1 Introduction
The Koehler High Temperature Convertible
Oxidation Bath is a constant temperature oil bath
with solid state temperature control, calibrated flow
meters and a condenser water manifold for
oxidation stability and corrosiveness tests on
inhibited steam turbine oils, distillate fuel oils,
mineral transformer oils, extreme-pressure fluid
lubricants, gear oils, mineral oils, inhibited mineral
oil based steam turbine oils, mineral oil based anti-
wear hydraulic oils and diesel engine oil. The
instrument is a fully customizable oxidation bath
available with a selection of Sample Racks and
Flowmeter Stands to conform to a wide range of
standard test methods including ASTM D943,
D2274, D2440, D2893, D4310, D4636, D4871,
D5968, D6594, DIN 51394, DIN 51586, DIN
51587, FTM 791-5307, FTM 791-5308
specifications, which evaluates the oxidation
characteristics of oils in the presence of oxygen
and catalysts at elevated temperatures.
This manual provides important information
regarding safety, technical reference, installation
requirements, operating condition specifications,
user facility resource requirements, and operating
instructions for the High Temperature Convertible
Oxidation Bath and Data Acquisition Software.
This manual should also be used in conjunction
with applicable published laboratory procedures.
Information on these procedures is given in
section 1.2.

Package
3.2 Unpacking
Carefully unpack and place the instrument and
accessories in a secure location. Ensure that all
parts listed on the packing list are present. Inspect
the unit and all accessories for damage. If any
damage is found, keep all packing materials and
immediately report the damage to the carrier. We
will assist you with your claim, if requested. When
submitting a claim for shipping damage, request
that the carrier inspect the shipping container and
equipment. Do not return goods to Koehler without
written authorization.
3.3 Setup
Equipment Placement. Place the instrument on a
firm, level table in an area with adequate
ventilation or in a hood. The unit may be leveled
by making minor turning adjustments to the feet
located at the base of the unit. Please note that
Koehler does not supply a level with this
equipment.
Ventilation. A fume hood or exhaust system is
required when operating the unit. Flammable
vapors and/or steam are generated during
operation and must not be permitted to
accumulate. A canopy-style hood may be used if
the height from the top of the unit to the canopy is
5 feet or less. The exhaust blower should have a
rating of 1000 C.F.M. or greater.
Power. Connect the line cords to properly fused
and grounded receptacles with the correct voltage
as indicated in section 1.3 or on the back of the
unit.
WARNING: For safety, disconnect the power
when performing any maintenance and/or
cleaning. Do NOT turn the power on unless the
bath is filled with the proper medium; otherwise,
damage may occur to the unit and the warranty
will be void.
Air Supply Requirement. This unit requires an air
source capable of supplying a flow rate of 94 or
167 mL/min per test cell depending on type of flow
meter installed. The air should be free from
moisture, oil, and particulate matter. A drying
tower should be incorporated to remove any
contaminants. Air inlet pressure should not exceed
10 psi.
NOTE: Koehler Instrument does not supply air
source required for running instrumentation.

4 Descriptions
4.1 Instrument Controls
Figure 2: Instrument Descriptions
1. Power Switch. This switch controls the power
to the entire unit. When the power switch is in
the ON position, power is supplied to the unit,
turning on the digital temperature controller.
2. Motor Switch. This switch controls turning
ON/OFF the motor for stirring the bath
medium.
3. Temperature Controller. The temperature
controller regulates the bath temperature for
the test procedure. Refer to Section 4.3 for full
operational details.
4. Flowmeter Adjustment Knob. Used to adjust
inlet flowrate during Flowmeter Calibration and
Testing Procedure.
5. Flowmeter. For indicating and monitoring of
the Oxygen flow rate during the test method.
6. Motor. Powers the stirring shaft and blade for
stirring the bath medium for bath temperature
uniformity.
7. Oxidation Test Cell Assembly. Oil Sample is
placed within oxygen test tube and is
contacted with oxygen in the presence of
water and an iron-copper catalyst at an
elevated temperature.
8. Water Outlet. Water exit location of internal
oxygen cooling manifold system. Bath
consists of eight outlet nozzles equipped with
turn valves.
9. Water Inlet. Point of connection for Water
feed for internal oxygen cooling manifold
system.
10. Air Inlet. Point of connection for Oxygen feed
to Oxidation bath. For Flowmeter Calibration,
Certified Flowmeter is to be connected to this
inlet. Flowmeter Calibration is discussed in
detail in section 5.4 of this operation manual.
