Features of small laboratory high and low temperature cycle cooling and heating machine

The liquid circulation of the whole system of the small laboratory high and low temperature cycle cold and heat integrated machine is airtight, and the system has an expansion vessel.
The expansion vessel and the liquid circulation system are adiabatic, and do not participate in the liquid circulation, but are only mechanically connected, regardless of the temperature of the circulating liquid.
However, the medium in the expansion vessel is always kept at room temperature
.


1.
The small laboratory high and low temperature circulation cooling and heating machine has no internal circulation tank.
The internal circulation volume is small, the effective power density is large, the heating and cooling rates are fast, and the demand for heat transfer oil is relatively small
.

The equipment adopts wave-shaped plate heat exchanger, which has large heat exchange area and fast heat exchange speed
.

2.
The entire liquid circulation is closed, and the heat transfer oil will not be oxidized or browned; it will not absorb the water vapor in the air at low temperature, which prolongs the life of the heat transfer oil and reduces the use cost
.

3.
Accurate control of the temperature of chemical reactions is the choice for reliable control of exothermic reactions
.

　　4.
The equipment adopts PID intelligent control, which automatically adjusts the output of power according to the chemical process technology, accurately controls the temperature of the reaction process, and meets the requirements of the reaction process for temperature changes
.

　　5.
The specially customized circulating pump can provide large flow rate, generate small pressure and heat, achieve high heat exchange efficiency, small system resistance, pump system heat and system energy consumption
.

　　6.
Adopt PLC control, more user-friendly display interface (man-machine interface), easy to operate, can display the set temperature, outlet temperature, temperature change curve in the kettle body during the working process, and realize multi-stage temperature programming of the program
.

　　7.
The temperature difference between the kettle body and the jacket can be set according to the reliable requirements provided by the reactor manufacturer.
If the temperature difference between the inside and outside reaches the reliable value required by the manufacturer, Wuxi Guanya equipment will automatically stop working and prompt to ensure the reaction.
The kettle will not rupture due to excessive temperature difference
.

The small laboratory high and low temperature cycle cooling and heating integrated machine can provide heat transfer oil with a wide range of working temperatures, so the same machine and the same heat transfer medium can achieve continuous temperature control
