Preparatory work and operation process for refrigeration and heating temperature control system

The cooling and heating temperature control system is mainly used for the heating and cooling of the reactor, and the constant temperature control.
So, what preparations should be made before the cooling and heating temperature control system is used? How to set the temperature? How is the operation process? Preparation before use of Wuxi Guanya Refrigeration and Heating Temperature Control System 1.
To use the refrigeration and heating temperature control system, open the wooden box and install the inlet and outlet valves on the liquid inlet
.

2.
Connect the valve and the reaction kettle with a hose, the inlet and outlet of the reaction kettle should be bottom in and top out, to ensure that the reactor remains full of liquid
.

3.
Open the liquid filling hole of the high and low temperature tank, add the medium into the machine and open the cycle switch of the machine
.

4.
The cooling medium should meet the conditions of use, that is, it does not freeze under low temperature conditions and does not boil under high temperature conditions
.

Wuxi Guanya Refrigeration and Heating Temperature Control System Operation Process 1.
Turn on the power and press the key, the window display enters the working state, the upper window of the display window displays the measured temperature, and the lower window displays the current set temperature
.

　　2.
Press the set button, the upper window displays 5P, and the lower window displays the set temperature with the addition and subtraction of the set temperature with △▽
.

　　3.
Press the heating button, the indicator light next to the heating button is on, and the heating starts to work
.

　　4.
Press the cooling button, the indicator light next to the cooling button is on, and the cooling compressor starts to work
.

　　Wuxi Guanya Refrigeration and Heating Temperature Control System Setting Temperature 1.
If the temperature of 150°C is required, set the temperature control meter to 150°C, turn on the heating switch and the circulation switch, and the cooling and heating temperature control system starts to work
.

　　2.
When the material needs to be lowered to room temperature at high temperature, it is necessary to turn off the heating and turn on the pre-cooling.
At this time, the material can be lowered to room temperature by cooling
.

　　3.
When the material needs to be lower than the room temperature, the material should be lowered to room temperature first, and then set to the required equipment, turn on the refrigeration, the compressor will enter the working state, and the machine will start to cool down
