Vacuum Pump(SHB-B95) + 100L Explosion-Proof Glass Reactor(GR-100EX) + Refrigerating and Heating Unit (ZT-100-200-30H, ZT-100-200-40H, ZT-100-200-80H)
Characteristics:
Can provides cold source and heat source for reaction kettle, groove and other equipments etc. It can be used in many industries such as pharmacy, chemical industry and biology.
Features:
1.It is divided into three systems:refrigerating system, heating system, pre-cooling system. Three systems can be used continuously and also can be used seperately.
2.Temperature can be increased and lowered continuously.
3.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.
5.High temperature cooling and refrigeration function can lower from high temperature level directly(e.g.: can lower temperature from 200°C directly).
6.Refrigeration heat exchanger adopts complete brazing type.
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.
