Minimize water content, particle content and oxidation levels — in one process
Desorber-Filter-Unit D30CU from CJC®: Your solution for the separation of oil-water emulsions and oil recovery
Desorber-Filter-Unit D40CU
The D40CU desorber filter unit quickly and efficiently reduces the water content in your oils and fluids to < 0.01% while minimizing the content of particles and oxidation products (acids, sludge, varnish). Whether hydraulic oil, transmission oil, lubricating oil, machining oil, leakage oil or hardening oil, and whether mineral oil or synthetic fluid, the D40CU desorber filter unit separates even stable oil-water emulsions with a water content of 70% and enables the complete recovery of oils and lubricants. Installed in an independent bypass stream or on a freestanding tank, the D40CU dewaters and cleans the oil (24/7). Dewatering during oil recovery is carried out by desorption. Ideal even for highly viscous oils and airborne oils. Desorption does not affect the additive package.
How you benefit from installing a CJC® D40CU
- Greater process reliability thanks to fewer unplanned downtimes
- Higher machine reliability – investment sustainably protected
- Longer oil service life and component service life
- Less maintenance and cleaning work
- Lower operating costs and higher output
- ReducedCO2 footprint for greater sustainability
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 D40CU
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.”
