BW series box type condensing unit is specially developed for cold storage applications, and meets the stringent requirements of cold chain storage with professional design and core technology. Equipped with Emerson ZB/ZFI series fully enclosed scroll compressor, it achieves a double breakthrough in anti-liquid impact capability and energy efficiency with axial/radial dual flexible design. The compressor adopts Copeland patented technology, which can maintain stable operation under -35℃ deep cold conditions, and has a built-in exhaust temperature protection device to ensure long-term reliable operation.
1. Anti-corrosion and corrosion-resistant body:
The horizontal compact box body adopts galvanized steel plate surface spraying (RAL9006 silver gray), and the salt spray test is more than 1000 hours, which is suitable for outdoor high humidity and high corrosion environment
2. Convenient maintenance:
The chassis cover adopts a hinged quick-opening structure, with a single-side opening angle of 135°, and the maintenance space is increased by 40% compared with the traditional design
3. Structural design:
It adopts a compact box structure, and the shell is a galvanized steel plate surface spraying treatment, which has excellent anti-corrosion performance and is suitable for outdoor installation. The unit integrates core components such as compressor, condenser, and fan. When installing, you only need to connect the pipeline and power supply, which saves time and effort. For example, some models use 6-pole low-speed fans and dual fan design, which can effectively reduce noise and improve operational reliability.
4. Refrigeration technology:
The main unit can be equipped with Copeland ZB/ZFI series fully enclosed scroll compressors, which have the advantages of high efficiency, low noise, and strong resistance to liquid impact. Some models support a variety of refrigerants (such as R134a, R404A, R507A, etc.) to meet the needs of different temperature zones. For example, medium and high temperature units can meet - 5℃ ~ 5℃ working conditions, and low temperature units can achieve deep cooling applications below - 20℃ through jet enthalpy increase technology.
5. Application scenarios:
Food cold chain: -18℃ freezer daily power consumption is 15% lower than traditional units, a 3000㎡ cold storage saves more than 60,000 yuan in electricity bills per year
Medical warehousing: ±0.5℃ constant temperature control accuracy, meeting GSP certification standards
Mobile refrigeration: unit thickness ≤800mm, can be integrated into a 12m refrigerated truck, refrigeration capacity attenuation rate <5%
