These Zhengzhou Greatwall ZT series Refrigerating & Heating
Instrument are designed to provide cold and heat scource for other
equipments. It can be used in many industries such as pharmacy,
chemical industry and biology.
Features of Refrigerating & Heating Instrument:
- 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
- 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
- Refrigeration heat exchanger adopts complete brazing type, whose
occupied space is small and the efficiency of heat exchanging is
- Liquid level display function can monitor the liquid level at any
time to avoid lacking of liquid.
- Multiple protection functions including high temperature cut off,
scram, timedelay, creepage, overcurrent, over heating can fully
ensure the safety in use.
- The way of condenser and pre-cooling is air-cooling, saving the
