An Oil Temperature Control Unit (Oil TCU) is an industrial device used to precisely control the temperature of thermal oil circulated within machinery or molds. It is widely applied in industries such as injection molding, die casting, rubber processing, and pharmaceuticals, where stable and high-temperature control is critical. The unit heats oil using electric heaters and circulates it through a closed loop, maintaining consistent temperature via a PID controller. Standard oil temperature control unit typically operates within a range of 45°C to 180°C, while high-temperature oil temperature control unit can range from 25°C to 400°C, making them ideal for processes requiring high thermal stability. By ensuring uniform heat distribution, oil TCUs enhance product quality, reduce cycle times, and extend equipment life, significantly improving operational efficiency and consistency in industrial manufacturing.
The history of oil temperature control unit as following:
Origin: Oil temperature control unit emerged in the mid-20th century to meet the precision heating needs of plastics and rubber molding industries.
Development: In the 1980s–1990s, PID control and safety features improved, expanding use to die casting and pharmaceutical sectors.
Advancements: With digitalization in the 2000s, touchscreen interfaces, PLC integration, and remote monitoring became standard.
Today: Modern oil temperature control unit offers eco-friendly designs, high-temperature stability (up to 400°C), and are essential in smart manufacturing and Industry 4.0 environments.
An oil temperature control unit (TCU) is crucial in industrial processes because it ensures precise and stable temperature regulation for thermal oil circulation. This stability prevents overheating, reduces thermal stress, and maintains optimal production conditions. By delivering uniform heat, oil temperature control unit improves product consistency, reduce defects, shorten cycle times, and extend equipment life. They also enhance energy efficiency and minimize downtime, offering significant cost and performance benefits across sectors like plastic molding, die casting, and chemical manufacturing.

 | How Oil Temperature Control Units WorkBasic Working PrincipleAn Oil Temperature Control Unit (TCU) operates by heating thermal oil with electric heaters and circulating it in a closed-loop system through machinery or molds. A built-in pump moves the oil, while a PID controller monitors and adjusts the temperature precisely. The system ensures uniform and stable heat transfer, essential for maintaining consistent processing conditions, improving product quality, and protecting equipment from thermal damage. |
Detailed inforamtions of Components of an Oil Temperature Control Unit by AODE as following
| Heater | Electric heaters with adjustable heating capacities (from 12kW to 240kW) are used to raise the thermal oil temperature rapidly and efficiently. |
| Oil Pump | High-power oil pumps (1.5kW–15kW) with flow rates ranging from 6.5 to 50 m³/h ensure continuous and stable oil circulation through the system. |
| Control Panel | Equipped with a PID temperature controller (±1°C accuracy), enabling precise monitoring, temperature adjustments, and process optimization. |
| Safety Devices | Multiple safety functions: inverse phase protection, oil shortage alarm, overheating protection, overload trip, oil overflow alarm, and abnormal heating detection. |
| Heat Transfer Medium | Specially formulated thermal oil, designed for stable heat conduction and high-temperature operation (up to 300°C). |
| Cooling System | Indirect cooling method using water pipes (1/2 inch standard), helping to cool the oil when necessary. |
| Expansion Tank | Provides space for thermal oil expansion (24L to 300L), protecting the system from pressure build-up. |
| Power Supply | Standard 3-phase 380V 50Hz industrial power supply, ensuring consistent operation across models. |

Temperature control units (TCUs) include oil temperature control unit and water temperature control unit, both are critical in precision temperature management for industrial processes such as injection molding, die casting, chemical reactions, and more. But water Temperature Control Unit (WTCU) and Oil Temperature Control Unit (OTCU) differ significantly in performance, application range, and operation method.
Water temperature control unit typically uses either direct or indirect cooling and is limited by the boiling point of water. The water temperature control unit is ideal for applications requiring temperature control up to 180°C and offers faster heat transfer and lower operational costs. In contrast, Oil temperature control unit operates at much higher temperatures, up to 400°C, thanks to the high boiling point and stability of thermal oil. They are widely used in high-temperature applications that require consistent heat and safety.
Each type has its own advantages and limitations based on medium, temperature range, accuracy, safety features, and cost. Below is a comprehensive table comparing the features of both systems.
