Home/Industry Applications/Refrigeration
The ultrasonic copper tube sealing and cutting machine is the most mature application in the refrigeration industry, mainly used for:
◆ Refrigerator/Freezer:Compressor copper pipe sealing and refrigerant pipeline leak-proof sealing
◆ Air conditioning:Sealing copper tubes for evaporators and airtight welding of refrigeration circuits
◆ Wine cabinets / portable air conditioners / water dispensers / water heaters:The end of the copper tube has no open flame sealing seal
◆ Refrigeration system piping:Tail sealing, sealing, and sealing welding of copper or aluminum pipes
◆ Heat exchanger/radiator:Copper tube ends are sealed
◆ Sensor tube sealing:Copper tube sealing for capillary or spherical temperature sensors

Advantages | Explanation |
No open flame welding | No open flames are generated during welding, fundamentally eliminating the risk of fire and explosion |
Compatible with flammable refrigerants | Perfectly compatible with sealing A3/A2L flammable refrigerants such as R290, R600a, and R32 |
Efficient sealing | Soldering takes about 1 second, with cutting and sealing completed in one step |
High sealing | Breaking strength can reach over 400N (evaporator copper tube), and burst strength can reach 1500N (copper tube). |
Refrigerant leak-proof | Airtight welding ensures long-term sealing of the refrigeration circuit |
Suitable for various pipe materials | Supports copper tubes, aluminum tubes, copper alloy tubes, and more |
With the Kigali Amendment promoting the switch of refrigerants from R134a/R410A to flammable refrigerants like R290/R600a, traditional flame brazing has been gradually phased out due to the risk of open flames. The flame-free sealing solution provided by ultrasonic copper tube sealing machines has become a compliant choice and a safety necessity for new refrigerant production lines.
