EC fan: (optional)
EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds. The motor runs on a DC voltage, but with a single phase 230VAC or three phase 400VAC supply. The motor incorporates voltage transformation within the motor. The non-rotating part of the motor (stator) is extended to make room for an electronic PCB board which includes power transformation AC to DC, as well as the controls.
EC风机：(选件)
EC代表电子换向，它结合了交流和直流电压，使两全其美。电动机透过直流电压运行，而电源端可为单相230VAC或三相400VAC。电压转换在马达电机内完成。电动机（定子非旋转部分）的延伸以腾出空间给一个电子PCB板，包括电力变换AC到DC，及控制电路。
Advantages of EC technology:
- Very high degree of efficiency
- Integrated controller (continuous control)
- Very simple connection
- Additional functions (pressure control, etc.)
- Smaller-sized motor for the same level of performance
- Less power consumption
EC技术的优势：
- 非常高的效率程度
- 集成控制器（连续控制）
- 很简单的连接
- 附加功能（压力控制等）
- 相同的性能水平下使用较小尺寸的电动机
- 耗电量少
Below figure is showed the result of power consumption versus operating time for EC fan and non EC fan.
下图为EC风机与非EC风机运行耗电量比较。
Structure（机组结构）:
The case is welded by using the heart shape that has the impact resistance. The steel shell after molding is modified by the electrostatic spray treatment. This procedure makes the shell bright, clean, and nice. The steel shell is anti-carved, fireproof, anti-corrosive, and anti-rust. Furthermore, the steel shell also isolates the noise.
机组外壳使用心型焊接方式，此方式抗冲击性强，外壳使用优质钢板成型后，以静电喷塑处理外壳，表面效果亮丽光洁且美观大方，并具有防刮、阻燃、防腐及防绣等特点，隔绝机组内部噪音，密封效果好。
Protection function (保护功能）:
The unit is implemented some functions for protections, such as: motor overloaded protection, short circuit protection, over current protection, phase sequence protection, over heating protection, high pressure protection, low voltage protection, discharge temperature protection, started frequently protection, blower fault protection, air pressure fault protection, and humidified fault protection. These features are ensured that the unit is under normal operation. The unit also reserves the interface for the fire alarm system. When fire occurs, the system will send the warning signal to the control system. The system receives the warning signal and then shuts down the unit to protect the facility. The unit also provides the interface module (RS-232/RS-485) and software for options.
机组具有电机过载、短路、过电流、相序保护、加热超温保护、压缩机高低压保护、压缩机排气高温保护、压缩机频繁启动保护、送风机故障保护、风压故障保护、加湿器故障保护等功能，为确保机组正常运行，机组留有火警信号接口与消防系统连接，当发生火灾时，消防系统传送火警信号给控制系统之后，机组即进入停机状态。机组还提供了接口模块（RS-232／RS-485）和软件选项。
