Water-cooled packing
cases are required for
compressor cylinders
based upon the average
piston speed and aver-
age cylinder pressure.
Cooled packing cases
are supplied to help
remove heat generated
as the piston rod/packing
friction increases with the
higher pressures and
piston speed.
Cooled packing cases
are required for cylin-
ders in accordance with
Figure 4-8.

1. All cylinders that have water-
cooled packing as standard (see
Ariel Performance Program) must
be connected to a water cooling
system, unless prior approval is
obtained from Ariel Technical Ser-
vices.
2. If a separate lube supply is
needed due to the gas analysis
(H

S, CO

, water saturation, air,
etc.) an additional increase in vis-
cosity may be needed if the cooling
connection to a water cooled p
acking case is ommitted. Contact Ariel Technical Services for
assistance.
3. Cooling water quality and treatment is to be maintained to prevent corrosion and mineral
or other deposits. Cooling water must be treated with an appropriate anti-freeze, such as
glycol, if subject to freezing.
