Desorber-Filter-Unit D10

CJC® Desorber Filter Units D10 reduce the water content in your oil to < 100 ppm within a very short time. It removes free, emulsified and dissolved water from the oil. At the same time, the integrated fine filter minimizes the content of particles and oil degradation products (acids, varnish, sludge). Ideal for hydraulic oils, gear oils and lubricating oils, whether based on mineral oil or as synthetic fluids. Even stable emulsions with a water content of up to 70% can be dried and processed. Thanks to the installation in a separate circuit in the bypass flow or on a free-standing tank, oil drying and fine filtration are carried out continuously and independently of the operation of the machine. Oil drying by desorption is also independent of viscosity, additives and air content in the oil.

How to benefit from installing a CJC® Desorber Filter Unit D10 on your machine

  • You remove free, emulsified and dissolved water as well as particles and oil degradation products

  • You prevent oil degradation and loss of additives as well as acids and microorganisms

  • You provide maximum protection against corrosion, cavitation and wear

  • You extend the service life of oil and system components by a factor of 3 to 4

  • You minimize unplanned downtime and ensure higher productivity and process stability

Keeping oils and fluids as clean and dry as possible is the be-all and end-all for reliably functioning machines and smooth processes.

Application areas & installation example Desorber-Filter-Unit D10

Especially in the paper, steel, plastics and metal processing industries, as well as in maritime applications, there is a high risk of water entry into the oil systems due to environmental and process conditions.

Fine filter system:
The pump in the oil inlet sucks in the oil. In the first stage, the fluid flow passes through the filter with the integrated fine and depth filter cartridge before it is fed into the desorber chamber in the second stage. Water but also particles in the oil accelerate the degradation of base oil and additives (oil ageing). The filter removes particles and already by oil degradation processes formed reaction products.

In the desorber chamber, the still moist, warm oil meets a counterflow of cold, dry air. The oil heats the cold air, which allows it to absorb a lot of moisture (system pressure constantly low < 2 bar). In a subsequent process, the warm, moist air cools down again, and the water condenses.

That say our customers

Hydrostatische Systeme

“I am completely satisfied with the investment. Oil drying takes place very quickly and without machine downtime. Thus, we keep the production stable, have time to look for the failure cause, avoid the oil change and waste oil disposal, and maintain the oil quality.”

Head of Maintenance, Liebherr Components

The Desorber works excellently in this application. I was impressed by the results and surprised how efficiently the Desorber dewatered the oil. The Desorber is easy to operate and is low-maintenance.”

The CJC® Desorber allows us to operate the tug boat until the regular inspection in the dry dock in 6 months. The oil analysis results speak for themselves and substantiate the efficiency of the Desorber.

“It was only with the Desorber that the gear oil could finally be dried satisfactorily. Without CJC®, we would have had to change the 1,500 litres of gear oil soon. By avoiding the oil change, we were able to save EUR 4,890 (EUR 3.26/litre) – an important contribution not only in terms of budget but also in terms of resource savings. The excellent results convinced us, so we decided to purchase two identical Desorbers for our tug boats, “Bugsier 5” and “Bugsier 6”.
