Compact Filter Separator

Application :

The CJC™ PTU 15/12 Compact Filter Separator - with integrated electric motor and pump - is used for maintaining clean and dry oil such as diesel oils, hydraulic oils, gear oils and food grade oils with a specific weight lower than that of water.

The PTU 15/12 is ideal for separation of free water from oil, removal of particles and oil degradation products, in applications such as:

• Mobile Machinery
• Compact Hydraulic Systems
• Diesel Fuel

Function :

The filter pump draws oil, e.g. from a tank and pumps it through the filter insert. From the centre of the insert the oil flows down into the coalescer where water droplets will settle in the bottom of the coalescer housing (bottom chamber).

From the top of the coalescer the oil will flow back to the tank system. The water is collected in the bottom of the coalescer housing and is drained manually (standard).

Optionally a capacitive water sensor can be mounted for indicating the water level. The pressure drop across the filter insert - and consequently the contaminant absorption of the filter insert - is monitored on the pressure gauge.

The filter outlet port is placed in the filter base. The filtered oil should be returned to the tank close to the suction pipe of the main system pump. Note that the return point should be non-pressurized.

The filter pump :

The filter pump is a gear pump. The electric motor can be supplied as AC or DC motors. IP class: IP55.

Filter insert :

The CJC™ Filter Inserts consist of several discs bonded together. The material is cotton linters (cellulose).

Main dimension :

282 x 270 x 268 mm

Main material :

Aluminium

Filtration ability :

Water Removal by Separation

The CJC™ Filter Separator removes water from oil to very low levels. The efficiency of water removal depends on the oil type and temperature.

Particle Removal

All CJC™ Filter Inserts have the following filtration degree:
- 3 ?m absolute : 98.7% of all solid particles >3 ?m
- 0.8 ?m nominal : 50% of all solid particles >0.8 ?m are retained in each pass.
The dirt holding capacity is 0.75 litres of evenly distributed solids.

Degradation Products

Oxidation products, resin / sludge, and varnish are retained by the cellulose material, which will retain appr. 0.5 kg of
oil degradation products
