Expert advice is also recommended for installation of
other forms of mechanical anchors. See Figure 2 for
additional details.
Epoxy based grouting is required to firmly seat and
attach the booster skid to the concrete foundation.

grout is recommended. Sealing of grouts and
concrete is recommended to prevent contamination
by oil and moisture. Newly poured concrete must be
fully hydrated prior to grouting. The concrete slab
should be chipped to remove all latent and 50% of
the aggregate exposed to provide a rough bonding
surface for the epoxy. Dowels should be installed on
new exposed concrete to prevent edge lifting. The
concrete foundation should be dry and free of oil before
pouring grout. Sleeve all foundation bolts to prevent
adhesion and allow bolt stretch. Steel baseplates
should be sanded and cleaned to provide adequate
adhesion surface.
Steel fabricated foundations are generally not
recommended, but if necessary must be adequately
engineered to support the weight and vibration of the
booster.
SUCTION PIPING & FILTRATION
Booster life can be substantially increased by providing
clean, dry, cool gas to the booster suction. See Parts
Manual for general connection locations.
The suction piping must be rated for the working
pressure of the suction gas and protected with
a properly sized safety valve set at 10% (30 PSI
minimum) above the maximum operating pressure but
below the maximum allowable working pressure of the
pipe. All piping must have adequate piping support.
A suction filter must be placed in-line with the booster
inlet, to ensure clean nitrogen to the booster. The
filter should be a 1.0 micron or better, coalescing type,
sufficiently sized for twice the full flow of the booster
with minimal pressure drop. Suction filters must be
installed upstream of the suction receiver to prevent
pulsation damage. The suction receiver and piping
must be cleaned of any foreign residue before booster
startup. Unless otherwise indicated, nitrogen boosters
do NOT come with an suction gas filter. Damage to the
machine will occur if contamination is drawn into the
booster and will void the warranty! Do NOT use pipe
dope or excessive thread tape as these may damage
the booster.
Boosters are not designed to pump any liquids. Liquids
are non-compressible and even the slightest amount
of liquid can cause high-impact stresses resulting in
serious damage to the booster. The use of a liquid
trap in the suction line is required where the presence
of entrained liquids in the suction gas is a possibility.
Flexible expansion joints must be placed within 36”
of the booster to help compensate for expansion/
contraction of the pipes, as well as isolate the vibration
of the booster from the rigid piping. All piping must be
adequately supported to ensure no piping loads are
placed upon the booster. Failure to do so may cause
a dangerous break in rigid pipe caused by vibration
in the piping.
DISCHARGE PIPING
Recommended practice is to have a booster aftercooler,
discharge safety valve, discharge check valve, and a
receiver. To prevent undesirable pressure drops in
piping, pipe size should be increased one size for each
100 feet of run.
It is extremely important that a properly sized safety
valve, set at 10% (30 PSI minimum) above the
maximum operating pressure but below the maximum
allowable working pressure of the system components,
be placed at the discharge receiver and upstream of the
aftercooler. Never place a line valve in the discharge
piping between the booster discharge and the safety
valve.
A discharge check valve must be installed in the
discharge receiver to prevent high pressure nitrogen
from leaking back through the booster to the suction
side of the system, causing dangerously high pressures
in the suction side receivers, piping, etc. A separate
check valve is required for each unit if the system has
more than one booster.
On initial start-up of the booster, bubble test all piping
connections for leaks with a soap-water solution. All
piping must be leak free.
All piping must be compatible with nitrogen and must
be rated above the pressure safety valve setpoint.
