Product information

This product supersedes product no: 777704

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.

使用說明

NALFLEET™2000設計用於所有常見類型的發動機冷卻水係統 。Nalfleet 2000將保護黑色金屬 ，銅和銅合金以及所有其他金屬 ，包括鋁組件 。NALFLEET™2000不會影響冷卻係統內的橡膠墊圈或其他非金屬部件 。

采樣和測試

WSS Motor Ship Test Kit （777066）提供了執行控製測試所需的設備 。獲得冷卻水的代表性樣品 。取樣後立即進行測試（按照測試工具包中的說明）並將結果記錄在防水中 。結果應按照防水說明中的說明發送至WSS 。重要的是每周至少進行一次測試 ，以確保治療水平正確 。

劑量和控製

在使用NALFLEET™2000進行處理之前 ，應排空 ，衝洗發動機冷卻係統 ，並在必要時進行化學清潔 ，以清除舊鏽和水垢沉積物 。可以開始 。

NALFLEET™2000易於按原樣使用 ，與乙二醇溶液中的水完全兼容 。它含有防垢劑 ，有助於保持發動機係統清潔 ，不受腐蝕和結垢形成 。NALFLEET™2000可保持設計傳熱效率並延長發動機的使用壽命 。應檢查異常冷卻劑損失的情況並采取補救措施 。應在冷卻水循環期間引入NALFLEET™2000 。

NALFLEET™2000最好通過安裝在循環係統旁路上的進料器或較小的係統中添加 ，可以直接添加到集水箱中 。初始處理的速度為32升NALFLEET™2000 / 1m3冷卻劑 ，控製水平為700至1500ppm ，亞硝酸鹽（亞硝酸鈉為1000至2250ppm） ，pH值為8.3至10.0。使用NALFLEET™2000過量使用對係統無害 。

通過簡單的亞硝酸鹽和pH測試來控製 。有關劑量的指導 ，請參閱下表 。
