APPLICATION
CJC Desorbers are used for removing water from all lubricating and hydraulic oils, both mineral and synthetic. Desorbers are particularly well suited for oil systems where water ingress is a large and continuous problem. The desorber can dry the oil down to a water content of <200ppm removing 4-6 L of water per hour. Read the case stories below

FUNCTION
The desorption process is based on the fact that heated air can absorb large quantities of water.

When oil, preheated to a temperature of 60-75^oC, is pumped through the desorber column it is met by a counterflow of air supplied by a blower. The air, heated very quickly by the hot oil, will absorb any water present in the oil.

In the closed loop system the humid outlet air passes two oil extractors before entering the condenser (an air/water heat exhanger). The now cold air enters a demister where water settles in the bottom.

Settled water is drained from the demister to an oil/water separator from which desorbed water (and oil condensed from the air) can be discharged.

The air blower draws its cold inlet air from the demister. Consequently no air from the desorption process is lead out into the open - the CJC Desorber is operated with a closed air loop.

INSTALLATION
As standard the CJC Desorber unit is supplied on a base plate or skid. Preferably it should be placed on top of the system oil tank, permitting the desorber to gravity drain directly into the tank.

The desorber works as an off-line unit, i.e. independent of the system pumps, and is supplied with a complete set of electric controls/control panel including motor overload protection, and monitoring the operation of pumps, blower, heaters, etc.

CJC Desorber units can be adapted to meet customer requirements, including features such as two-parted separate tank, level, switches and indicators, water monitors - even a mobile kit is available.
