Universal-Fit Copeland Scroll Compressor Unit with Automatic Motor for Custom Cold Rooms-Eco-Friendly Cooling Solutions

Q1. What are the types of evaporators (ceiling-mounted, cold fan) and defrosting methods (electric, hot water, hot gas)?

We mainly provide ceiling-mounted cold fans and other air-cooled evaporators; we offer three defrosting methods: electric, water, and air defrost.

Q2. Do the compressor and other key components come with independent inspection reports?

Yes. All our compressors and core components are accompanied by independent inspection reports issued by the original manufacturer, ensuring that critical parts of each unit meet national performance and safety standards.

Q3. Is the complete unit subjected to full performance testing before shipment? Can you provide a test report?

Yes. Each unit undergoes powered testing before shipment, including complete verification of seven core performance indicators such as cooling capacity, energy efficiency ratio, and pressure sealing. We can provide a standardized factory inspection report containing key performance parameters (cooling capacity, input power, COp value, etc.) along with the shipment.

Q4. Do you have a strict leak detection process to ensure no leakage before the system leaves the factory?

Yes. We follow a triple leak detection standard: Component pre-inspection: All core piping components undergo precision leak testing using a helium mass spectrometer before assembly. In-process inspection: After system welding/connection, a 24-hour pressure holding test (with nitrogen at 4.2 MPa) is conducted immediately. Final inspection: After the unit is fully charged, the entire system is scanned using an electronic halogen leak detector with a precision of 0.1 g/year. Each unit comes with a "Hermeticity Inspection Report" that includes pressure-holding curves and leak detection points, ensuring that the annual refrigerant leakage rate is below the 1.5% required by ISO standards.

Q5. Is installation guidance service available? Is there any additional charge?

Yes, we provide professional installation guidance service for all products. Standard installation guidance is free of charge. We offer remote video guidance and detailed electronic installation manuals.

Q6. Is a complete packing list provided with the shipment?

Yes. Each shipment will include two copies of a detailed packing list in both Chinese and English, clearly listing: All main units and accessory part numbers and quantities List of specialized tools List of random technical documents (manuals, certificates of conformity, inspection reports etc.) The list is sealed in waterproof packaging and affixed to both the inside and outside of the main shipping container.

Q7. Can training materials (PPT, videos, manuals) be provided in electronic format?

Yes. We will provide a full set of electronic training materials free of charge via an encrypted online drive link, including: Equipment structure and principle PPT (editable format) Installation and commissioning instructional videos (MP4 format) Chinese-English operation and maintenance manuals (PDF version) All materials can be customized and modified according to customer requirements.

Q8. How does the manufacturer provide remote technical support when issues arise during installation and commissioning?

We offer a three-tiered response mechanism for remote technical support. Instant messaging guidance: Real-time problem diagnosis via WeChat/phone calls Video connection diagnosis: Engineers remotely access the site via video to guide trouble-shooting.

Q9. What is covered under warranty, and what situations are excluded from warranty coverage (e.g., man-made damage, force majeure)?

We provide the following standard warranty services: The entire unit enjoys a 1-year warranty, with core components such as compressors covered for 12 months Wear-and-tear parts.

Q10. Can you provide a clear troubleshooting manual for common fault codes?

Yes. We will provide the following complete set of troubleshooting materials: Bilingual Chinese-English quick reference manual for fault codes (including PDF electronic version) Tiered troubleshooting flowcharts: Complete procedures ranging from simple reset operations to core component inspections. Supporting fault simulation videos: 3-5 minute on-site handling demonstrations for common codes E1-E8.
