COMPRESSORS
Compressors with WPS technology had to be tested
for 500 hrs. in intervals and as well as fatigue testing. This
means 21 days around the clock to prove if it deserves
our name. Each condenser had to manage more than
85 million condensations!
Verdict for this Marathon test series: There was no dama-
ge to the condenser or motor in any model! PLS is clearly
the condenser technology of the future.
21 DAYS AS IF NOTHING HAPPENED:
THESE ARE OUR OIL-FREE COMPRESSORS WITH PLS TECHNOLOGY:
No more oil change, oil disposal
or oil level checks
Cost saving
Generated compressed air is
oil-free and clean
Lower weight
THE ADVANTAGES OF THE PLS TECHNOLOGY:
Oil leaks no longer possible
Maintenance-free
Environmentally sound
No oil carbon formation
on the valves
30% less friction
Better cold start behaviour
5% more air output
Less process heat and reduced
development of condensation
water
Safer transport
Compressors with the maintenance-free Permanent
Lubrication System (PLS) use piston rings made of the
high-tech space material PTFE (teflon). This means that
there is no more lubrication of the compressor’s con-
denser with environmentally harmful and expensive oil.
These piston rings take on the task of the conventional
steel piston rings. There is therefore no more conventio-
nal lubrication with mineral oil that leads to reduction of
the service life.
LUBRICATED, WITHOUT OIL.
