DIESEL ENGINE WATER TREATMENT SUITABLE FOR ALUMINIUM, ALLOYS AND YELLOW METALS

RXSOL-40-4004 is an inhibitor concentrate/chemical which is added to the cooling water of internal combustion engines in cases in which the coolant does not need to be protected from freezing. It efforts excellent protection against cavitation and corrosion to all metals and alloys that are used in cooling systems.It is especially appropiate for the use in heavy-duty engines such as those used in trucks,  ships and lokomotives.

• High performance corrosion inhibitor
• Being a nitrite free product it is compatible also with zinc - coated piping
• Easy control test with refractometer.
