BIO-CIRCLE L Evo: Planning Parts Cleaning with a 200 L Drum
A clean component is the goal. A well-organised cleaning process is how you get there. BIO-CIRCLE L Evo can be used to clean oil- and grease-contaminated parts in designated BIO-CIRCLE systems. The 200 L plastic drum provides a packaging option for businesses with corresponding supply requirements.
This guide brings together product selection and practical use: which machine is compatible with the cleaner, which operating conditions matter, and how should you organise replenishment, checks and cleaning bath maintenance?

What BIO-CIRCLE L Evo contributes to the cleaning process
BIO-CIRCLE L Evo is an aqueous cleaner containing microorganisms. The manufacturer lists oils, greases, corrosion protection waxes and more stubborn organic deposits among its applications. In the intended recirculating system, microorganisms can break down oils introduced into the bath, helping extend the service life of the cleaning fluid.
Compatible systems include BIO-CIRCLE brush-type parts washers and suitable high-pressure parts cleaning machines. Approval for the specific machine and the workpiece to be cleaned remains essential.
| Container | Manufacturer part no. | Selection guidance |
|---|---|---|
| 20 L plastic canister | A02093 | Smaller supply requirements and targeted replenishment. |
| 200 L plastic drum | A20093 | Higher overall demand and centrally managed stock. |

View BIO-CIRCLE L Evo 200 LBasic settings: guideline values and clear operating requirements
The following information is provided for guidance. The current product data sheet and your machine's operating instructions take precedence. Temperature, fill volume and cleaning action are particularly dependent on the equipment.
| Parameter | Specification | Practical implications |
|---|---|---|
| Working concentration | 100 % | Use as supplied; do not dilute with water. |
| Cleaning fluid temperature | 41–50 °C | Recommended range according to the technical data sheet; observe any differing equipment requirements. |
| HP Vigo example | Recommended maximum: 45 °C | Information from the reviewed operating instructions, edition 04/2026. Check applicability to your serial number. |
| Aeration | Continuous during intended operation | Ensure an adequate oxygen supply; carry out shutdown and maintenance according to the equipment instructions. |
| pH value | Approx. 7–8 at 20 °C | Guideline value from the safety data sheet, not a setpoint for unauthorised chemical adjustments. |
| Cleaning time and pressure | Application-dependent | No universal product values; determine these according to the machine, part geometry and cleaning task. |
Do not add other chemicals: strong acids, alkalis, disinfectants and solvents must not be added to the BIO-CIRCLE L Evo cleaning bath.
Professional workflow: six steps to a defined result
Use this practical framework as the basis for a work instruction tailored to your business.
- Define the cleaning objective. Establish the material, type of contamination and next processing step. A visual inspection for maintenance purposes requires different acceptance criteria from approval before coating.
- Check the component and system. Verify machine approval, permitted load and workpiece compatibility. For sensitive surfaces, first test an inconspicuous area or a sample component.
- Remove heavy contamination beforehand. Collect excess oil and grease separately. The parts washer is intended for cleaning, not for disposing of operating fluids and other consumables.
- Prepare the system for operation. Check the fill level, temperature, aeration and filter condition. Only start cleaning once the intended operating conditions have been reached.
- Clean in a controlled manner. Process the workpiece according to the equipment instructions. On a brush-type parts washer, the flow-through brush assists cleaning; high-pressure machines have their own safety and operating requirements.
- Check and document the result. Inspect critical recesses, edges and contact surfaces. Carry out any required post-treatment and drying. Record deviations and replenishment volumes for the next shift.
Troubleshooting: four typical situations to investigate
The following measures are suggested checks, not a remote diagnosis. Contact the equipment service team if problems persist.
1. Greasy areas remain after cleaning
- Check whether the intended operating temperature has been reached.
- Check access to the affected areas and the mechanical cleaning action being used.
- If the result does not improve, ask the manufacturer to confirm suitability for the specific contamination.
2. The air supply appears to be interrupted
- Check the aeration according to the equipment instructions.
- Have authorised personnel inspect the air diffuser and air supply; carry out any necessary maintenance safely.
3. Too little cleaning fluid reaches the cleaning tool
- Check the fill level and any displayed fault messages.
- Inspect filters and accessible fluid lines according to the equipment instructions; never bypass safety shutdowns.
4. Streaks or moisture are visible before coating
- Do not approve a component for coating solely because one area looks clean.
- Remove residues using the follow-up cleaning procedure approved for the subsequent process.
- Repeat drying and surface inspection.
Cleaning bath care: five tasks for your maintenance routine
- Check the fill level: replace losses with the specified original cleaning fluid and avoid overfilling.
- Keep filters clean: clean or replace strainers, filters and any magnetic separators according to the machine instructions.
- Check the aeration: include the oxygen supply in regular functional checks.
- Assess deposits: have non-degradable solids and sludge removed as part of the specified equipment maintenance.
- Store stock correctly: keep the original container tightly closed, protect it from frost and maintain traceable records of withdrawals.
Equipment-specific example: for the BIO-CIRCLE For U, the instructions specify daily cleaning of the filters and magnet, a weekly aeration check and a thorough inspection at least once a year, among other tasks. Do not apply these intervals to other models without checking their requirements. Before working on internal components, safely disconnect the equipment from its energy supply according to the instructions.
Before painting: parts cleaning does not automatically mean surface preparation
Oil and grease residues, cleaning agent residues and incomplete drying can affect the subsequent coating. Suitability for parts cleaning must therefore not be taken as blanket approval for use as the final cleaning step before painting. Define follow-up cleaning, rinsing where necessary, drying and acceptance criteria to suit the coating system, and first validate the procedure on sample parts.
FAQ: BIO-CIRCLE L Evo in a 200 L drum
Can BIO-CIRCLE L Evo be diluted with water?
No. The cleaner is used ready to use. Do not dilute it or mix in other cleaners without authorisation, including when topping up.
Is the product suitable for aluminium and galvanised parts?
Both materials are listed as compatible in the technical data sheet. Preliminary testing remains advisable for sensitive surfaces, coatings or unusual material combinations. This does not constitute blanket approval for every complete component.
How long will a 200 L drum last?
Container size alone cannot answer that question. Consider the initial fill, the number of machines supplied and measured replenishment consumption. How long your stock lasts is also different from the service life of an individual cleaning bath.
Does “no hazard labelling required” mean no protective measures are needed?
No. According to the safety data sheet, the mixture is not classified as hazardous under CLP. Nevertheless, the handling and protection requirements must be followed. Eye protection is specified where there is a risk of splashing; select suitable protective gloves according to the task and the safety data sheet.
Can used cleaner be poured down the drain?
No. The safety data sheet prohibits discharge into drains or watercourses. Have the used fluid classified according to its actual contamination and send it through an appropriate disposal route. Biological cleaning does not replace proper waste disposal.
Conclusion: plan the process, not just the cleaner
BIO-CIRCLE L Evo in a 200 L drum is a packaging option for businesses looking to supply their parts cleaning operations according to demand. The right machine, correct operating conditions and reliable cleaning bath maintenance are essential. Recording consumption and cleaning results also provides a stronger basis for reordering and process control.
