Operate your machines only with clean and dry lubricant
Desorber-Filter-Unit D5 from CJC®: Your solution for fine filtration and drying of oils
Desorber-Filter-Unit D5
CJC® Desorber-Filter-Units D5 dry your oils and fluids in the shortest possible time and reduce the water content to less than 0.01 %. They specifically remove emulsified and dissolved water, while the integrated depth filter reliably retains particles and oil ageing products (acids, varnish, sludge). Ideal for hydraulic and lubricating oil systems as well as gearboxes – regardless of whether mineral oil or synthetic fluid is used. Even oils with a water content of up to 70 % and low water separation capacity can be dried and processed effectively. By installing it in a separate bypass circuit or on a free-standing tank, the Desorber Filter Unit D5 maintains your oil continuously and independently of machine operation. Drying is based on the principle of desorption – highly efficient, independent of viscosity and air content in the oil and without any influence on additives.
How you benefit from installing a CJC® D5
- Ensure permanent oil quality — for trouble-free operation
- Reduce component replacement and oil changes
- Minimize maintenance costs and protect resources
- Avoid unplanned downtime and stabilize processes
- Increase system availability and operational reliability
- Reduce operating costs and increase productivity
After solids, water is the second most common cause of failures and malfunctions in lubricating oil and hydraulic systems. Your solution: CJC® Desorber
Application areas & installation example — Desorber-Filter-Unit D5
Desorber:
The pump in the oil inlet sucks in the oil. In the desorber chamber, the warm, moist 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, and the water condenses again.
Fine filter system:
After the desorption process, the fluid flow passes through the filter with the integrated fine and depth filter insert. Water but also particles in the oil accelerate the degradation of base oil and additives. The filter removes both particles and already formed reaction products (acids, sludge, varnish).

That say our customers
“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.”
“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”.
“The Desorber is ideal for such operations because it works continuously while the vessel is at sea. The results are very satisfactory. The Desorber works very well and will further reduce the water content.”
