Introduction
The Rotating Roller Oven is a specialized laboratory equipment designed to provide uniform temperature conditions and evaluate the thermal behavior and stability of laboratory fluids, particularly drilling fluids, over time.
Continuous rotation of the test cells ensures uniform heat distribution, minimizes temperature gradients, and helps prevent sedimentation during long-term testing.
The Roller Oven is designed and manufactured by PPA Company for controlled thermal aging and laboratory testing of drilling fluids.
Advantages
- Uniform temperature distribution through continuous roller rotation
- Suitable for long-term Aging Tests
- Precise temperature control with approximately ±1°C accuracy
- Supports Pressurized Aging tests up to 200 bar
- Corrosion-resistant construction suitable for drilling fluids
- Equipped with a circulation fan for improved temperature uniformity
- Built-in Over-Temperature Protection
- Programmable timer for automatic operation
Applications
- Aging Tests for drilling fluids
- Evaluation of thermal stability of drilling fluids
- Investigation of drilling fluid behavior at elevated temperatures
- Study of sedimentation and physical changes in drilling fluids
- Simulation of thermal conditions encountered during drilling operations
- Pressurized Aging experiments
Operation
Test cells containing the fluid sample are placed inside the oven and continuously rotated on the rollers. The heating system, circulation fan, and rotating mechanism work together to maintain a stable and uniform thermal environment throughout the test.
The system accommodates four cells with 350 and 500 cc capacities, with cells capable of operating at temperatures up to 160°C and internal pressures up to 200 bar.
