Product description

• Refrigeration and heating temperature control system designed for reactors and high-heat-release processes.
• Applicable to SUS reactors and double-wall reactors where temperature differentials exceed 150°C.
• Enables rapid cooling from high-temperature reactions and fast heat-up/cool-down cycles for polymerization and advanced-flow processes.

Typical application of refrigeration heating temperature control system

• Dynamic thermostatic control of high-pressure reaction kettles and double-layer glass/reactors (cold and heat sources).
• Microchannel reactor temperature control, small-scale temperature control systems, steam-feed temperature control, and low-temperature material aging tests.
• Combined chemical cold/heat source control; cooling/heating for semiconductor equipment; temperature control for vacuum chambers.

Advantages and functions of temperature control system of refrigeration

• Wide temperature capability (examples of available ranges include −80~190°C, −70~220°C, −88~170°C, −55~250°C, −30~300°C); typical model operating range −25°C~200°C.
• High precision intelligent control with feedback PID and dedicated dynamic control algorithms; PLC-based controller.
• Cooling capacity from 0.5 to 1200 kW (model dependent) to ensure production stability and repeatability.
• Multi-function alarm and safety protections; plate heat exchanger and tube-type heaters to increase heating/cooling rates.
• 7-inch or 10-inch color TFT touch-screen display with graphical temperature curves and data export (Excel).
• Magnetic drive pump to prevent seal leakage; fully closed circulation to extend thermal fluid life and avoid oil mist or vapor issues.
• Ultra-high-temperature cooling capable of direct cooling from up to 300°C without medium change or pressurization in many configurations.

Design notes
The system uses a fully closed-pipe layout and high-efficiency plate heat exchangers to minimize required heat-transfer fluid and maximize heat utilization for fast temperature changes. An expansion vessel isolates the circulating medium near ambient to reduce oxidation and moisture absorption, lowering volatility and degradation risks across the operating range.
