注意：1. 电阻器只准垂直安装，进水口在下；出水口在上。

     

 2. 电阻器每消耗1KW功率，水流量应不小于1公升/min。但降功率使用时，就其水流量而言：5KW电阻器应不低于5公升/min; 10-20KW电阻器应不低于10公升/min; 25KW电阻器应不低于15公升/min。

      3. 如果采用循环水冷系统，其出水必须经过冷却处理方可使用, 应当使用去离子水作为冷却介质。

      4. 超出上表所列技术参数，可按用户要求协议供货。

Remarks: 1.The resistor only allowed the vertical installation,water inlet,outlet in.

        2.Resistor per 1kw power consumption,water should not be less than 1liter per minute.But reduced power use,in terms of its water:5kw resistor not less than 5 liters per minute;10-20kw resistor not less than 10 liters per minute;25kw resistor not less than 15 liters per minute.

        3. If using circulating water cooling system, the water must be treated with cooling before use.

        4.Go beyond the afore cited scope,we can provide the products according to the user's requirements.
