10. Why IMW?
5 Exclusive Competitive Advantages

11. #1
IMW Exclusive Competitive Advantages
ONLY #1: IMW non-lubricated compressors set
the global standard for minimum oil carry-over
in CNG compressors without the waste, cost and
negative environmental issues of additional filters, auto
oil drain systems and supplementary oil tanks. Only 5
parts-per-million or less vs. 100 PPM or more.
 Lower operating costs: Oil litres/year: Lubricated
systems= up to 1200 vs. IMW = 80 in crankcase
 Lower maintenance costs: no oil accumulation in
compressor or vehicle systems. Happier customers
and increased station profitability.
 Inside a CNG vehicle, onboard CNG stored at 3600
psig is regulated to 100 psig by a regulator and then
injected into engine. There are many examples of oil
soaking the regulator diaphragm, affecting its
accuracy and, in some cases, causing a rupture of
the regulator internals if oil clogs the regulator.
“
The majority of engine performance
issues are attributable to oil carryover,
which is a problem that begins at the
fueling station.
