A STANDARD - HIGHLY CUSTOMISABLE UP TO 60 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 CL4G is a must. Even the entry-level CL4G-400 offers a clean tank with a capacity of 400 litres, which contributes to the stable behaviour of the medium and a more uniform temperature environment. It offers high-pressure, bypass or full-flow filtration and, thanks to its clever modularity, can be perfectly customised to your requirements in terms of process-reliable filtration, rinsing performance and cooling. When fully equipped with an integrated active cooler up to 5.5 kW, pressure control, a high-pressure and a low-pressure pump and bypass filtration, it is a real space saver. And not to forget: it also looks good!

Already in multiple use worldwide on machine tools from the following manufacturers:
Benzinger, Biglia, Brother, Bumotec (Starrag), Chiron, Citizen, DMGMORI, Fanuc, Hermle, Index, Kitamura, Manurhin, Mazak, Nakamura, Okuma, Pfiffner, Schütte, Star, Tornos, Traub, Tsugami, Willemin-Macodel, and many more.

FUNCTION

Function and description of the combiloop CL4 G-400 high-pressure system

The combiloop CL4 G-400 is a high-pressure system that can be used in a variety of ways. Mounted on a clean tank with a capacity of 400 litres, the pump systems, in combination with the best possible filtration, can operate either as a pure high-pressure system, as a bypass system or as a full-flow filtration system. To protect against dirt and external influences, the system is completely enclosed in a modern, metallic design.
A maximum of two supply pumps are installed, consisting of a high-pressure pump and a low-pressure pump. 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 channelled directly to the consumers via direct or switchable high-pressure outlets.

Standard with cascade filter:
Cooling lubricant is drawn from the machine tank by means of a dirt-resistant filter feed pump and fed into the system's clean tank via a cascade filter. The filter cascade has two stages and consists of a pre-filter of maximum 500 µm and a post-filter as a fine filter of maximum 40 µm. 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. Thanks to the electrical control system, the system can be operated autonomously.

Option with automatic filter:
In this version, 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. Using the predefined pressure levels option, specific pressures adapted to the machining process can be called up via the machine programme.
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. Thanks to the electrical control system, the unit can be operated autonomously.
