COOL TREAT NCLT is specialized Cooling Water treatment chemicals for a closed re-circulating water system. Suitable for all types of engines where water circulation permitted. Major engine manufacturers such as MAN Diesel and Wartsila have a suggestion to use proper balance dose of nitrite, borate and organics based corrosion inhibitor in water circular line.
Packing, Type 25 Ltrs
RXSOL Cooltreat is an organic liquid corrosion inhibitor with low-toxic property provides long-life corrosion protection for closed cooling water systems Rxsol Cooltreat will protect all commonly used materials in engine cooling water systems, including aluminium. Cool treat does not contain components subject to rapid depletion. Cooltreat is stable and biodegradable
Liquid product, easy to use. Environmentally friendly, fully organic product, low toxicity. Effective against cavitation and erosion. Superior heat transfer properties. Compatible with hoses, gaskets and seals. Compatible with glycols for frost protection. Stable product – non-depleting. The product can be used for corrosion inhibition in many types of closed re-circulation system such as: – Diesel engine cooling water systems – Compressor cooling water systems – Centralised cooling systems – Hot water heating systems – Auxiliary machinery cooling systems.
Using Method : –
RXSOL Cooltreat is a highly effective corrosion inhibitor for all common metals in cooling water systems.Where most traditional inhibitors react with the metal surface and form oxides that prevent further corrosion, Cooltreat applies a thin and durable layer of protective molecules to the metal surfaces. This technology prevents the continuous build-up of insulating layers on heat transfer surfaces.
For new builds, Rxsol recommends cleaning of the water system before commercing service. The system will always contain small amounts of oil and iron oxides, and this can be easly removed in 1 time with Rxsol Commissioning Cleaner. If the system is corroded or is more heavily contaminated use Rxsol Degreaser HD. Rxsol Safe Acid for removal of metal oxides or scale is recommended.
For systems previously treated with other products, Wilhelmsen Ships Service recommend to drain and flush the system before refilling with distilled water and Cooltreat . The system should be clean and free from scale and corrosion products when starting the treatment.
The use of antifreeze is sometimes required if the vessel is to be laid up in cold areas, Cooltreat can be used in conjunction with glycols for frost protection. If used in conjunction with glycols, It is recommended to increase the product concentration to 8%.
Cooltreat should be dosed to a suitable point in the system. If the expansion tank is used, adequate circulation must be assured.
Dosage and control
Cooltreat should always be present in a concentration of 5% or higher in the system. It is good practice to start with initial dose for an untreated system of 60 litres of Cooltreat /ton. 5% will provide sufficient protection of the system for a period of two to five years under normal conditions provided. To prevent residual falling below minimum level due to loss of cooling water, Wilhelmsen Ships Service recommend to maintain a level of 6% Cooltreat in the cooling system.
The engine manufacturer's recommendations for water quality should always be complied with. Cooltreat provides good protection even with contamination of the system by i.e. inorganc salts.Maintain Chloride levels and other contaminants at a minimum level. Most engine manufacturers recommend a maximum of 50 ppm Chlorides.
