circulation chiller for sample cooling and temp control

Circulation Chiller

The circulation chiller features modular design, integrating compressor refrigeration, heat carrier circulation, and intelligent control. It is widely used for precise instrument cooling, reaction kettle temperature control, laser equipment cooling, and electronic component testing.

Features

1. Triple Temperature Control Modes: Supports cooling, constant temperature, and heating modes for flexible adaptation to varying process needs.
2. High-Efficiency Compact Refrigeration: Imported hermetic piston compressor delivers low vibration, high energy efficiency, and quiet operation.
3. Micro-channel Condenser Technology: Efficient heat transfer design ensures rapid dissipation and compact equipment size.
4. Electronic & Capillary Double Throttle: Combines fast response with precise regulation for stable system operation.
5. Anti-freeze Crack Stainless Steel Evaporator: Coil structure submerged in liquid tank offers excellent thermal conductivity, safety, and durability.
6. Corrosion-Resistant Circulatory System: Pumps and pipelines use corrosion-resistant materials, suitable for various chemical and heat transfer media.
7. Real-time Liquid Level Monitoring: Visualized interface for easy replenishment and discharge operations.
8. Intelligent Touch Operation: 4.3-inch color touch screen supports temperature calibration, historical data viewing, and multi-parameter settings.
9. High-Precision Temperature Control: PID algorithm regulates the electronic expansion valve for ±0.5 °C stability.
10. Industrial Communication Interface: RS-485 port with Modbus RTU protocol for easy integration with host computers and DCS systems.

Working Principle

1. Refrigeration & Heating Mechanism: Compressor and expansion valve control cooling; heating unit raises the temperature as needed. Evaporator submerged in stainless steel tank ensures rapid coolant temperature changes.
2. Circulation & Conveyance: Brushless DC pump delivers heat carrier to external equipment (reaction vessels, analytical instruments, laser heads, etc.) with stable and clean operation.
3. Control System: Integrated PID algorithm enables real-time monitoring and adjustment; touch screen and remote communication allow user and system-level control.

Application Areas

1. Analytical instrument cooling: mass spectrometers, spectrometers, X-ray, and other devices needing strict temperature control.
2. Laboratory chemical reactions: provides heat/cold source for reaction kettles and microchannel reactors.
3. Semiconductor test systems: temperature and performance testing of chips and sensors.
4. Laser and plasma equipment: continuous cooling for lasers and plasma generators.
5. Battery/new energy materials R&D: stable temperature field for battery aging, cycle, and safety tests.
6. Industrial process cooling: chemical, paint, plastics, printing, and other industries.
7. Biomedical applications: vaccine storage, in vitro animal circulation temperature control, etc.
