OFITE 172-00-C Roller Oven with Programmable Timer and Circulating Fan

Product Overview

The OFITE Roller Oven is a specialized laboratory instrument designed to simulate the effects of temperature and pressure on drilling fluids. It provides essential heating and rolling functionality for routine laboratory analysis, including chemical reaction simulation, viscosity testing, and corrosion analysis. The unit features a digital temperature controller, a seven-day programmable timer for unattended operation, and a circulating fan to ensure consistent, uniform heating.

Safety Guidelines

Important: Always wear heat-resistant gloves and eye protection when handling hot aging cells or operating the oven. The exterior of the oven can become extremely hot during operation. Ensure the unit is used in a grounded circuit with at least 8 Amps of capacity. Always turn the heat switch off before loading or unloading cells to avoid injury from the circulating fan or rotating components.

Operation and Setup

To begin, connect the oven to an appropriate power source. The programmable timer allows for automated start and stop cycles. Use the control panel to set the desired temperature and motor speed. The digital controller displays both the current temperature and the setpoint. When rolling samples, ensure O-rings are installed on the aging cells to prevent damage to the rollers.

Maintenance

Regular maintenance is required to ensure optimal performance. Apply a small amount of grease to the chains and sprockets every 90 days. Do not lubricate the Teflon roller bearings. Periodically check the door insulation; if it becomes rigid, replace it to maintain thermal efficiency. The unit is fused to protect the motor, heaters, and controller; replace fuses only with the specified ratings.

Troubleshooting and Disposal

If the temperature controller fails, a redundant thermostat will automatically cut power to the heaters at 500°F. For technical support or repairs, contact the manufacturer. Dispose of the unit and its components in accordance with local environmental regulations.
