1、双速电机 Two-speed motor
为配合节约能源及降低噪音之要求，可选择配备双速电机（通常为1500转/1000转单 绕组线圈）
Normally,two-speed motors are provided in 4p/6p single winding configuration.A considerable reduction in noise and energy management can be achieved.
2、变频控制系统及保护装置
Frequency conversion system and site electricity controller
为节约能源和日常管理之便，可选配变频控制系统，该系统通过安装在冷却塔出水口 的高效敏感温度传感器，在不同的环境，热负荷下，对中央处理器（cpu）准确地反 馈冷却塔系统负荷信号，并指引变频调节电机转速，从而达到也能目的。冷却塔配备 现场控制保护装置，实现冷却塔风机、电机的现场直接控制，对冷却塔的日常维护提 供了安全保障。
To save the energy and daily management.frequency conversion system and
site eletricity controller might be furnished.
3、特种功能散热片 Special filler
对于进水水温大于80℃的冷却塔可选用聚丙烯散热片，或金属铝或钼材料。
For high temperature operating such as waste water
treatment,PP/aluminum/molybdenum filler can withstand up to 80℃ inlet
water(special larrangement should be made for other components,please
contact us for details).
4、不锈钢配件 Stainless steel components
由于外界环境及水质等影响，为避免冷却塔结构被腐蚀，可选择采用SS304/SS316骨 架材料及紧固件，不锈钢水盘。
As an option,we can provide type ss304 steel members,bolts and nuts.
5、过滤或除垢配件 Filter and scale borer
为保持循环水的水质，冷却塔可选配过滤器及电子水处理器，达到除污，除垢，灭菌 ，消毒之功效。
To keep the water clear,the cooling tower mighe be equipped with filter
and scale borer to remove dirty and muddy,exterminate bacterium,and
sterilize.
6、底盘发热器 Basin heaters
防水发热线连配套之温度控制器可安装于底盘内，以免冷却塔在冰点情况下运行时底 盘内的水结冰。
Electric immersion heaters with thermostat and control box are available
to kep the basin water from freezing in subfreezing weather.
7、塔体颜色 Body color
冷却塔常被安装于大厦顶层，若位置比较突出，塔体可选用与大题若之颜色，协调主 体色调。
Cooling tower installed on the roof of building may be barely noticeable
from the ground;a colored cooling tower matching to building color will
make it"good look"
