Benefits

Minimises sludge and scale deposits

Approved by major diesel engine manufacturers

Test Kit for Nitrite, Chloride and P Alkalinity.

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.

Sampling and Testing
The WSS Nitrite Test Kit (777067) 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 1000ppm nitrite (1000 to 1500ppm as sodium nitrite). 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.
