Key Features:

Efficient heat transfer performance: It adopts high - quality inner grooved copper tubes and high - efficiency aluminum fins with secondary flanging. Through hydraulic tube expansion technology, the aluminum fins and copper tubes are closely combined. And the copper tubes are cleaned with trichloroethylene without impurities, which ensures uniform frosting and high heat transfer efficiency.
Reliable airtightness and durable structure: Its coils undergo an airtightness test at 2.6MPa and are pressurized and filled with nitrogen before leaving the factory to ensure stable quality. The shell is treated with anti - rust painting or embossed aluminum plate spraying, featuring corrosion resistance, rust prevention and scratch resistance, and can adapt to the humid environment of cold storage.
Effective and rapid defrosting: It adopts well - insulated stainless steel U - shaped tubular electric heating tubes with reasonable power and uniform spacing. The total power of the coil and water pan defrosting heating tubes is 3.6kW, which realizes short defrosting time and good effect. It also supports water flushing defrosting with a special spray design to prevent splashing.
Convenient installation and maintenance: It is designed with channel - shaped hangers for ceiling installation. The double - layer water pan and side panels can be flexibly disassembled. In addition, all wires are concentrated in one electrical box, greatly facilitating on - site installation and later inspection and maintenance.
Stable and energy - saving operation: It selects brand - name motors and electric heating tubes. These components have stable quality, low energy consumption and high efficiency during operation, which helps reduce the overall operation cost of cold storage while ensuring continuous and stable refrigeration.
