Product Description:
This model of pressure reducer is a single-stage reaction type CO₂Pressure reducer, equipped with a pressure gauge, a flow meter, and a heating device. When the pressure reducer is correctly installed on the gas cylinder valve, the power is turned on, and the gas cylinder valve is opened, the imported high-pressure gas enters the low-pressure chamber through the throttle gap of the valve and valve seat, and is transported to the user through the flow control valve. When the power supply is heated to a certain temperature by the heater, the heater will automatically adjust. When the regulated pressure exceeds a certain allowable value, the safety valve will automatically open to release air, and when the pressure drops to the allowable value, it will automatically close again.
Electric thermal carbon dioxide pressure reducer products are used for beverages, beer, and carbon dioxide protectionweldingIn situations where stable output of carbon dioxide gas is achieved; internally equipped withelectric heatingTemperature control, overheating protection and other devices can complete, control, display, regulate and other tasks, effectively preventing the freezing phenomenon caused by the large amount of heat absorbed by carbon dioxide during diffusion, thereby ensuringpressure reducerStable job.

Tips:
1.Why do carbon dioxide pressure reducers need to be heated
Due to CO2 gas being stored in high-pressure liquid form, it absorbs a large amount of heat during depressurization vaporization, which may cause the body of the meter to cool down and the water vapor inside the chamber to freeze, thereby damaging the sealing ring of the meter and shortening the product life! By using a heated CO2 pressure reducer, the temperature inside the chamber can be increased using electric heating energy, thereby avoiding the freezing of water vapor inside the chamber, eliminating the adverse consequences caused by this, and extending the service life of the pressure reducing valve.
2.why36VMost commonly used:
Generally speaking, there is a 36V power supply directly on the carbon dioxide protection welding machine, so that the 36V pressure reducer can be plugged in and used without the need for an external power supply. Of course, due to special requirements, a few welding machines provide a 110V power supply, which requires a 110V voltage regulator. There are also 220V voltage reducers available, which can be directly plugged into 220V AC power for use.

Safe use and maintenance：
1. When installing the pressure reducer, check that the specifications connected to the gas cylinder valve are consistent, and open the gas cylinder valve when warm. After blowing out the garbage, connect the pressure reducer to prevent impurities from entering the pressure reducer.
When opening the bottle valve, avoid standing on the front and outlet of the pressure reducer, and slowly open it to avoid accidents.
3. The pressure reducer should be properly stored to avoid impact and vibration, and should not be placed in places with corrosive media.
4. The heater power supply is divided into three types of inputs: 220V, 110V, and 36V, and should be connected according to the markings.
5. If the pressure regulator is damaged, it should be repaired by professional technicians or directly contacted by the manufacturer.
