The OFITE Roller Oven (U.S. Patent No. 4,677,843) is an effective aid in de-
termining the effects of temperature and pressure on drilling uid as it circu-
lates through the well bore. Aging the drilling uid in pressurized containers
effectively demonstrates the thermal effects on drilling uids in which a base
exchange reaction occurs and in determining the stability of mud additives
and emulsied uids such as oil muds. Aging is done under conditions that
vary from static to dynamic and from ambient to highly elevated temperatures.
Many mud constituents degrade slowly at high temperatures. Such degrada-
tion occurs while circulating, but it is more severe when the mud is left in the
lower part of the hole when making a trip. When running laboratory tests,
aging temperatures are often selected to be near the anticipated circulating or
bottom-hole temperatures and pressures, and aging cells are typically rolled
in an oven for at least 16 hours.
Routine laboratory analysis using roller ovens would include:
a. Simulate chemical reactions taking place in freshly prepared muds.
b. Determine the time it takes reactions to reach equilibrium under tem-
perature and pressure.
c. Determine the Viscosity of the uid prior to aging and after.
d. Determine ltration control properties prior to aging and after.
e. Determine the stability of drilling uid additives and drilling uids such
as oil muds.
f. Perform corrosion analysis.
The 4-roller oven can hold six 260-mL Aging Cells or three 500-mL Aging
Cells, while the 5-roller oven can hold twelve 260-mL Aging Cells or eight
500-mL Aging Cells. These are both ideal for laboratory use. OFITE rollers
are variable-speed controlled and constructed of stainless steel for longer life
and a cleaner environment inside the oven. Glass-impregnated Teon®roller
bearings extend the life of the rollers and allow for longer maintenance-free
service.
All models feature a digital temperature controller that can be read directly
from outside the oven. The temperature is controlled by an electronic solid-
state thermostat and operates between 100°F and 450°F (38°C - 232.2°C).
The 4 and 5-roller ovens include a seven-day programmable timer as stan-
dard equipment. The timer may be preset to automatically start and stop the
heaters, allowing unattended operation. A circulating fan is included on all
models which greatly improves air circulation within the oven providing more
stable, consistent, and reliable uniform heating.
The Redundant Heat Control is available on select models and is a safety
feature for the heaters in the event one or more over-heat. Power to the
heaters will be shut down if the oven temperature exceeds a set maximum
temperature. The aging process due to the length of time required for com-
pletion of the test, is seldom monitored, so a heater failure may be serious.

Always wear heat resistant gloves and other suitable protection whenever
working with hot roller ovens and Aging Cells.
a. Installing Aging Cells inside a hot oven.
b. Removing Aging Cells from a hot oven.
Always wear eye protection when working with Roller Ovens. Be careful to
not open a hot oven with your face directly in front of the newly opened door.
During operation the outside of the Roller Oven can get very hot, especially the
door area, and may cause burns if carelessly touched by unwary personnel.
The circulating fan inside the oven can be very dangerous if adding or remov-
ing Aging Cells when the blades are turning. To prevent injury always turn
the “Heat” switch on the Control Panel “Off” when loading or unloading cells.
OFITE ships all Roller Ovens with a covered back to protect against get-
ting clothing caught in the rotating chains and sprockets. This cover should
remain in place at all times except when working on the chains or sprockets.
For ovens where the rear cover is missing or has been misplaced, then the
back of the oven should face closely to a wall.
Disconnect all power cords when performing maintenance or replacing a fuse.
Be careful when working around the latch on the door, especially the knob and
latch. Fingers can get caught in the latch resulting in a painful injury.
The corners of the oven may cause injury if impacted directly. Be especially
careful when working around the top stainless steel motor housing as sharp
corners may cause cuts during cleaning.
Ovens should always be used in a ground circuit.
Make sure the electrical source has at least 8 Amps of capacity.
Aging Cells can be very dangerous if handled improperly. Elevated tempera-
ture and pressure within the cell can cause the contents to be released with
explosive force.
Always allow the cell to cool to ambient temperature before opening.
Always point the cell away from people and equipment when depressurizing
by opening the valve stems.
Do not overll the cell. Refer to the instruction manual for Aging Cells #175-
25, #175-30, #175-50 to determine the appropriate uid volume for the test
conditions.
Periodically check the inside of Aging Cells for stress or pit corrosion. Oper-
ating cells in high or low pH concentrations or with concentrated saline solu-
tions (Chlorides) will promote corrosion.

Quick Start 1. Plug in to appropriate electrical outlet.
2. Flip the “Heat” switch on the control panel ON. The red light pulsates
when temperature is reached. This also turns on the circulating fan.
3. Flip the “Motor” switch on the control panel ON. The white light comes on
and the rollers begin turning.
Programmable Timer
To set the correct local time:
1. Turn the “Heat” switch on the control panel to the ON position.
2. Set the “Out 1 switch - On-Auto-Off” to the AUTO (middle) position.
3. Set the “P1, P2, Run” button to P1 to activate programming mode for
Output 1.
4. Open the panel door and press and hold the “TIME ADJ” button until a
blinking clock appears.
5. Press the “h” and “min” buttons to set the correct local time.
6. Press “WRITE” when nished.
7. Set the “P1, P2, Run” button to P1 to show the time.
To program the timer:
1. Turn the “Heat” switch on the control panel to the ON position.
2. Set the “OUT1” switch - On-Auto-Off” to AUTO setting. Leave the
“OUT2” switch off.
3. Set the switch to the right of the display to P1 to activate programming
mode for Output 1.
4. Select the day of the week for each the ON/off operation, marked by
the removal of a dash above the day of the week button.
5. Press the “h” and “min” buttons to set the correct time for the “ON” or
beginning cycle to begin. The “UP” arrow will blink.
6. Press “Write” to activate the Turn Off time (The Down Arrow Blinks).
7. Select the day of the week for each the on/OFF operation, marked by
the removal of a dash above the day of the week button.
8. Press the “h” and “min” buttons to set the correct time for the “OFF”
cycle to end. The “DOWN” arrow will blink.

9. Press “WRITE” when nished.
10. Set the switch (“P1, P2, Run”) to the right of the display to “RUN”.
The bar (-) will display the day(s) of operation.
To clear all programmed settings:
Open the bottom panel and insert a pointed object into the “RESET” hole.
Then press and hold the “+1h / CLEAR” button for 3 seconds.
Temperature Controller
1. Upper Temperature is the current temperature.
2. Lower Temperature is the temperature set point.

Setup 1. Flip both switches on the control panel (“Motor” and “Heat”) to the “Off”
position (down).
2. Connect the power cord to the proper voltage source. If an adapter or
another power plug is required, note that the green wire is the ground
and the white and black wires are the power leads.
3. When the power cord is connected, the timer will be activated. It is rec-
ommended that the power be left connected even when tests are not
being conducted so the timer will continue to keep time.
