Dailey ThermoJet Oil Purifier System Operational Checks
The following operating checks should be made daily;
a) The normal inlet Pump Discharge pressure gauge reading is between 210 to 240 PSIG (14.5 and
16.5 BAR) at operating temperature.
b) The normal Filter Discharge pressure gauge reading is between 210 to 240 PSIG (14.5 and 16.5
BAR).
c) The normal System Discharge pressure gauge reading is between 50 to 100 PSIG (3.5 and 6.9
BAR) at operating temperature depending upon size/configuration of the oil return line.
d) The temperature controller output setting gauge reading is relatively steady within 10
o
F of the
temperature controller set point on electric heated units. The normal process temperature is
between 160
o
-185
o
F.
e) Removed water vapor is exhausting.
f) Compare the Pump Discharge and Filter Discharge pressure gauges for the pressure difference
between the two readings. If the pressure drop is approaching 25 PSID (1.7 BAR), the filter
element is plugged and must be changed.
