Mixed Gas Refrigerant Top-Up Service
We offer a special top up service for Polycold®, VplusM, Hannam, Samsung and Rihai CP cryo generators. All brands of cryo- generators may be refilled to restore original performance.
Does not contain any HCFCs and be used in any cryo-generator.
Field Service:
We are all over the world and can usually arrive at your factory within a few days, if you are in our local area, you can arrive within 24 hours.
1. If refrigerant leaks, check for leaks and repair them;
Refrigerant leakage will cause the cooling capacity to decrease, the cooling speed will be slow, and in severe cases, a low-pressure alarm will occur and the machine cannot be started. Polycold refrigerant leakage is a common failure of this equipment when dealing with this failure.
Generally follow the following principles when dealing with refrigerant leaks:
When checking for leaks, it is easy first and then difficult, first outside then inside;
After the leakage point is dealt with, the pressure needs to be maintained for a long time to ensure that there is no leakage before proceeding to the next step;
After filling the refrigerant, the equipment operating data needs to be recorded and archived for subsequent review;
2. System maintenance
After Polycold has been running for a long time (usually two years), the system pipelines will become more or less contaminated. In severe cases, it will lead to unstable operation of the equipment and a decrease in refrigeration efficiency.
Maintenance of Polycold is to ensure that Polycold is in good operating condition and provide controllable guarantee for production.
The main tasks of Polycold's major maintenance are to clean the system pipelines, replace the compressor refrigeration oil, and deal with minor faults that occur in daily operation;
3. Compressor failure
There are two main types of compressor failures, one is the motor part and the other is the mechanical part. The main faults in the motor part are that the motor coil is open, short-circuited or grounded. The mechanical part often has internal air leakage and excessive vibration.
If the compressor fails, the only option is to replace the compressor (because the repaired compressor is even more insecure);
4. The system is dirty and blocked.
It is difficult to determine the cause of a dirty and clogged system, such as refrigerant deterioration, compressor wear, or leftovers from related operations.
The faults described are for reference only. Specific equipment faults need to be comprehensively analyzed with reference to Polycold fault phenomena and historical records.
In order to ensure the reliable operation and controllability of your company's equipment, please conduct necessary inspections on your Polycold and establish equipment files.
5. Spare parts
Our company stocks various Polycold accessories: Polycold standard refrigerants, low-temperature solenoid valves, low-temperature joint gaskets, insulation materials and refrigeration oil, as well as Polycold compressors.
After Polycold has been repaired by our company, if the Polycold hardware is normal, the operating state is usually close to normal operating state. Free warranty is provided after repair. In addition, after our company repairs Polycold, our company will create detailed equipment files for future reference.
In order to ensure the normal production of customers, our company has brand-new Polycold and can perform exchange maintenance according to customer requirements, that is, replace the faulty equipment and return it to the factory for repair, and replace it with a spare machine to ensure that customers can produce normally.
