With our retrofit offensive, we are setting an example in the fight against inefficiency on machining centers and short turning machines - at as-good-as-0-risk for you! The only cost is a flat installation fee of 999 euros - including logistics and uninstallation if the product is not purchased. The highlight: If the installation does not bring the desired benefit, it will be taken back. The dismantling and all associated costs are in this case naturally contained in the 999 euro. Protect your investment now without risk - benefit from market-leading compact high-pressure efficiency, even for large flushing capacities. The campaign runs until December 31, 2021.

„Our goal is for you to benefit as precisely, quickly, easily and safely in the range of high flushing capacities between 40 and 150 l/min at pressures greater than 30 bar as possible.“

In addition to an increase in output or increased process reliability and improved processing quality, you can easily realize rationalization potential in the 5-digit range, for example, when using 70 bar high pressure - depending on the processing.

The following table shows you the considerable cost savings using the example of a CL4 G-400 eco+ 70/60 or CL3 G eco+ 70/40 with cascade filtration.

Let's do something together against efficiency killers in the retrofit sector at high purging capacities. Profit now. For today and tomorrow.

Two-stage cascading filtration saves consumables and reduces downtimes

When machining on processing centres, a very high chip volume is generated almost continuously. At the same time, high coolant flushing performances are required – but naturally with the corresponding purity in the desired high-pressure operation over 30 bar. As a financially and economically very interesting entry-level solution, Müller offers a two-stage cascading filter system consisting of pre- and fine filters for the combiloop CL4 G-400 eco+ 70/60, combiloop CL3 G eco+ 50/45 and 70/40. The medium first flows through a coarse pre-filter (mesh density approx. 500 μm). This produces a filter cake that increases the degree of separation and the filter fineness. In the second step, the pre-cleaned medium passes through the fine filter, achieving a purity of up to 25 μm in the two combiloop CL3 G models, and up to 40 μm in the combiloop CL4 G-400 eco+ 70/60. The solution offers another advantage over compact belt filters. The cascading filter uses washable filter elements, including large volume ones, which greatly reduces wear and the operating costs – and is much better for the environment. Plus the productivity time of the machine is increased.

So how do all these benefits come about? It’s quite simple. Imagine the compact belt filter as a filter coffee machine. Filtration is based purely on gravity. It takes time for the medium to pass through the process. The more contaminated medium there is, or the less that flows away, the more the filter fills up with medium, and the faster the float gives the signal to continue the belt’s cycle. This in turn leads to a relatively faster consumption of the nonwoven fabric, and with that to more frequent changes. In the case of Müller’s cascading filter system, the medium is firstly pre-filtered, and secondly is literally pushed through the elements. This results in a higher availability of the pure medium thanks to the large elements. And only from a certain differential pressure, i.e., when the filter cake is too impermeable, is the signal to change given.

Automatic filtration reduces operating costs and supports unmanned operation

The entry-level option, combiloop CL4 G-400, is a basic version with which the 400-l clean liquid tank does not necessarily have to have an automatic filter, but can alternatively be used with the less expensive cascading filter. The automatic filtration is essential for the full-flow filtration versions combiloop CL4 G-600 and CL4 G-800. However, both the CL4 G-400 and the two CL3 G versions can be fitted with the self-cleaning automatic filter. Self-cleaning automatic filtration is the ultimate in CL filtration, and is the optimum solution for medium and high levels of contamination. The automatic filter enables low-maintenance, reliable and sustainable operation.

eco+ dynamic power concept saves energy for lower costs

It is generally the case that the self-regulating eco+ piston pump is geared towards the maximum energy efficiency. It provides exactly the volume flow that is actually required. Thanks to the control effect, up to 26% of energy is saved, and significantly less heat passes into the medium. This results in higher temperature stability in the medium, which leads to improved, more uniform machining. The self-regulating eco+ piston pump also has an incredibly long service life and reduces both downtime and maintenance costs.

Predefined interfaces for fast, safe use

Thanks to close system partnerships with leading machine manufacturers and 20 years of plant engineering, we have predefined and tailor-made interfaces for a wide range of machines that enable the efficient interaction between high-pressure peripherals and lathes through smooth communication between machine control and machine.

Compactness saves space for greater productivity and flexibility

The compactness, with simultaneous performance and high efficiency, results among other things from the intelligent, space-saving filtration concept as well as the pressure-controlled piston pump technology. The models combiloop CL3 G eco+ 50/45 and 70/40 measuring 1,300 x 600 x 1,100 mm (L x W x H) in particular are unrivalled in this field of application. These systems are mobile, and can also be used on a range of machines. The combiloop CL4 models, on the other hand, are stationary. However, with the clever technology built on the clean tank – and wonderful accessibility thanks to the door – the combiloop CL4 G-400 eco+ of with up to 60 l/min at 70 bar is a real space-saver..
