When changing to RHOBA SUPRA C302 in systems that were previously operated with other products, we recommend rinsing sufficiently with water and decalcifying/cleaning the system beforehand. This must not be mixed with other products. The chloride concentration in the water must not exceed 50 mg/L and the water hardness 25 °dH. If one of these values is higher than described, deionised water (fully demineralised water) should be used for dilution.
Determining the concentration
The following table can be used to determine the current concentration via the density. In addition, the cooling temperature and the refractive index can be read off.
