitable that lubricating oil and rust-preventive oil will mix with the water-soluble cutting fluid during use. While these oils may initially separate and can be removed with an oil skimmer, over time, the following issues tend to occur

△ The cutting fluid and oil mix, causing stickiness and the formation of foreign substances
△ Fine sludge particles build up, contaminating the inside of the machine
△ Bacterial growth accelerates, leading to foul odors and fluid degradation
△ The coolant’s cooling and penetration performance deteriorates

Once the fluid reaches this condition, an oil skimmer alone is no longer effective, resulting in the need for frequent coolant replacement and cleaning.

Reasons to Choose CF-50｜Eliminate Stickiness and Odors with a Simple Connection

▲ Recommended Installation: Connect directly to the base coolant line – no power supply needed

▲ Installation example

The “Coolant Fresh CF-50” operates simply by connecting it to the line of the base coolant (the pump used to flush away chips). Since it requires no power or electricity, installation is extremely easy. The unit breaks down and disperses heavy oil particles that have accumulated in the cutting fluid, restoring them to a state where they can once again be efficiently removed again by an oil skimmer. As a result, the coolant stays closer to its original condition, helping to reduce both odors and stickiness.

【Key Benefits】
●Reduces cutting fluid stickiness
●Suppresses fluid degradation and unpleasant odors
●Enhances oil skimmer recovery efficiency
●Improves removal of fine sludge
●Makes tanks and machine interiors easier to clean
●Restores visibility through splash guard windows

Proven Performance with Over 400 Units Installed｜Effective in Reducing Costs and Enhancing Environmental Conditions

Since its launch, more than 400 units of the “Coolant Fresh CF-50” have been installed, receiving high praise from numerous satisfied customers.

Here’s what our customers are saying:
• “The stickiness is gone, and our work environment is much more comfortable.”
• “We’ve significantly reduced coolant replacement frequency, which helped lower our operating costs.”
• “After seeing the results from one unit, we didn’t hesitate to install 30 more.”

▲ After 2 months of use: Noticeable reduction in contamination inside the machining area

Chemical-Free and Environmentally Friendly

While many companies have traditionally relied on chemical agents as a temporary fix, “Coolant Fresh CF-50” delivers lasting results through physical treatment of oil contamination—completely without the use of chemicals. This innovative approach offers several key benefits
●No need for frequent replenishment or chemical purchases
●Reduced environmental impact
●Safe and sustainable long-term operation

If you're experiencing issues in Vietnam with the lifespan of water-soluble cutting fluids—such as stickiness, foul odors, or fluid degradation—we highly recommend trying the “Coolant Fresh CF-50” and experiencing its effectiveness firsthand.
