Proactive Corrosion Resistant Energy-Saving Motor-Driven Condensing Unit for Restaurant Walk-In Coolers Commercial Freezers 1

Q1. What are the types ofevaporators (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 inspectionreports?

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

Q3. ls the complete unit subjected to full performance testing before shipment?

Canyou provide a test report?Yes. Each unit undergoes powered testing before shipment, including complete verifcationof seven core performance indicators such as cooling capacity, energy efciency ratio, andpressure sealing. We can provide a standardized factory inspection report containing keyperformance 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 thesystem leaves the factory?

Yes. We follow a triple leak detection standard:Component pre-inspection: All core piping components undergo precision leak testingusing 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 elec.tronic halogen leak detector with a precision of 0.1 g/year.Each unit comes with a "HermeticityInspection Report" that includes pressure-holdingcurves and leak detection points, ensuring that the annual refrigerant leakage rate is belowthe 1.5% required bylSO standards.

Q5.ls installation quidance service available? ls there any additional charge?

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

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

Yes. Each shipment will include two copies of a detailed packing list in both Chinese andEnglish,clearly listing:All main units and accessory part numbers and quantitiesList of specialized toolsList of random technical documents (manuals, certifcates of confommity, inspection reportsetc.)The list is sealed in waterproof packaging and affxed to both the inside and outside of themain 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 encryptedonline 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 modifed according to customer requirements.

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

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

Q9. 保修范围包括哪些内容,哪些情况不包括在保修范围内(例如,人为损坏,不可抗力)?

我们提供以下标准保修服务:整个装置享有1年的保修期,核心部件如压缩机享有12个月的磨损件保修.

Q10. 您能提供一份针对常见故障代码的清晰故障排除手册吗?

是的.我们将提供以下完整的故障排除材料: 中英文双语故障代码快速参考手册(包括PDF电子版) 分层故障排除流程图:从简单的重置操作到核心组件检查的完整程序. 支持故障模拟视频:针对常见代码E1-E8的3-5分钟现场处理演示.
