SELCO SF-500 is a synthetic fluid designed
to meet the needs of rotary and reciprocating
industrial compressors. The product exhibits
excellent high temperature properties coupled
closely with outstanding oxidation resistance.
Currently available lubricants often compromise
on compressor requirements, for example reciprocating
units using automotive crankcase oils formulated
to MIL specifications can suffer from heavy
carbon and ash deposits on valves, SELCO products,
on the other hand, are formulated solely for
compressors.
The
advantages of SELCO SF-500 are
 |
Reduce carbon formation
and the risk of explosion, and increase
safety |
|
Virtually eliminate varnish
and sludge deposits, ensuring that items
such as oil/air separators in rotary.
Compressors function efficiently at
all times. |

|
Extend oil drainage intervals
upto 8000 hours or 12 month's operation |
|
Outstanding
operating temperatures range which will
effect operating economics in compressor
down time and lubricant utilization. |
|
Good compatibility with
elastomers used as seals in reciprocating
compressors. |
|
Reduce oil consumption
and carry over by virtue of their low
volatility and good lubrication properties |
|
Maintain the high efficiency
of reciprocating compressors by significantly
reducing valve deposits. |
|
Reduce maintenance
costs by reducing wear and deposits
associated with the use of mineral oils,
savings on replacement parts and labour
can be achieved. |
|
Improve oil
receiver and crankcase performance by
virtue of their low foaming properties. |
