b. Heat exchanger: The unit's heat exchanger adopts a shell and tube heat exchanger、The internal heat exchange copper tube adopts the internally threaded copper tube type.

c. System: Adopting modular design, flexible combination, strong adaptability, up to16Unit and system protection.

d. Electrical system: The unit adopts SchneiderLGUse waterproof cabinets for electrical components of other brands.

e. Multiple refrigeration circuits and compressors design, low starting current, flexible energy regulation.

f. The single module structure is compact, small in size, and easy to transport and lift.

g. Adopting a large-diameter low-speed axial flow fan, the unit has low vibration and noise.

◇ Energy saving: The unit adopts the energy-saving program independently developed by "Shanglei" to ensure that the unit automatically adjusts the operation of the compressor according to the set working conditions, greatly ensuring smooth and energy-saving operation of the unit.

◇ Simplicity: The unit structure is simple and has a good human-machine interface. Within the operating range of the unit, the operating conditions of the unit can be freely set. Once set, the unit can operate on its own and adjust its energy in real time, making it easy to operate.

◇ Flexibility: The unit adopts modular design and manufacturing, with each module having a frame structure, refrigeration system, and protection system. Each module can operate independently or be combined and centrally linked through microcomputer modules32Single machine module online operation, especially suitable for situations with large changes in cooling area and cooling load.

◇ Each compressor refrigeration system can serve as a backup for each other.
