LISOL CryoGuard Blue – Additivated Urea Solution for Stable SCR Operation
LISOL CryoGuard Blue is a high-purity 32.5 % urea solution enhanced with specialized additives to improve the stability and cleanliness of SCR emission control systems.
The formulation meets ISO 22241 requirements and is fully compatible with conventional AdBlue® applications.
In situations where standard urea solutions may form solid residues or crystals, especially during low exhaust temperatures, LISOL CryoGuard Blue promotes more uniform decomposition and helps maintain the injector and SCR catalyst free of deposits.
Product Advantages
• Significantly reduces crystal formation and deposits in the dosing system
• Improves urea conversion efficiency under low-temperature operation
• Helps preserve injector precision and catalyst performance
• Supports longer maintenance intervals and reduces unplanned downtime
• Completely interchangeable with AdBlue® in all SCR vehicles
Typical Applications
• Trucks, buses, vans and construction machinery (Euro V / Euro VI)
• Vehicles operating in urban, cold or stop-and-go conditions
• Passenger cars and fleet-operated diesel vehicles with SCR systems
• Applications with consistently low exhaust temperatures
Complies with ISO 22241-1 / -2 / -3
Suitable for all SCR exhaust aftertreatment systems
