dynamic temperature control system for process control

Dynamic temperature control system is a high-precision fluid temperature control equipment integrating compressor refrigeration and electric heating, which is able to realize rapid, stable and programmable temperature rise and fall operation in a wide temperature range.

Description

Dynamic Temperature Control System

The dynamic temperature control system is designed to connect loads such as reactors, micro-reactors, test units, and more. It is essential for high-end process development, pharmaceutical production, new material research, and other advanced applications. With full temperature zone refrigeration, intelligent control, real-time process tracking, programmed curve control, and electronic data management, this system provides comprehensive solutions for complex temperature control needs.

Features

  1. Ultra-wide temperature control range: Covers -80°C to +200°C, meeting both deep cooling and high temperature process requirements.
  2. High-precision control capability: Temperature fluctuation less than ± 0.2°C, suitable for high stability requirements.
  3. Full temperature zone start refrigeration: Refrigeration can be started at any temperature point, with no cold zone limitation.
  4. Multi-mode refrigeration switching: Choose from continuous, automatic, or prohibited refrigeration modes according to process needs.
  5. Dual-control mechanism: Supports both “internal temperature control” (fluid temperature) and “process temperature control” (reactant temperature via external sensors).
  6. Uniform temperature function: Ensures linear and controllable temperature change, ideal for sensitive processes.
  7. Program temperature control system: Create up to 10 groups of temperature programs, each with 100 segments, supporting complex curve control.
  8. Data security and management: Logs all operations and faults; supports USB export/import, electronic signatures, and three-level authority management for GMP environments.
  9. Intelligent man-machine interface: 7-inch high-definition touch screen displays set values, actual values, alarms, and system status in real time.
  10. Multi-point safety protection: Complies with GB 4793.6 and IEC 61010-2-010; features mechanical over-temperature protection for equipment and experiment safety.

Working Principle

  1. Heat carrier circulation: Transmits heat carriers (e.g., heat transfer oil, water-ethanol mixture) in a closed loop to exchange heat with the target equipment (e.g., reactor jacket).
  2. Refrigeration: Compressor compresses refrigerant to high-temperature/high-pressure gas, which condenses, is throttled, and evaporates to absorb heat from the carrier for cooling.
  3. Heating: Electric heater quickly warms up the heat carrier, which is circulated to the controlled equipment.
  4. Control: PID temperature controller dynamically adjusts heating and cooling power based on user settings for precise temperature management.
  5. Internal control mode: Uses outlet fluid temperature as the control target.
  6. Process control mode: Uses Pt100 sensor inside the reactor to control temperature based on reactant temperature feedback.

Typical Application Areas

  1. Fine chemicals and organic synthesis: For fast, precise temperature changes and reaction control (e.g., Grignard reaction, nitrification, low-temperature coupling).
  2. Pharmaceutical process control: GMP and FDA compliant production, including API synthesis, crystallization, and temperature-controlled titration.
  3. New energy materials development: Used in electrolyte performance testing, core thermal response analysis, and superconducting materials research.
  4. Reaction kinetics and thermal analysis: Supports studies of material thermal response and reaction heat processes.
  5. Chemical amplification research: For simulation and verification of process thermal management in pilot and continuous reaction systems.
