The closed high temperature circulator is a liquid circulation equipment that adopts electric heating to heat up, which can provide high temperature circulating liquid to the outside world. It is widely used in the heating of reaction kettle devices in the pharmaceutical, chemical, petrochemical and other industries.



  • The equipment has the function of over-temperature alarm protection to ensure the safety of the equipment.
  • Circulating pump can output the heat-conducting fluid inside the machine and heat the equipment outside the machine.
  • Electric heating is produced by professional manufacturers to ensure reliability and service life.
  • The equipment has an exhaust valve, which is convenient for adding liquid to the system. It is forbidden to open the exhaust valve during operation.
  • The circulation system is made of stainless steel, which is anti-corrosion, anti-rust and anti-high temperature liquid pollution.
  • This machine adopts PID control technology, with high temperature control precision, convenient operation and simple use.
  • Refrigerant circulation system adopts a closed system, which greatly improves the service life of the heat transfer oil.
  • The product is easy to use and can work continuously.
