Directions for use
NALFLEET™ Alkalinity Control provides alkaline conditions in the boiler water for optimum control of corrosion and scale deposition and should be used as part of a multi-product treatment programme.
Dosing method
For optimum results dose NALFLEET™ Alkalinity Control direct to the boiler with an automatic dosing unit, or via the bypass pot-feeder installed in the boiler feed line.
Dosage and control
A proper level of treatment is maintained by testing for p-Alkalinity. The level is determined by the pressure and type of boiler. Refer to the dosage table below for correct dose rates. The normal method of raising the alkalinity level is by adding the required quantity of NALFLEET™ Alkalinity Control after testing for p-Alkalinity. 225 ml/ton will raise the p-Alkalinity by 100 ppm.
USING THE TABLE: Select the section corresponding to the pressure of the boiler to be treated and read across the table to obtain the level of treatment required.

Proper treatment should normally give a pH between 9.5 and 11. These are recommended values based on experience and are in no way intended to replace the boiler manufacturer's specifications or company regulations.
Sampling and testing
A representative sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blowdown, cooled and tested immediately. Follow the WSS Test Kit instructions and log the results in Waterproof. The results should be sent to WSS as stated in the Waterproof instructions.
It is important that regular testing is carried out to ensure levels of treatment are correct.

Product Number Product name
571307 ALKALINITY CONTROL 25 LTR
认证
挪威国家公共卫生研究所批准在淡水发生器中进行酸洗操作后用作中和剂
使用说明
NALFLEET™ Alkalinity Control 可在锅炉水中提供碱性条件 ，以最佳控制腐蚀和水垢沉积 ，并应作为多产品处理程序的一部分使用 。
加药方法
为获得最佳结果，NALFLEET™ Alkalinity Control 应在锅炉配备自动加液装置 ，或通过安装在锅炉给水管路中的旁路罐式进料器。
剂量和控制
以ml / ton锅炉体积计的碱度控制剂量通过测试保持适当的处理水平
对碱度 。水位由锅炉的压力和类型决定。有关正确的剂量率 ，请参阅下面的剂量表。提高碱度水平的常规方法是在测试p-碱度后添加所需量的NALFLEET™ Alkalinity Control。225毫升/吨将使p-碱度提高100ppm 。
使用表格 ：选择与待处理锅炉的压力相对应的部分，并在表格中读取以获得所需的处理水平 。

适当的治疗通常应该在pH值之间9.5和11.这些是基于经验的推荐值，绝不是为了取代锅炉制造商的规格或公司规定 。
采样和测试
应每天抽取一份代表性的锅炉水样本进行分析 。排污后应始终从同一点取样，冷却并立即进行测试。按照WSS测试套件说明进行操作 ，并将结果记录在防水中。结果应按照防水说明中的说明发送至WSS。重要的是进行定期测试以确保治疗水平正确 。
