Protectogen C Aqua Corrosion Inhibitor for Closed loop Cooling and Heating system without frost protection. Corrosion inhibitor concentrate for cold water systems with closed heating or cooling circuits without frost protection. Permanently protect the metals of the cooling- and heating systems even in combined systems permanently against corrosion. Provides long-lasting corrosion protection. Without the use of nitrite, amine, borate, phosphate, and silicate. Without the use of CMR-substances. The concentration of Protectogen® C aqua in water should be 1.5 % v/v. That means that 1.5 l Protectogen® C aqua will be added into 98.5 l water. The water used to dilute Protectogen® C aqua shall contain no more than 100 mg/kg (ppm) chloride. This should be borne in mind particularly if systems contain components made of aluminium or aluminium alloys. A wide range of water hardness is acceptable (between 0 and 20° GH). This means that in addition to fully deionized water ordinary tap water may be used. Protectogen® C aqua is especially suitable for the use in cold water sets which do not require frost protection, i.e. in a temperature range from approx. +5 to +95 °C.This mixture does not offer any frost resistance and it is therefore not suitable for outdoor applications in winter. For protection from frost please use our products Antifrogen® N, L, SOL HT or KF. By adding Protectogen® C aqua the specific heat transfer abilities of water will not be influenced significantly at all. Protectogen® C aqua can be added in closed heating systems if there is any possibility of oxygen access through seals or plastic elements which can no be avoided.
