ZT Series cooling and heating circulators which provide cold source and heat source has wide working range, and can be used in many industries such as pharmacy, chemical industry and biology. It provides cold source and heat source for reaction kettle and groove, etc and can be used in heating and cooling for other equipments.

The bath fluid is cooled down by compressor, and heated up by electrical heating, and it is transferred by circulating pump. The temperature of whole system is controlled by electronic control parts
1. Temperature control of double-layer reactor in the chemical, pharmaceutical or biological field.
2. Temperature control of stirred tank reactor.
3. Temperature control of high pressure reactor.
4. The application of the material testing.
5. Temperature control of amplification process in the field of micro reactor technology.
6. Temperature control of distillation system.
7. Simulation control of temperature changed in the process of technological.
8. Large temperature control system.
9. Small temperature control system.
10. Temperature control of semiconductor device.
11. Temperature control of thermal test platform in the process of auto.
12. Temperature control of vacuum chamber control panel and function.

1. It is divided into three systems: refrigerating system, heating system, precooling system. Three systems can be used continuously and also can be used seperately.
2. Heating and cooling quickly, and temperature can be increased and lowered continuously.
3. The temperature control range is wide, no need of changing heat-conducting medium in the whole course and the consumption of heat-conducting medium is little.
4. The complete closed circulating system is not easy for the heat transfer fluid to volatilize and oxidize at high temperature, or to absorb moisture in the air at low temperature, which can make the service life of heat transfer fluid longer.
5. High temperature cooling and refrigeration function can lower from high temperature level directly(e.g.: can lower temperature from 200°Cdirectly).
6. Refrigeration heat exchanger adopts complete brazing type, whose occupied space is small and the efficiency of heat exchanging is high.
7. Liquid level display function can monitor the liquid level at any time to avoid lacking of liquid.
8. Multiple protection functions including high temperature cut off, scram, timedelay, creepage, overcurrent, over heating can fully ensure the safety in use.
9. The way of condenser and pre-cooling is air-cooling, saving the water resources
