Liquid Engine cooling water corrosion and scale inhibitor
Aquamarine Corrosion Controller is an easy to use liquid that inhibits electrolytic corrosion, cavitational corrosion and controls scale and sludge. It is also compatible with a wide range of hoses, gaskets and seals.
Aquamarine Corrosion Controller passivates metal surfaces and combines with sludges, scale and rust deposits to allow their gradual removal.
• Internal combustion engine and compressor cooling systems.
• Heat pump water systems.
• Recirculating cooling water systems.
• Hot water heating systems.
• Suitable for jacket water used in evaporator feed heaters.
• Chilled water systems.
• Hot chilled water systems.
• Ice melting water systems.
• Compatible with Ethylene Glycol used as antifreeze.
Aquamarine Corrosion Controller should be fed directly by the bypass pot feeder to the main circulating line or into the cooling water expansion tank.
(For systems using totally de-ionised water raise nitrite levels to 1700 p.p.m. as corrosion is more likely.)
Control is based on nitrite concentration and additions should be made after
representative sampling. Aquamarine test kit is available for accurate checking.
