GDZT-20-200-80 Fully Sealed Refrigeration and Heating Cycle Machine

The high and low temperature circulation device is a circulation device that can provide cold and heat sources. It has a wide working range and is used in industries such as pharmaceuticals, chemicals, and biology to provide heat and cold sources for reaction vessels, reaction tanks, etc. It can also be used for heating and cooling other equipment.
GDZT-20-200-80 Fully Sealed Refrigeration and Heating Cycle MachinePerformance characteristics:
1. There are three systems: refrigeration system, heating system, and pre cooling system. The three systems can be used continuously or separately.
2. Fast heating and cooling, capable of continuous temperature rise and fall.
3. Wide temperature control range, no need to replace the thermal medium throughout the process, and low consumption of thermal medium.
4. A fully enclosed circulation system ensures that the heat transfer fluid is not easily volatile or oxidized at high temperatures, and is less likely to absorb moisture from the air at low temperatures, which can extend the service life of the heat transfer fluid.
5. High temperature cooling and refrigeration function, which can directly reduce temperature from high temperature (such as from 200 ℃).
6. The refrigeration heat exchanger adopts a fully brazed plate heat exchanger, which occupies a small space and has high heat transfer efficiency.
7. Liquid level display function, monitoring the liquid level at any time to avoid liquid shortage.
8. Multiple protection functions such as high temperature cut-off, emergency stop, delay, leakage, overcurrent, and overheating fully ensure safe use.
9. The condensation and pre cooling methods are air cooling, which saves water resources.
Functional advantages:
1. Intelligent temperature control.
2. Good temperature control stability.
3. Fast heating and cooling speed, capable of continuous temperature rise and fall.
4. Fully enclosed circulation system, extending the service life of thermal oil.
5. Using a magnetic driven pump, zero leakage is achieved throughout the entire temperature range.
6. Wide temperature range.
7. Fault alarm function.
8. It has functions of delay, overheating, and overcurrent protection.
9. Liquid level display function, tracking and monitoring the liquid level inside the expansion tank.
Control advantages:
1. The fuzzy operation and PID active calculation functions have high temperature control accuracy, which can reach ± 0.5 ℃.
2. It has a reservation function and can set the automatic running time of the device.
3. There is a standby function (temperature control) that can accurately control the effective time of the experiment.
4. Two control methods (fixed value/program).
5. It can display the temperature change curve of the combined load of the closed refrigeration and heating cycle device.
6. Programming: 50 sets of programs can be programmed, with each set consisting of up to 100 segments.
7. Communication interface.
