BIOL Lemon Metalworking Fluid

What is BIOL Lemon

BIOL Lemon is a synthetic water-miscible MWF. It was developed not as a universal fluid with maximum lubricating performance, but primarily for operating conditions where resistance to microbiological deterioration of the working fluid and corrosion protection of metal surfaces are important.
For this reason, BIOL Lemon was used for many years in plants with circulating MWF systems where bacterial contamination of the working fluid was a recurring problem.

Biological stability of the working fluid

Enhanced biological stability was one of the main objectives in the development of BIOL Lemon. The formulation is intended to suppress the development of microorganisms in the working fluid and reduce the risk of rapid microbiological deterioration.
This was particularly relevant for large circulation systems. High biological stability, however, does not replace proper system cleaning and maintenance.

Corrosion protection

Another important feature of BIOL Lemon is the corrosion protection provided by the working fluid. This is relevant when machining cast iron and steels and in circulation systems where the MWF remains in continuous contact with workpieces and equipment components.
Actual performance depends on concentration, condition of the working fluid, water quality and operating conditions.

Suitable machining operations

BIOL Lemon is most appropriate for operations that do not place high demands on the lubricating performance of the MWF.
It can be used for turning, milling, grinding and other cutting and abrasive machining operations within its performance range.
Historically, the product has been used primarily for machining cast iron and low-alloy steels.

Working concentration

The recommended BIOL Lemon working concentration is 3–5%. The exact concentration within this range should be selected according to the machining operation, material, load and system condition.
Increasing the concentration arbitrarily does not turn BIOL Lemon into a high-lubricity MWF.

When to choose another MWF

BIOL Lemon is a previous-generation product. For new equipment or more technically demanding machining operations, it should be compared with more modern MWFs.
Another fluid is generally preferable where higher lubricating performance is required, heavy-duty cutting conditions are used, a material requires a specialised formulation, or a more modern general-purpose MWF is needed.
In such cases, BIOL Lemon should be compared with other products in the BIOL range.

System preparation

Before changing to a new MWF, assess the condition of the tank, piping and other parts of the circulation system.
This is particularly important when the previous working fluid already shows signs of bacterial contamination. Filling a heavily contaminated system with fresh fluid may shorten its effective service period even when a biologically stable MWF is used.

Preparing the working fluid

Prepare the working fluid by diluting BIOL Lemon concentrate with water to a concentration of 3–5%. In industrial systems, ensure uniform mixing of the concentrate with water.
During operation, monitor the concentration periodically and adjust it according to the actual condition of the working fluid.

Operation

Stable MWF performance depends not only on concentration but also on the overall condition of the system. Monitor metal fines and chips, tramp oil, tank contamination, signs of microbiological deterioration and changes in the condition of the working fluid.
Biological stability does not mean that the circulation system can operate without cleaning and maintenance.

Safety and storage

When handling the concentrate and working fluid, follow the applicable product safety documentation and industrial hygiene requirements and use appropriate personal protective equipment.
Store the concentrate in its original closed packaging under the conditions specified for the product.

When BIOL Lemon is a suitable choice

• a circulating MWF system is used;
• bacterial contamination of the working fluid has been a recurring problem;
• corrosion protection is an important requirement;
• cast iron and low-alloy steels are the main materials being machined;
• the operation does not require high lubricating performance;
• an economical synthetic MWF is required for these operating conditions.

FAQ

What is the recommended concentration of BIOL Lemon?
The recommended working range is 3–5%.
What is the main feature of BIOL Lemon?
Its primary focus is biological stability of the working fluid and corrosion protection.
Why was BIOL Lemon used in circulation systems?
It suited plants where bacterial contamination of circulating MWF was a significant operating problem.
Does BIOL Lemon provide high lubricating performance?
No. This is not the product’s main strength. For operations with higher lubrication requirements, another MWF should be selected.
Is BIOL Lemon a universal MWF?
No. It is best used where its characteristics match the specific machining task and system conditions.
Does a biologically stable MWF eliminate the need to clean the system?
No. Biological stability does not replace proper cleaning and maintenance of the circulation system.
