PROTECTOGEN C AQUA

CORROSION INHIBITOR

Protectogen® C aqua is a yellowish, water-soluble, glycol-free liquid which contains a highly efficient combination of corrosion inhibitors. The product is inhibited without the use of nitrite, amine, borate, phosphate, and silicate. The optimization of the corrosion inhibition system was performed without the use of CMR-substances ( C ancerogenic M utagenic R eprotoxic). According to the formulation, Protectogen® C aqua does not contain any restricted substances as described in the EG-guideline 2011/65/EG (RoHS = Restriction of Hazardous Substances), article 4 §1 like lead, mercury, cadmium, chromate VI, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE).

Protectogen® C aqua is delivered undiluted and should always be diluted with water. 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 also be added in closed heating systems if the possibility of oxygen access through seals or plastic elements can not be avoided.
