Overview
GREATWALL ZT-50-200-80H 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 Kettle, tank 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 integrates the pre-cooling system, refrigeration system and heating system to form a fully enclosed circulation loop. The system drives the heat transfer fluid to circulate in the loop and flow through the controlled temperature equipment (such as Reaction Kettle) for heat exchange. Through precise control of refrigeration or Heating power, the temperature of the controlled equipment can be quickly raised and stabilized.
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 Appearance of the equipment and whether the connecting pipeline is in good condition.
2. Select Air-Cooled or Water-Cooled pre-cooling mode according to your needs (if optional).
3. Fill the system with the appropriate heat transfer fluid and ensure that the liquid level is sufficient through the liquid level display function.
4. Connect the power supply (3~ 380V, 50Hz).
5. Set the target temperature (range -80 ° C to 200 ° C) and control parameters.
6. Start the equipment, and the system will automatically run refrigeration, heating or combined mode for temperature control.
7. By observing the operating status and parameters of the equipment, ensure that the temperature is stable at the set value (Fluctuation +/- 0.5 ° C).
8. After use, turn off the device according to the procedures.
Notice
• Before use, please confirm that the Power supply voltage (3~, 380V, 50Hz) meets the requirements.
• Ensure that the thermal fluid level in the circulation system is sufficient to avoid dry operation.
When the equipment is running, do not touch high or low temperature parts to prevent burns or frostbite.
• Regularly check whether the protection function (such as over-temperature, leakage, overcurrent protection) is effective.
• Device weight is large (465kg), handling and installation need to ensure stability.
• Do not use outside the specified Temperature range (-80 ℃~ 200 ℃) or under environmental conditions.
• During maintenance, please be operated by professionals.
