Cleaning of cooling lubricants

In machining and forming processes of metallic workpieces, cooling lubricants (coolants) such as oils, emulsions or aqueous solutions are used. They perform essential functions including cooling, lubrication, flushing and corrosion protection.

Insufficient coolant treatment can lead to negative effects such as:

high temperature rise due to insufficient recooling or reduced lubricating effect

insufficient removal of metallic abrasion or impurities

poor surface quality and low production speed

high wear on the tools/rollers

short service life and high downtimes

high operating and maintenance costs

To maintain the performance and stability of cooling lubricants over the long term, continuous and proper treatment is essential. For this purpose, we offer a wide range of filtration and separation systems – from compact, decentralized single units to turnkey central systems for industrial series applications.

The choice of the appropriate treatment method depends on factors such as particle type, degree of contamination, flow rate and the required level of purity. Our many years of experience enable us to realize the optimal combination of filtration technology and system design for every application.

Even during the design phase of production equipment, proper cleaning of cooling lubricants should be taken into account.

We are happy to support you in implementing a modern and cost-efficient coolant treatment system to:

extension of the service life of the cooling lubricant and thus also a reduction in negative environmental impacts

economical operation of the production processes:

reduced friction during cutting, grinding or forming

optimized heat dissipation

safe removal of the impurities

lower replacement costs for tools and rollers due to the improved service life

maximum recovery and recycling of valuable materials wherever technically feasible

For this purpose, we supply separators, filtration technology and turnkey systems for:

Cooling lubricant cleaning

Cleaning gear oil

Treatment of wash water

Various filtration systems are available for the implementation of efficient coolant treatment. Depending on process requirements, particle size and flow rate, these systems can be combined individually. Our units ensure consistently high fluid quality and stable production conditions – from coarse separation to fine filtration.

Among others, our range includes belt filter systems such as the pressure belt filter, the vacuum belt filter and its compact version, the folding belt filter. These media-free systems operate with endless filter belts or, optionally, with fiber fleece as the filter medium, enabling high flow capacities with consistently stable filtration quality and minimal maintenance requirements.

At higher particle concentrations or when larger chips are present, chip separators are used to ensure effective pre-cleaning of the coolant.

For particularly fine filtration requirements, for example below 10 µm, our precoat filters are ideal. They achieve the highest levels of purity.

As a result, our filtration solutions cover both standard and fine filtration and are designed for flow rates between 200 and 30,000 l/min. Depending on the application, cleaning stages with single or multiple parallel filters are available. This guarantees consistent filtration performance even at high flow rates and ensures long-term process stability.
