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 to benefit from your CJC® Desorber Filter Unit D40CU

  • You remove all impurities from the oil in one process — water, particles and oxidation residues

  • You rejuvenate the oil and prevent the additive loss, acids and the spread of microorganisms

  • You ensure maximum corrosion and wear protection for all oil-lubricated machine components

  • You extend the service life of oil and machine components by 3 to 4 times

  • You reduce unplanned downtime and maintenance costs while protecting environment and resources

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 D40CU

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.

Installation, Desorber-Filter-Unit D40CU, oil recovery

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.

Desorber:
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 recovery takes place very quickly and without plant downtime. Thus, we maintain production, have time to look for the error, save ourselves the oil change and 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.”
