Surface protection and heat retention through reflection.
How can you increase exhaust energy while reducing surface temperature at the same time? We believe there is only one plausible answer to this question: iTEX REF-ISO. This technology reduces NOX values and CO2 emissions by increasing the temperature more quickly in the exhaust aftertreatment process.
iTEX REF-ISO technology is based on the iTEX ST insulation shell with all its benefits. The special feature of iTEX REF-ISO is that color pigments can be mixed in to improve heat insulation and energy retention. Yellow pigments are used to reflect heat radiation. This enables the exhaust gas temperature and exhaust energy to be increased while at the same time reducing the surface temperature of the outer liner. The pigment powder has good UV and light impermeability and is chemically inert as well as being resistant to heat and ultraviolet radiation.
