Table 6 — Oil Separators
2.4 Oil Level Safety Switch
An oil level safety switch must be installed in the sump of
the oil separator or the oil reservoir, depending on the
system design. Carlyle recommends an oil level safety
switch that interrupts compressor operation if oil levels
are below adequate levels. Enough oil should remain in
the sump when the switch is opened for the compressor
to operate for at
least one minute before completely run-
ning out of oil.
To reduce the possibility of false oil level alarms, Carlyle
recommends that the oil level safety switch should be
open continuously for 5 seconds prior to initiating com-
pressor shutdown.
2.5 Oil Filter
Provisions should be made to isolate the oil filter using
some combination of shutoff valves and/or check valves.
This will allow for the filt
er element to be replaced without
removing or isolating the charge in the unit.
Because of the long bearing life requirements, filtration
for this compressor is very stringent. The Beta Ratio for
this filter is greater than or equal to 200 for a five micron
particle size evaluated using ISO 16889 (
(5)
200).
Filter areas must also be sufficient to avoid premature
clogging of the filter during
normal operation. The Carlyle
supplied filters have a filtration area of > 5000 cm
2
. An
alarm in the controls should be signaled any time the
pressure drop across the filter (P
DISCHARGE
– P
OIL
)
exceeds 2 bar (29 psid) indicating the filter needs to be
replaced.
