ContiTech offers second-generation selective catalytic reduction (SCR) and charge-air lines that conform to Euro 6 and EPA 10 standards and feature plug-on-sleeve heated quick connectors with optimized contacting performance. Diesel engines use SCR technology to transform NOx into steam and nitrogen with a urea solution; heating the SCR lines prevents the urea solution from freezing in low temperatures. The line's spiraled heating conductor and bare crimped areas are protected against external influences including salt water and other media. Two-part injection-molded plug connections enable the creation of several variants, while the hoses' durable EPDM cover, combined with a butyl inner lining, improve impermeability. A plastic version for SCR systems with retractive suction is also available.
