Instructions for use of high and low temperature cooling water circulation device

When the temperature of the reactor, reactor, rotary evaporator, extraction equipment and other devices equipped with the high and low temperature cooling water circulation device needs to be raised or lowered rapidly, the device can quickly make it reach the set temperature
.

1.
What is the working principle of the high and low temperature cooling water circulation device? The high and low temperature cooling water circulation device adopts the compressor refrigeration method, which can directly cool test tubes, reaction bottles, etc.
for low-temperature chemical reactions, and conduct low-temperature storage of chemicals and biological products.
It can also be combined with a rotary evaporator , glass reactor, vacuum drying box, multi-purpose vacuum pump for circulating water, etc.
, and are also widely used in low temperature tests
.

2.
Instructions for use of high and low temperature cooling water circulation device: 1.
For the first use, the inlet and outlet valves should be installed on the inlet
.

Note: The liquid inlet and outlet are marked on the top of the machine, the valve is a stop valve, the valve medium flows in a direction, the valve is marked with the flow direction, and the oil level gauge observation window
.

2.
Connect the valve and the external circulation equipment such as the reaction kettle with hoses.
The inlet and outlet of the reaction kettle should be bottom-in and top-out, and the medium in the reaction kettle should be kept in a proper position
.

3.
Open the filling hole of the high and low temperature coolant circulation pump, add the refrigerant into the cold tank, turn on the circulation switch of the machine, and let the liquid circulate in the whole system
.

(Note: the air in the system should be evacuated) 4.
The cooling medium configured by the original factory can meet the conditions of use
.

5.
If the temperature of 130°C is required, set the temperature control table to 130°C, turn on the heating switch and the cycle switch, and the machine starts to work
.

6.
When the material needs to be lowered to room temperature at high temperature, it is necessary to turn off the heating and turn on pre-cooling.
At this time, the material can be lowered to room temperature by cooling
.

Wuxi Guanya high and low temperature cooling water circulation device is a special device for accurate temperature control in the chemical and pharmaceutical industry, which is used to meet the temperature control of batch reactors or the heating and cooling and constant temperature systems of continuous process
