Its CVRAS approval means that the SCRT system can be used to upgrade vehicles for the London Ultra-Low Emission Zone (ULEZ), Clean Air Zones (CAZ) and Scottish Low Emission Zones.
The system reduces NOx and NO2 by up to 99%, and particulate matter by up to 95%, – results that have been proven in real-world urban operation.
It has already been used to upgrade thousands of heavy-duty vehicles worldwide
, including hybrid vehicles.
SCRT technology, combines the Continuously Regenerating Trap (CRT) and Selective Catalytic Reduction (SCR) to produce a system which reduces Particulate Matter (PM) by both mass and number.
It is a cost-effective way of upgrading vehicles to the latest emissions standards as around 15 vehicles can be retrofitted for the cost of one new bus.
The system is available with either the standard AdBlue dosing system or the Ammonia Storage Delivery System (ASDS) from Amminex
for 99% NOx reduction, even at low operating temperatures without urea deposit build up.
SCRT technology has been used extensively to reduce city bus emissions, and can also be applied to hybrid vehicles. We have more systems in operation across Europe than any other system of its type.
