Overview
GREATWALL ZT-20-200-80H 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 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 realizes precise temperature control through the joint work of pre-cooling system, refrigeration system and heating system. A fully closed circulation system is used, and the heat transfer fluid is in the domestic circulation of the system. Efficient heat exchange is carried out through the refrigeration heat exchanger (full brazed plate heat exchanger), so as to achieve the purpose of rapid heating or chilling down the target 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
