300℃ High Precision Oil Circulation Constant Temperature Machine-LEOT-30-40KW

300℃ High Precision Oil Circulation Constant Temperature Machine-LEOT-30-40KW

300°C High-Temperature Oil Circulation Temperature Controller (also known as high-temperature oil heater or oil-type mold temperature controller) is an industrial temperature control equipment that uses thermal oil as the heat transfer medium to achieve closed-loop temperature control up to 300°C. It is mainly used to provide a precise and stable high-temperature heat source for molds, reactors, rollers and other equipment, with a temperature control accuracy of PID ±1°C.

Hot Oil Temperature Control Unit

LEOT Series Oil Temperature Control Unit

 

A built-in high-temperature circulating pump drives thermal oil to circulate in a closed pipeline. The heating tube heats the oil to the set temperature and delivers it to the controlled equipment (e.g., mold/reactor). After releasing heat, the oil flows back to the host. The system monitors the return oil temperature in real time, automatically compensates for heating or activates indirect cooling, forming closed-loop constant temperature control.

 

Oil Temperature Control Unit Working Principle

The machine consists of heating system, high-temperature circulating pump, heat exchange pipeline, temperature control system and safety protection system. The thermal oil is heated by electric heating tube, then forced to deliver to the heated equipment by circulating pump, and flows back to the main unit after heat exchange and cooling for reheating circulation. The control system collects oil temperature and return oil temperature in real time, automatically adjusts heating power to realize closed-loop constant temperature control; indirect cooling function is optional.

  • The heating tubes are made of stainless steel, featuring rapid temperature rise and anti-aging properties;
  • The circulation pumps ensure efficient flow of thermal oil in closed pipelines, realizing uniform heat transfer and avoiding local temperature differences;
  • The temperature control system supports PID intelligent adjustment, with a temperature control accuracy of ±1℃, meeting the requirements of high-precision production scenarios.
Key Features
  • High-Temperature Stability: Temperature control range ambient +45°C to 300°C, achieving high temperature under low pressure for safety and reliability.
  • Precise Control: PID intelligent adjustment with accuracy of ±1°C and minimal temperature fluctuation.
  • Efficiency & Durability: 304 stainless steel piping/heating tubes, high-temperature resistant circulating pump, low energy consumption and long service life.
  • Comprehensive Safety: Protection against dry burning, over-temperature, oil shortage, overload, pump reversal and pressure relief; explosion-proof version available.
  • Smart Operation: PLC/microcomputer control, touch panel, RS485 remote communication, automatic air exhaust on startup, delayed cooling on shutdown (optional).
 

Typical Applications

 
  • Chemical industry: Temperature control for reactor/polymerization reactor/distillation tower jackets.
  • Plastics industry: Injection/die-casting molds, extrusion rollers, sheet/film production lines.
  • Composites: Carbon fiber, resin-based hot pressing, autoclave temperature control.
  • Rubber/leather: Calendering rolls, vulcanizing machines, setting equipment
 
In addition, some models support intelligent remote monitoring and data recording functions, which facilitate enterprises to grasp the operating status of the device in real time, optimize production processes, and reduce operation and maintenance costs. It is a key temperature control device for improving efficiency and ensuring product quality in modern industrial production.
 

Safety Protection Function

The oil temperature control unit is equipped with multiple built-in safety protection mechanisms, including over-temperature alarm, oil shortage protection, abnormal pressure protection, and overload protection. These mechanisms effectively prevent risks such as dry burning of the device and pipeline leakage, ensuring production safety.
