Specification

Directions for use

NALFLEET™ 2000 has been designed for use in all common types of engine cooling water systems. Nalfleet 2000 will protect ferrous metals, copper and copper alloys and all other metals including aluminium components. NALFLEET™ 2000 will not affect rubber gaskets or other non-metallic components within the cooling system.

For general guidance where aluminium is present:

No aluminium present - Use Engine Water Treatment 9-108 or Rocor NB Liquid

<10% Aluminium - Use NALFLEET 2000 or Cooltreat AL

>10% Aluminium - Use Cooltreat AL

Sampling and Testing
The WSS Motor Ship Test Kit (777066) provides the necessary equipment to carry out the control tests. Obtain a representative sample of the cooling water. Carry out the tests immediately after sampling (following the instructions given in the Test Kit) and log the results in Waterproof. The results should be sent to WSS as stated in the Waterproof instructions. It is important that testing is carried out at least once per week, to ensure levels of treatment are correct.

Dosing and Control
Engine cooling systems should be drained, flushed and if necessary, chemically cleaned, to remove old rust and scale deposits before treatment with NALFLEET™ 2000 can begin.

NALFLEET™ 2000 is easy to apply as received, and is fully compatible with water in ethylene glycol solutions. It contains an anti-scalant which helps to keep engine systems clean and free from corrosion and scale formation. NALFLEET™ 2000 maintains design heat transfer efficiencies and extends the life of the engine.

Cases of unusual coolant loss should be checked and remedial action taken. NALFLEET™ 2000 should be introduced during circulation of the cooling water. NALFLEET™ 2000 is best added by means of a feeder installed on a by-pass to the circulating system or in smaller systems, it can be added directly to the header tank. Initial treatment is at a rate of 32 liters of NALFLEET™ 2000 per 1m3 of coolant to give a control level of 700 to 1500ppm as nitrite (1000 to 2250ppm as sodium nitrite), pH 8.3 to 10.0. Overdosing with NALFLEET™ 2000 is not harmful to the system. Control by a simple test for nitrite and pH. Refer to table below for guide to dosing.

使用说明

NALFLEET™2000设计用于所有常见类型的发动机冷却水系统。Nalfleet 2000将保护黑色金属，铜和铜合金以及所有其他金属，包括铝组件
。NALFLEET™2000不会影响冷却系统内的橡胶垫圈或其他非金属部件
。

采样和测试

WSS Motor Ship Test Kit （777066）提供了执行控制测试所需的设备。获得冷却水的代表性样品。取样后立即进行测试（按照测试工具包中的说明）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。重要的是每周至少进行一次测试，以确保治疗水平正确。

剂量和控制

在使用NALFLEET™2000进行处理之前，应排空
，冲洗发动机冷却系统
，并在必要时进行化学清洁，以清除旧锈和水垢沉积物。可以开始。

NALFLEET™2000易于按原样使用，与乙二醇溶液中的水完全兼容
。它含有防垢剂，有助于保持发动机系统清洁，不受腐蚀和结垢形成。NALFLEET™2000可保持设计传热效率并延长发动机的使用寿命。应检查异常冷却剂损失的情况并采取补救措施。应在冷却水循环期间引入NALFLEET™2000
。

NALFLEET™2000最好通过安装在循环系统旁路上的进料器或较小的系统中添加
，可以直接添加到集水箱中
。初始处理的速度为32升NALFLEET™2000 / 1m3冷却剂
，控制水平为700至1500ppm
，亚硝酸盐（亚硝酸钠为1000至2250ppm）
，pH值为8.3至10.0
。使用NALFLEET™2000过量使用对系统无害。

通过简单的亚硝酸盐和pH测试来控制
