RLF operates its AdBlue manufacture and distributor under the retail brand INERXA.

INERXA AdBlue® is a reduction agent for oxides of nitrogen (NOx), required by Selective Catalytic Reduction (SCR) technology in diesel vehicles. SCR systems need the continuous provision of a solution of urea at 32.5% in order to operate correctly and efficiently. SCR technology has been developed to fulfil the requirements of regulated emission standards.

In recent years environmental concerns have led to the introduction of SCR systems to assist with the lowering of emissions and greenhouse gases.

INERXA AdBlue® works in the following way :

Vehicles that use SCR are fitted with a diesel exhaust catalyst or a diesel particulate filter (DPF). In the SCR system, an aqueous urea solution is injected into the hot exhaust gas prior to the gas reaching the exhaust catalyst or DPF. When this solution makes contact with the hot exhaust gasses, it releases ammonia. When this reaches the catalyst (DPF), it then causes a reaction where the noxious gases are broken down into nitrogen, oxygen and water.


INERXA AdBlue® is added to a specially designed separate storage tank on SCR-equipped vehicles. It is dosed into the system at a rate equivalent to 3-5% of diesel consumption.

SCR systems are sensitive to chemical impurities in the urea solution, therefore it is essential that high quality control is maintained and important that INERXA AdBlue® is kept in accordance with the quality standards expressed in ISO22241.
