S500-CF-209 - Hangsterfer's S-500 CF Vegetable-Based Coolant Drum

Advanced Chlorine-Free Metalworking Fluid

Hangsterfer's S-500 CF is a premier choice for modern machine shops requiring high-performance cooling and lubrication without the environmental and material constraints of chlorinated additives. Supplied in a bulk 209-litre drum, this coolant is designed for high-volume production environments where consistency, tool life, and part quality are paramount. The "CF" designation stands for Chlorine-Free, making this specific formulation ideal for the aerospace, medical, and electronic industries where material certification often prohibits the use of active chlorine.

The S-500 CF utilizes proprietary vegetable-based micro-emulsion technology. Unlike traditional mineral oil coolants, the vegetable base provides superior boundary lubrication due to the natural polarity of the oil molecules. This results in a fluid that clings tenaciously to the workpiece and tool interface, reducing friction and heat generation even under extreme pressure. The result is a significant extension in tool life and a mirror-like surface finish on machined parts. Because it is free of chlorine, sulfur, and heavy metals, it eliminates the risk of stress corrosion cracking in titanium, high-nickel alloys, and stainless steels.

Operational efficiency is further enhanced by the fluid's excellent biostability. Hangsterfer's S-500 CF is engineered to resist bacterial and fungal growth, preventing the common "Monday morning smell" associated with degrading coolant sumps. This stability translates to longer sump life, reduced disposal costs, and less downtime for machine cleaning. The 209-litre pail ensures you have an ample supply for charging central systems or multiple standalone CNC machines, providing a cost-effective solution for busy industrial facilities.

Safety and operator comfort are built into the formula. The non-toxic, vegetable-based composition is gentle on skin, reducing the likelihood of dermatitis among machinists. It runs clean with minimal residue, keeping machine windows clear and work areas safe. Whether you are performing heavy-duty milling, turning, or grinding, S-500 CF provides the versatility and performance required to meet tight tolerances and strict production deadlines.
