circulation heating thermostat

circulation heating thermostat with cooling function

Circulation heating thermostat has the function of rapid refrigeration and high-efficiency heating, and transports temperature control medium, such as heat-conducting oil or coolant to the external equipment through the closed-circuit circulation method to realize precise temperature control.

Description

Circulation Heating Thermostat

The circulation heating thermostat integrates refrigeration, heating, circulation pump group, and intelligent control module, with options for air-cooled or water-cooled cooling methods. It is ideal for high-precision thermal management in applications such as reaction kettle temperature control, new material testing, chip heat treatment, and industrial process temperature regulation. Stable operation from -40°C to +200°C, PID program temperature control, data export, and remote communication functions meet the needs of automated production and scientific research.

Core Features

  1. Wide-temperature operation capability: Covers -40°C to +200°C, suitable for low-temperature gel reactions and high-temperature cracking.
  2. Highly integrated modular structure: Integrates cooling, heating, circulation, and control systems in one compact, efficient unit.
  3. Flexible cooling mode: Supports air-cooled and water-cooled condenser forms; users select based on site conditions.
  4. High-definition touch screen control: 7-inch true color touch screen, intuitive operation, data curve display, and operation record function.
  5. Program temperature control ability: Supports 120 groups of temperature control programs, each with 100 temperature segments, allowing linear and gradient temperature rise and fall.
  6. Automatic protection mechanisms: Over-temperature, over-current, overload, delayed start, high-voltage protection, and more for safe operation.
  7. Remote communication and integration: RS485 interface compatible with MODBUS RTU, connectable to upper systems (DCS, SCADA) for centralized control.
  8. Expansion vessel design: Built-in expansion vessel and liquid level monitoring automatically respond to heat-carrying medium volume changes, ensuring stable circulation.
  9. Wide adaptation to heat conduction mediums: Supports water, ethanol, silicone oil, and other fluids for diverse application requirements.

System Principle

  1. Refrigeration Principle: Built-in rolling rotor hermetic compressor rapidly cools the heat-carrying body via condenser, capillary throttling, and plate evaporator. Plate heat exchanger is compact and efficient. Air-cooled type uses finned condenser; water-cooled uses coaxial heat exchanger.
  2. Heating Principle: Special flange-type electric heater for thermal oil provides high power density and fast response, ensuring uniform temperature distribution.
  3. Circulation and Expansion Mechanism: Shielded pump suitable for high/low temperatures delivers continuous medium flow. 304 stainless steel piping with insulation prevents heat loss/corrosion. Expansion vessel absorbs volume fluctuations; liquid level monitor ensures stable operation.
  4. Control Logic: PID algorithm adjusts temperature output in real time, supports temperature curve setting, fixed-value, and program control. Software supports data recording, curve display, USB export, and remote communication.

Application Areas

  1. Chemical and pharmaceutical reaction temperature control: High-precision synthesis, crystal culture, drug intermediate control.
  2. New energy materials development: Batteries, superconducting materials, carbon nanotubes thermal cycle testing.
  3. Semiconductor and electronic component testing: Rapid thermal stress testing for chips, circuit boards.
  4. Vacuum system thermal control support: Works with vacuum drying, condensation recovery, and related equipment.
  5. Aerospace simulation testing: Test component performance under changing temperature environments.
  6. University and scientific research experiments: Provides high-precision temperature control for research platforms and reliable experiments.
