Particulate separators use centrifugal action to remove particulate contamination from fluids such as sand, paint flakes, metal chips, chemical scale and other debris down to 50 micron.

The well established range of particulate separators manufactured by Rosedale Products Europe has been extended to include both smaller and larger sizes and to include motorised purging as an option. Rosedale separators use centrifugal action to remove particulate contamination from fluids, either as a general clean-up facility or as a pre-filter to extend service periods in fine filtration systems. They are effective at removing sand, paint flakes, metal chips, chemical scale and other debris down to 50 micron.

The number of housing sizes in the range has been increased from seven to eleven so that Inlet and outlet connections now range from 3/8 BSP to 6in flange to accommodate nominal flow rates from 15 to 5400 litres/min.

All sizes work on exactly the same principle where contaminated fluid enters the top of the cylindrical housing at a tangent forcing solid particles outwards and downwards until they are deposited in the base tank ready for purging.

The cleaned fluid rises up a centre tube to the outlet connection at the top of the unit.

Little or no maintenance is required; there are no moving parts to wear out or fail nor filter media to replace or clean.

To dispose of accumulated contaminant, three purging methods are available.

A valve at the bottom of the unit is opened and closed manually; or the valve can be left open slightly allowing the contaminant to leak out continously at a controlled rate; or the newly available electrical valve allows purging to be carried out automatically in a timed opening and closing sequence the frequency of which is set to match the level of contamination present.

Material of manufacture is either carbon steel or stainless steel both with 10 bar pressure ratings.

Overall heights are from 452mm to 1890mm, heights of the larger units include integral support legs.

Many industries use Rosedale separators and the new sizes will allow larger applications to be considered.

Present installations in the water industry for instance, include well and river extraction, whilst industrial processes include steel mills, cooling systems, washing systems, machine tool cutting fluids, quench tanks, solids recovery, hydraulic systems and paint spray booths.
