OIL FOR SINGLE SCREW
COMPRESSORS
Due to the need for adequate lubrication, Vilter rec-
ommends only the use of Vilter lubricants, designed
specifically for Vilter compressors. With the extensive
research that has been performed, we are able to of-
fer specific lubricating oils. Use of oil not specified or
supplied by Vilter will void the compressor warranty.
Installation
TESTING SYSTEM
FOR LEAKS
Vilter equipment is tested for leaks at the factory.
One the most important steps in putting the system
into operation is field testing for leaks. This must
be done to assure a tight system that will operate
without any appreciable loss of gas.
First, if test pressures exceed the settings of the
system, relief valves or safety devices, they must
be removed and the connection plugged during the
test. Secondly, all valves should be opened except
those leading to the atmosphere. Then, open all
solenoids and pressure regulators by the manual
lifting stems. All bypass arrangements must also
be opened.
HYDROCARBON SYSTEMS
“Oil pumped” dry nitrogen, or anhydrous CO
2
in
this order of preference may be used to raise the
pressure to the proper level for testing.
When the proper pressure is attained, test for leaks
with the soap mixture previously described. After
all leaks are found and marked, relieve the system
pressure and repair the leaks. Never attempt to
repair soldered or welded joints while the system is
under pressure. Soldered joints should be opened
and re soldered.
Do not simply add more solder to the leaking
joint. After all the joints have been repaired and the
system is considered “tight”.
Remove the drum and bring the pressure to the rec-
ommended test level with oil pumped dry nitrogen
or CO
2
. Then check the entire system again for leaks,
using a halide torch or electronic leak detector.
Be sure to check all flanged, welded, screwed and
soldered joints, all gasketed joints, and all parting
lines on castings. If any leaks are found, they must
be repaired and rechecked before the system can be
considered tight again, remembering that no repair
should be made to welded or soldered joins while
the system is under pressure.
