Taizhou Muli Environmental Protection Technology Co.,LTD

We are Evaporative Air Cooler Manufacturer in China.

A. Feature of the frequency inverter for air cooler

The variable frequency control system with separation main board and operation panel.

It has the characteristics of separation machine and key board , remote operation , dust and moisture resistance (IP65).

Through RS485 communication function , the main board can detect the water level status automatically . By controlling the water inlet valve and water pumping to make the water flow between each wet curtain in the machine ,   large area contact with the air so as to evaporate and   heat dissipation. By controlling the speed of the fan to control the blowing rate to send the cooled and humidified air into the room , so as to reduce the indoor temperature ,enhance the indoor air circulation , replace with the fresh air .This system adopts frequency conversion technology, can save energy and electricity and control the blowing rate, so as to realize the function of air supply and exhaust

1. Output Frequency :0HZ-50HZ   or 0HZ-60HZ (0-60HZ should be noted).

2. Type:1.5KW-220V,2.2KW-220V

3. Achieve the cooling air supply, inversion of convulsions.

4. Control the position of the leaf to achieve the different wind   directions.

5. Control the drainage of motor, to achieve the cleaning function .

6. Built-in   Infrared controller to achieve Remote control Within 20 meters.

7. Add in temperature and humidity sensor can achieve PID algorithm, so as to control the blowing rate and pump running automatically by temperature setting .   

8. With the protection function for low voltage, over voltage, over current, over heat,

overload output short circuit .

9. Use re-settable fuse, no need to change fuse frequently, so as to reduce the failure rate.
