High-pressure system combiloop CL4G-600
A STANDARD - HIGHLY CUSTOMISABLE UP TO 150 L/MIN. AT A MAXIMUM OF UP TO 300 BAR
Do you need high rinsing performance? Do you also have fine chips and a high level of contamination on the machine? Is the highest surface quality your standard? Then the combiloop CL4 G is a must. The CL4 G-600 offers you a clean tank with a capacity of 600 litres in the comfort range, which contributes to a stable behaviour of the medium and a more uniform temperature environment. The standard version features full-flow filtration and, thanks to its clever modularity, can be perfectly customised to meet your requirements in terms of process-reliable filtration, rinsing performance and cooling. In the full expansion stage, for example with an integrated active cooler up to 7.5 kW, pressure control and up to three freely combinable high, medium and low pressure pumps, it is in the top class in terms of space utilisation and performance. And not to forget: it also looks good!
Already in multiple use worldwide on machine tools from the following manufacturers:

Function and description of the combiloop CL4 G-600 high-pressure system |
The combiloop CL4 G-600 is a high-pressure system that can be used for a wide range of applications. Mounted on a clean tank with a capacity of 600 litres, the pump systems can work as a full-flow filtration system in combination with the best possible filtration system. The system is completely enclosed in a modern, metallic design to protect it from dirt and external influences. A maximum of three supply pumps, consisting of a high-pressure and low-pressure pump, are installed. A pressure-regulated pump is used to generate high pressure. It supplies the consumable tools in the machine with exactly the volume flow that they require at the preset working pressure for the respective machining operation. This enables efficient energy utilisation and avoids additional heat generation (eco+). The desired working pressure is infinitely adjustable. The cooling lubricant is delivered to the consumers in a targeted manner via direct or switchable high-pressure outlets. The cooling lubricant is drawn from the machine tank by a dirt-resistant filter feed pump and fed into the clean tank via a self-cleaning automatic filter. The filter is cleaned automatically via the measured differential pressure. The dirt collects in the integrated sludge box with filter basket, which must be cleaned occasionally by the operator. This cleaning process can be carried out during the ongoing production process without having to stop the machine. A liquid cooler specially developed for this system cools down the cooling lubricant depending on the technical possibilities and ambient temperature in order to keep the temperature stable. A factory cold water connection is not required. A return pump transports the medium from the sludge box back into the machine tank. Thanks to the electrical control system, the system can be operated autonomously. Components of the device
