PORTABLE FILTER UNITS

 

Five models are available in portable/fixed form. All are heavy duty, rugged, full flow- through filtration with wide micron range + dirt level. They can be used for oils/coolant/glycol etc. with suitable elements. Though filtration is possible in single pass, recirculation ensures complete cleaning. Vigorous circulation also removes all dirt accumulated at tank bottom (not done by ELC).

By regular use of these units, various machine oils can be kept sparkling clean, avoid disposal, also reduce consumption of original small imported filters. These can then be made of SS mesh washable 25/50 micron. This is the lowest cost, safe option w/o maintenance problems.

Typical use – once a month for 4-8 hrs per tank! Thus single unit can serve 25-50 machines.

This is the best choice for shop floor of engg. industry. Comparison is given with other types.

Target dirt level (w/o ELC) < 10 mg/lit, NAS < 7. (ELC can be used for further reduction if reqd.)

The unit can be used for aq. coolant etc. by using centrifugal pump and epoxy coated housing.

COMPARISON OF OUR PORTABLE FILTER UNIT WITH OTHER TYPES

 

  1. High speed centrifuge (Alfa Laval type) – this is strictly meant for oil-water separation.

With the limitation of 25 micron rating, high cost and power consumption, it is not at all suited for solid dirt removal. Without recirculation, dirt removal is negligible. Regular basket centrifuge with thick woven filter cloth gives better results for cutting oil reclamation, etc.

 

  1. Pump driven centrifuges are popular for engine oil cleaning with dedicated recirculation.

They are not suited for other use due to very slow dirt removal/pass and 25 micron rating.
3. Electrostatic Oil Cleaner (ELC) is capable of removing dirt down to 1 micron. But they have been pushed in the market for filtration much above 5 micron where flow-through filtration is far more efficient + economical. One dedicated ELC unit is reqd. for each power pack with 24 hr operation!

 

ASPECT OUR FILTER UNITS ELC UNITS

Moisture No problem Must be below 200 ppm
Temperature 20-70 30-40
Pressure 7 bar Atm
Dehydration Not reqd. Compulsory with elaborate process

Single pass Possible Not possible
Oil pressure transfer Possible Not possible
Use of SS mesh washable Possible Not possible
Filtration level 5-500 micron 1-5 micron, inefficient > 5µ
Dirt holding capacity High due to thru flow, pr. Very low due to parallel flow, no pr.
Consumable cost* Low due to thru flow Rs 2-5/lit High due to parallel flow Rs 10/lit with low dirt level
Power cost* Lower due to speed, time 5 kwh/kl Higher due to slow, 24 hr use.30 kwh/kl
Capital cost* Very low due to capacity Rs 1500/lpm Can serve 20-30 m/c. Very high, many units also reqd Rs 10000/lpm Can serve 1-5 m/c.
Tank Capacity 5 kl/day, multiple use Bigger units available. 100 lit/day Must be dedicated for large tanks.Not available >10 lpm, 100 L
Maintenance Little, conventional Rugged design Costly replacement of power pack Delicate unit. Special time sequence Reqd. to prevent oil recontamination

Conclusion: If pre-filtration is carried out with 5 µ paper/MG filter (built-in or independently) ELC can be utilized efficiently when very high degree of cleanliness if reqd. for high pr. hydraulics.
Our unit can remove >95% of dirt and get best performance of ELC!
Target dirt level w/o ELC- < 10 mg/lit, NAS 6-7; with extra ELC- 1 mg/lit, NAS 4-5.
(*cost estimates given depend on dirt level in oil; ELC is actually not usable for high dirt levels)
