Industrial fluids, lubricants and coolants are not only your facility’s lifeline; they’re a powerful hidden asset. For example, machining coolants are an important component of every metalworking operation. Coolants improve machinability, increase productivity and extend tool life by cooling and lubricating the work piece and cutting tool.
However, when performing these functions, coolants quickly become contaminated with foreign materials such as metal chips and fines, tramp oil, bacteria and dissolved salts. This contamination causes the coolants to lose their effectiveness and develop foul odours. Hence, most coolants are used only once and then discarded, but this common practice is very costly and wasteful –– adding a large portion to a business’s production costs.
Developing and implementing a coolant maintenance programme can help minimise contamination, prolong coolant life and reduce the frequency of disposal. With Lubriserv’s coolant management programmes including monitoring of concentrations, ph values and dipslides – machining coolants can be made to be more productive, more predictable and an effective tool for immediate, significant cost reduction.
By removing contaminants, a coolant’s effective life is prolonged and in turn, reduces production costs caused by regular coolant replacement.Chips and fines produce surfaces for bacteria to grow on. Free oils produce food source for bacteria and surface films that prevent oxygen from dissolving into the coolant. Free oils also deplete oil soluble components of the coolant and reduce the cooling capability of the metalworking fluid. Dissolved salts affect tool and coolant life, foaming characteristics, filtering efficiency and emulsion stability.Learn more about the most frequent contaminants and how to control and prevent them.

When a coolant is in use, heat and contaminants can change its composition and performance. Routine monitoring of coolants for quality is necessary to optimize performance and prevent problems. Include monitoring pH and maintaining concentration in a coolant maintenance programme.
A change in pH can quickly deteriorate coolant quality, corrode metals and irritate skin. Proper coolant pH operating ranges are specified by the manufacturer. Within the proper pH range, corrosion and bacterial growth are minimized. For most coolants this range is 8.5 to 9.2. Drops below the recommended limit may be a symptom of a bigger problem and are most likely caused by excessive bacteria or excessive diluting. There are common practices to correct low pH level of coolants, but some pose even a larger problem when exercised. For example: Adding chemicals to coolants on a frequent, ongoing basis to condition and restore its pH is a short-term solution only. This practice cause more serious problems in the future such as the buildup of dissolved solids on the coolant. Using low-cost pH measuring tools (such as portable pH meters and pH paper) to monitor pH levels of coolants can help determine when pH needs adjusting. However, for specific and professional recommendations about maintaining coolant pH, you will need an expert.
Maintaining the proper coolant-to-water ratio is critical because coolants are designed to perform best at specific concentrations. Overly diluted coolant may reduce tool life, and concentrated coolant results in using more coolant than necessary. The same is true for coolant additives. Lubriserv can provide information on proper coolant concentrations for specific applications. We have refractometers that provide accurate measurements to determine the coolant-to-water ratio and are fairly inexpensive and simple to operate. Titration kits, used by some companies, are another way to maintain proper concentration, but refractometers are technologically advanced and more preferred. Coolant metering or feed pumps can also improve the rate at which coolants are added. In addition to monitoring pH and coolant concentration, a comprehensive coolant maintenance programme should include monitoring tramp oil concentration, suspended solids, alkalinity, spot corrosion of parts and bacteria count.
