Refrigerant Filling Equipment Performing Pipeline Evacuation for Residual Recovery

Before a refrigeration circuit is charged, it must be emptied of air and moisture, and the pipeline connecting the machine to the product must be properly prepared. Manual processes for this are slow and typically result in residual refrigerant being released to atmosphere. The HongCe HC-RF-V2 combines pipeline evacuation and residual refrigerant recovery in a single automated sequence, preparing the circuit for charging without manual intervention and preventing unnecessary refrigerant loss.

Evacuation runs as a defined step within the charging sequence with monitored vacuum levels. The process automatically stops only when the required vacuum is achieved, eliminating operator judgment and ensuring consistent results.

Instead of venting residual refrigerant from the line, the machine recovers it before releasing the charge. This recovery process maintains cleaner working areas, reduces refrigerant consumption, and helps facilities meet environmental reporting targets that customers increasingly demand.

Suitable for refrigeration and air-conditioning assembly lines, heat-pump production, and any process where circuits must be evacuated and prepared before precise refrigerant charging.

HongCe provides comprehensive support including installation, process tuning, and operator training. We can assist with recording evacuation and recovery data for internal and customer reporting. Preventive maintenance schedules and recommended spare parts are supplied with each machine.

Yes. The sequence can be configured per recipe according to the specific product and refrigerant requirements.

Recovery is integrated into the charging sequence, making the total cycle time controlled and predictable.
