                         Zhengzhou Greatwall ZT-20-200-40 refrigeration unit 

I Brief introduction of the ZT refrigeration unit :

ZT series refrigeration unit which provides 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. 

We have many types for choice,temperature range from -80 degree to 200 degree.,-20 to 200 degree ,-40 to 200 degree ,the volume from 20L to 100L ,you can make a choice according to your need.

They are designed for 20L 50L 100L glass reactor.

IV Main Characteristics of refrigeration unit :

 

 

 

♦It is divided into three systems: refrigerating system, heating system, precooling system. Three systems can be used continuously and also can be used seperately.

 

 

 

♦ Heating and cooling quickly, and temperature can be increased and lowered continuously.

 

 

 

♦ 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.

 

 

 

♦ 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.

 

 

 

♦ High temperature cooling and refrigeration function can lower from high temperature level directly(e.g.: can lower temperature from 200°Cdirectly).

 

 

 

♦ Multiple protection functions including high temperature cut off, scram, timedelay, creepage, overcurrent, over heating can fully ensure the safety in use.

 

♦ Refrigeration heat exchanger adopts complete brazing type, whose occupied space is small and the efficiency of heat exchanging is high.

 

 

 

♦ Liquid level display function can monitor the liquid level at any time to avoid lacking of liquid.

 

 

 

 

♦ The way of condenser and pre-cooling is air-cooling, saving the water resources
