产品描述
综合型锅炉水处理剂（液体） AUTOTREAT
产品属类：655 产品编号 ：698720（25LTR）
产品说明
Autotreat 是一种液态的锅炉用水处理剂，由碱性化合物 、抗锈抗腐剂 ，挥发性胺类冷凝剂系统以及污泥调理剂复配而成。
添加方式：
最好添加Autotreat 的方式，是用WILHELMSEN 锅炉水管理系统进行连续投料 ，或者使用WILHELMSEN 锅炉水处理投料装置。
取样和试验：
每天应取样水化验一次。样水应取自相同的地点，且于排放后 ，冷却后立即试验。
依照Spectrapak试验箱的指示 ，同时记录于WHLHELMSEN所提供的记录簿上。此记录应尽速交到WHLHELMSEN负责的地点来校阅及评论。
此例行的试验不可中断，以确保炉水的正常水准是很重要的。
优点 、功能及应用
●用于简化投料和处理的锅炉水处理剂 。
●防锈防腐 ，提高系统使用寿命和可靠性 。
●含有挥发性胺类以中和冷凝系统中出现的酸性物质 。
●保持锅炉管道表面清洁 ，促进最好的热传导条件 。
●具消散性 ，可使淤泥颗粒悬浮水中 ，借排放而排出 。
●进行简单检测即可确定处理水平 。
附加消息 ：

NALFLEET™ AUTOTREAT™ is a multifunctional, liquid boiler water treatment, formulated with alkaline compounds, scale inhibitor, dispersant, and volatile amines for the protection of the feed, boiler and condensate systems.
Product information
Autotreat combines well-known phosphate treatment with new polymer technology. This ensures that precipitates are kept soft and non-adherent for easy removal by blowdown.
Features
- Liquid boiler water treatment chemical for simplified dosing and handling
- Suitable for all boilers, up to 30 bar pressure
- Contains volatile amines to neutralise acids occurring in condensate system
- Dispersant action suspends sludge and sediment particles for efficient removal by blowdown
- Keeps boiler tube surfaces clean, promoting the best heat transfer conditions
- Simple testing to determine treatment level
Benefits
- Multifunctional boiler water treatment
- Prevents scaling and corrosion, increasing system life and reliability

Directions for use
NALFLEET™ Autotreat is a boiler water conditioner designed for optimum protection of ships boiler systems when used in conjunction with an oxygen scavenger. The product combines well known phosphate treatment with new polymer technology. This ensures that precipitates are kept soft and nonadherent for easy removal by blowdown. The product should always be used in conjunction with an oxygen scavenger, preferably NALFLEET™ Oxygen Scavenger Plus. Note that this product is formulated for use in conjunction with good quality feed water.
Dosing method
The product should preferably be dosed continuously with an automatic dosing unit. Alternatively the product can be fed into the feed line by means of a by-pass pot feeder.
Dosage and control
Initial fill dosage is 2.4 litres of NALFLEET™ Autotreat/ton of boiler capacity to reach a P-Alkalinity level of approx. 200 ppm. For an untreated system it is recommended to initially bring the treatment up to a suitable level of 200 ppm p-Alkalinity. The dosage chart given below is for convenience to determine the amount of product required to elevate P-Alkalinity. Note that the table is based on reaching 200 ppm.

Blow Down |
These are recommended values based on experience, and are in no way intended to replace the boiler manufacturers specifications, or company regulations. Typical control limits are: * P-Alkalinity: 150-300 ppm as CaCO3. * Chlorides: 200 ppm Cl max. * Condensate pH 8.3-9.0. Excessive Chlorides are removed by blowdown.
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 that treatment levels are correct.
