Our services in detail
Condition monitoring
Measurement and monitoring of your processes in accordance with applicable regulations (e.g. TRGS 611) through constant control and adjustment of the parameters and the associated key figures. Digital documentation of measured values and measures via our LABUS Service Portal (LSP).
Analysis of the cooling lubricant possible in our own service center. Special analysis as required.
Product selection
The selection of the right cooling lubricant and process medium depends on many parameters. We support you in selecting the optimum product for your specific application.
Machine cleaning
Machine and system cleaning from individually filled machines to large central systems (100 m3).

Warehouse management
The storage of cooling lubricants must meet many requirements. These include support for storage and handling regulations as well as professional and environmentally friendly disposal. We support, advise and, if you wish, take responsibility for your entire cooling lubricant storage facility.
Treatment by means of "bypass filtration"
In this process, oil-water phases are separated and deposits are removed and cleaned by filtration. The result is a clean product that is suitable for direct reuse.
Recycling & disposal
We handle the processing and disposal of your used oils and emulsions in collaboration with our sister company, Südöl Recycling GmbH. Through analysis, the joint establishment of criteria, and the subsequent processing of your used oils, we can help you significantly reduce the costs that would otherwise be incurred for disposal and the purchase of new oils.

Filter management
With our extensive product portfolio in the field of filtration of liquid media (oils, cooling lubricants, etc.), we offer you the appropriate filter options for your specific requirements.
Filter fleece
Filter fleeces are used for cleaning cooling lubricants, low-viscosity oils, washing liquids and other low-viscosity liquids.
During machining processes (grinding, milling, turning, drilling and honing), optimum filtration is absolutely essential in order to separate solids and residues from the liquids.
Depending on the flow rate, particle size, viscosity and degree of purity required, different types of filter fleece are used. We are happy to offer you a filter fleece that meets your individual requirements.

Filter elements
By using filter elements, particles, dirt or other impurities can be separated from liquids. Depending on the application, these may differ in terms of material or pore size.
Possible filter elements
- Filter cartridges
- Filter bag
- Hydraulic filter

Device management
ZG-Fluid-check Pro
Smart fluid management for the industry of tomorrow
With the Extension Module 2.3, Zeller+Gmelin offers an innovative solution for the automation of cooling lubricant supply. The stationary device monitors the tank level precisely and ensures that it remains virtually constant at the target level by means of automated refilling. The tank is filled with ready-mixed emulsion, which ensures consistent quality and optimum supply to the system.
Areas of application
- Monitoring and control of cooling lubricant tanks
- Automation of fluid management in interlinked and decentralized systems
- Direct compatibility with Fluid Check Pro 2.3
Advantages at a glance
- Ensuring a constant tank level
- Documentation of system-specific data
- High cost efficiency through automation
- Industry 4.0 integration thanks to cloud connection
