Reduce the water content in the oil to < 100 ppm — within the shortest time
Desorber D30 from CJC®: Your solution for dewatering oils

Desorber D30 – Reduce water content in oil
Desorbers D30 from CJC® minimize the water content in the oil within a very short time – whether hydraulic oil, gear oil, lubricating oil, processing oil, leakage oil or quenching oil, and whether mineral oil or synthetic fluids. Due to the installation in a separate off-line circuit or at a free-standing tank, oil dehumidification is carried out continuously and independently of the operation of your machine. The CJC® Desorber D30 removes free, emulsified and dissolved water and reduces the water content in the oil to < 100 ppm — even oils that poorly separate water and form stable emulsions. Oil dehumidification by desorption is also ideal for oils with high viscosity and air content. It does not affect the additive package.
The CJC® D30 reduces the water content and thus protects against
After solids, water is the second most common cause of failures and malfunctions in lubricating oil and hydraulic systems. Your solution: CJC® Desorber
Areas of application & installation example — Desorber D30
The pump in the oil inlet of the desorber D30 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 from the oil (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
“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.”
