System pressure display The pressure of the refrigeration system and circulation system is detected by pressure sensors and displayed on the touch screen.
Controller Siemens S7-1200PLC, fuzzy PID control algorithm, with process dynamic control algorithm
Temperature control Heat transfer medium outlet temperature control mode
External temperature sensor: (PT100 or 4-20mA or communication setting)
Control mode (process dynamic control algorithm)
Programmable 25 programs can be knitted, each program can be edited with 85 steps
Communication Protocol Ethernet interface TCP/IP protocol, RS485 interface MODBUS protocol
Internal temperature feedback Equipment heat transfer medium outlet temperature, medium inlet temperature, refrigeration system condensation temperature, ambient temperature, compressor suction temperature, cooling water temperature (for water cooling equipment)
External temperature feedback PT100 or 4~20mA or communication setting
Cascade control The temperature difference between the thermal oil outlet temperature and the external temperature sensor can be set and controlled
Temperature difference control function The temperature difference between the equipment inlet temperature and the outlet temperature can be set and controlled (to protect system safety)
Closed circulation system The entire system is a fully enclosed system. There will be no oil mist at high temperatures and no absorption of moisture in the air at low temperatures. The system will not increase pressure due to high temperatures during operation, and will automatically replenish heat transfer media at low temperatures.
Heating Refers to the maximum heating output power of the system (depending on the model)
The heater has triple protection and independent temperature limiter to ensure the safety of the heating system
Use a voltage regulator to control the heating output and reduce the heater output current in process temperature control
Cooling It refers to the ability to take away heat at different temperatures (under ideal conditions). The actual working conditions need to consider the heat dissipation of the environment. Please enlarge it appropriately and take insulation measures.

Working Principle

Ultra high temperature cooling technology can directly cool from a high temperature of 300℃[because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of – 80℃ ~ 190℃, – 70℃ ~ 220℃, – 88℃ ~ 170℃, – 55℃ ~ 250℃ and – 30℃ ~ 300℃ can be realized without pressurization.

Application: Various Reactors (Microchannels, Glass, Jacketed Reactors, etc.), Distillation or Extraction System, Laboratory, University, Research Institute, Aerospace, Automotive Industry, Semiconductor and Electrical Test, Chemical, Pharmaceutical, Petrochemical, Biochemical, Medical, Hospital, R&D Workshop, Aerospace, Biological and Other Industries.
