The oil temperature control unit works by heating thermal oil through electric heaters and circulating it through processing equipment to maintain a stable temperature. The heated oil flows into molds or machinery via a high-temperature-resistant pump and returns after heat exchange, forming a closed-loop system. A PID controller constantly adjusts the heating to ensure precise temperature control. Key components include a heating tank, circulation pump, PID temperature controller, expansion tank, safety valve, and cooling system. This system ensures efficient heat transfer, stable operation, and enhanced process accuracy across industrial applications.
| Heater | Heats the thermal oil to the desired temperature range. |
| Circulation Pump | Circulates hot oil through the system and connected equipment (e.g., molds). |
| Oil Tank/Reservoir | Stores the thermal oil and maintains stable volume during operation. |
| Temperature Controller | Typically a PID controller for precise temperature regulation. |
| Cooling System | Uses water or air to lower oil temperature when needed. |
| Sensors (RTD/Thermocouple) | Measure oil temperature and send data to the controller. |
| Safety Devices | Includes over-temperature alarms, pressure relief valves, and emergency stop. |
| Piping and Fittings | High-temperature-resistant connections to ensure leak-free circulation. |
| Electrical Control Panel | Houses PLC or microcontroller, relays, fuses, and user interface. |
| Air Exhaust System | Automatically or manually removes trapped air before or during operation. |

Oil and water temperature control unit are both essential for precise thermal management but differ in operating range, cost, and applications. Oil temperature control unit is designed for high-temperature processes, typically 25°C to 350°C or more, due to oil’s high boiling point and thermal stability. Oil temperature control unit is widely used in die casting, high-precision injection molding, rubber processing, and aerospace parts where consistent high heat is crucial. However, oil unit requires more energy, regular oil replacement, and higher maintenance cost. Water temperature control unit is more cost-effective, suitable for low-to-medium temperature needs up to 180°C under pressure, such as food processing, pharma, and basic molding. For high-precision or high-heat applications, oil temperature control unit justifies its cost with stable performance. For routine industrial use, water temperature control unit offers better value. Select based on temperature needs, budget, and expected return on investment.
