Key Features:

High-Efficiency Heat Transfer PerformanceThe unit is equipped with premium inner-grooved copper tubes and high-efficiency aluminum fins with secondary flanging. By leveraging hydraulic tube expansion technology, a tight and seamless bond is formed between the aluminum fins and copper tubes. Moreover, the copper tubes are thoroughly cleaned with trichloroethylene to eliminate all impurities, ensuring uniform frosting and exceptional heat transfer efficiency.

Superior Airtightness & Durable StructureAll coils undergo a rigorous airtightness test under 2.6MPa pressure. Prior to factory shipment, they are pressurized and filled with nitrogen to guarantee consistent quality and performance. The outer shell is finished with anti-rust coating or embossed aluminum plate spraying, delivering excellent corrosion resistance, rust prevention, and scratch resistance. This robust design enables reliable operation even in the high-humidity environment of cold storage facilities.

Fast & Effective Defrosting FunctionThe system adopts well-insulated stainless steel U-shaped electric heating tubes, configured with optimized power output and uniform spacing. With a combined total power of 3.6kW for both coil and water pan defrosting heating tubes, it achieves rapid defrosting with outstanding results. Additionally, it supports water flushing defrosting via a specialized spray structure, effectively preventing water splashing during the process.

Easy Installation & MaintenanceDesigned for ceiling mounting, the unit features channel-type hangers for hassle-free installation. Both the double-layer water pan and side panels can be flexibly disassembled without complex tools. Furthermore, all wiring is centralized in a single electrical box, significantly simplifying on-site installation procedures as well as subsequent inspection and maintenance work.

Stable & Energy-Saving OperationBrand-name motors and electric heating tubes are selected as core components, boasting stable quality, low energy consumption, and high operational efficiency. While ensuring continuous and reliable refrigeration performance, this configuration helps minimize the overall operational costs of cold storage systems.
