Overview
GREATWALL ZT-20-200-30H closed refrigeration heating cycle device is a circulation device that can provide heat or cold sources. Its wide working interval can be used in chemical, biological and other industries to provide heat and cold sources for Reaction Kettles, tanks and other equipment.
Features
1. Wide temperature control range: -80 ° C to 200 ° C.
2. Pre-cooling system, refrigeration system and heating system can be used in combination.
3. Quick heating or chilling down.
4. The cooling rate is large, allowing for rapid cooling.
5. Fully closed circulation system, the heat transfer fluid is not easy to volatilize and oxidation at high temperature; it is not easily affected by environmental conditions at low temperature, which can prolong the service life of the heat transfer fluid.
6. The refrigeration heat exchanger uses a fully brazed plate heat exchanger, which takes up little space and has high heat exchange efficiency.
7. Liquid level display function, real-time monitoring of liquid level, to avoid the lack of heat transfer fluid.
8. Over-temperature protection, leakage protection, over-current protection, and other protective functions ensure the safety of users and equipment.
9. According to user requests, two pre-cooling models, Air-Cooled and Water-Cooled, can be provided.
Principle
The device achieves precise temperature control through the joint work of the pre-cooling system, the refrigeration system and the heating system. The system adopts a fully enclosed cycle, and the heat transfer fluid flows through the refrigeration heat exchanger or heating device for heat exchange under the drive of the circulation pump, thus providing a stable cold or heat source for external equipment.
Applications
Temperature control of double-decked and three-layer Reaction Kettle in chemical and biological fields, temperature control in material testing, temperature control of distillation system, temperature change simulation control in process, thermostatic Control system, temperature control of semiconductor equipment, temperature control of thermal test platform, temperature control of vacuum chamber
Steps
1. Check the device connection and power supply.
2. Select the Air-Cooled or Water-Cooled pre-cooling method according to your needs.
3. Set the target temperature and control parameters.
4. Start the equipment and observe the liquid level display and operating status.
5. During equipment operation, monitor temperature fluctuations and protection function status.
6. After use, shut down according to the specified procedures.
Notice
• Power supply voltage meets requirements (220-240V~, 50Hz) before use.
• Pay attention to real-time monitoring of the liquid level display to ensure sufficient heat transfer fluid.
Equipment has a variety of protective functions, but it still needs to comply with safety regulations when operating.
• Choose the appropriate pre-cooling method (Air-Cooled or Water-Cooled) according to the actual application requirements.
• Do not exceed the specified Temperature range (-30~ 200 ℃).
