Metalworking contaminates cooling lubricant with chips, abrasion and tramp oils, which shortens tool life, jeopardizes tolerances and causes machines to break down. KÖBO ECO>PROCESS builds cooling lubricant treatment systems that filter out coarse to very fine particles, separate out tramp oils and return the cleaned medium. This saves you thousands of liters of cooling lubricant per year and significantly extends tool service life.
Cooling lubricants become contaminated with chips, abrasion, sludge and foreign oils. A cooling lubricant treatment system continuously cleans the medium, separates impurities and returns the cleaned cooling lubricant to the machines in a cycle.
Without reconditioning, tool and machine costs increase dramatically. Pumps clog, machine rooms become dirty and components no longer meet quality requirements. In addition, thermal loads often lead to
A coolant preparation system ensures a permanently clean and controlled-temperature medium. Temperature stabilization keeps the viscosity of the cooling lubricant constant, which improves the dimensional accuracy and surface quality of the workpieces.
KÖBO ECO>PROCESS offers a wide range of coolant preparation systems: From individual units to fully automatic central system. All systems can be modularly expanded and flexibly integrated into new or existing production lines and processing plants.

The pressure belt filter is intermittently supplied with contaminated cooling lubricant. Under overpressure, the medium flows through a circulating filter belt or fiber fleece, while the cleaned coolant flows into a clean container.
|
– Fully automatic for high dirt loads |
|
|
The cooling lubricant is sucked through the filter medium with negative pressure via a suction chamber below the filter belt. During the discharge and cleaning cycle, a separate regeneration tank maintains the machine supply. |
– Continuous operation without interruption |
|
|
The folding belt filter works like a pressure belt filter, but is suitable for lower throughput rates. Users often use the hinged belt filter as secondary filtration after precoat filters. |
– Compact design for limited space |
|
|
A carrier medium carries a filter aid such as cellulose or diatomaceous earth, which retains the finest particles. After saturation, a short, automatic regeneration and new precoating takes place and the filtration process continues.
|
– High filtration quality down to below 10 µm |
|
|
The chip separator separates coarse chips directly at the point of origin. It relieves downstream filter systems and prevents backlogs in the cooling lubricant circuit. |
– Design with rectangular tank and integrated scraper conveyor |
A cooling lubricant treatment system cleans the cooling lubricant in a clearly structured process. Cooling lubricant temperature control may also be included. Each stage fulfills its own task in order to keep the medium permanently in circulation.
Modern systems are equipped with powerful filter system pumps that ensure a constant flow rate even with a high dirt content. Backwashing devices and differential pressure controls clean filter elements automatically and ensure uninterrupted operation. They are controlled by sensors and control units that detect the degree of contamination and trigger cleaning cycles automatically.
Our filters keep the cooling lubricant free of the finest particles. Machine rooms remain clean and pumps work without clogging.
Prepared coolant significantly extends tool life. Fewer tool changes means lower costs and longer machine runtimes.
Clean cooling medium prevents dimensional deviations and surface defects. Series components meet dimensional and quality requirements, even in large quantities.
Recirculation reduces the need for fresh fluid by thousands of liters per year. At the same time,
Automatic cleaning and sensor control maintain filtration at all times. This means that the systems run smoothly even in three-shift operation.
Our filter solutions are designed for cooling lubricant volume flowsof between 200 and 30,000 l/min. They offer cleaning stages with single or multiple filters connected in parallel, which – depending on the respective process parameters – enable a solids separation efficiency of less than 10 µm.
A coolant preparation system reduces operating costs on several levels. Clean coolant extends tool life by up to 50% and saves tool costs in the five-digit range per year. At the same time, the need for fresh coolant is reduced, often by several thousand liters per year. Disposal costs are also reduced. In many projects, the investment pays for itself after just 12 to 18 months.
Are you planning a new coolant preparation system or would you like to modernize your existing technology? Then talk to us directly. We will develop a concept that is precisely tailored to your production and ensures consistent processes.
Cooling lubricants contain metallic and non-metallic particles from machining, oils from lubricants and chemical or biological residues. Without treatment, the quality drops rapidly. Cooling lubricant treatment systems permanently separate these contaminants and safeguard the production process.
Magnetic filters remove magnetic particles regardless of their size. Oil skimmers separate floating foreign oils. Mechanical filter fleeces retain larger particles, but are expensive as consumables. Heat exchangers ensure constant coolant temperatures. Modern treatment systems combine these processes.
