Total combats SCR crystals with Clearnox
Total UK has launched its Clearnox AdBlue product, which prevents crystallisation in the selective catalytic reduction (SCR) system in on-road and off-road vehicles including HGVs, buses and coaches, as well as construction and agricultural equipment.
Clearnox can save fleets significant sums of money while minimising unplanned vehicle and equipment downtime, says Total.
Like regular AdBlue, Clearnox treats nitrogen oxide (NOx), but also helps avoid downtime by preventing crystallisation in the SCR system to help ensure it works efficiently and does not need to be replaced, thereby representing a potential saving of up to £3,000, the company says.
“Crystallisation is a problem that can arise when the exhaust gases are not hot enough to react properly with AdBlue so that it does not completely turn into ammonia,” said Total.
“When this happens, cyanuric crystals can form which can contaminate the system and bring the vehicle to a standstill.
“Clearnox is a ready-to-use urea solution suitable for all on-road and off-road vehicles and equipment fitted with SCR technology. It guarantees an optimal spray that ensures a complete reaction, even at low temperatures, to prevent crystallisation in the SCR system.
“Patented by Total and developed by its researchers in partnership with engine and vehicle manufacturers, Clearnox complies with the physical and chemical specifications in the ISO 22241 standard and ensures compliance with emissions levels in pollution and control standards.”
For optimal operation, Clearnox should always be used and the vehicle’s SCR system should be cleaned at a certified auto repair centre prior to the solution being introduced, Total advises.
Kevin Yeadon, Total UK heavy duty diesel oil/off-road channel manager, said: “Clearnox is beneficial for all on-road and off-road vehicles equipped with SCR technology including heavy goods vehicles, van fleets, buses, and construction and agricultural equipment.
“The biggest concern for fleet and equipment operators is with low temperature operation, where the AdBlue is not completely turned into ammonia, leading to crystallisation and costly repairs and unplanned downtime.
“The key question operators should consider is whether they are experiencing issues with crystallisation in their SCR systems. If they are, then Clearnox is the solution they need.”
