Industrially significant results
98%+ NOx reduction achieved
Exceptional performance by ACCT-equipped passenger vehicle during high-load, lower ambient temperature driving (Majola Pass – Swiss Alps, April 2019)
The ACCT technology offers significant advantages over existing ammonia delivery systems for SCR which are unable to function effectively at low exhaust temperatures and can generate harmful deposits within a vehicle’s exhaust.

ACCT has excellent ammonia response times and availability as low as 50°C with full decomposition from 100°C:
- generates ammonia at almost all exhaust temperatures
- faster response for highly controllable ammonia delivery
- no deposit build-up, preventing any damage to the engine or after-treatment.
It is common, in existing systems, for the decomposition of AdBlue™ to be only partially complete before its arrival at the SCR catalyst. This can lead to deposit creation and requires either the SCR catalyst or an additional hydrolysis catalyst to complete decomposition.
With ACCT, decomposition is complete before the catalyst. So, there is no potential for the build-up of residue – allowing the control system to react more quickly.
