PURItech ON-Road Systems
The Appropriate System for Any Task
Developed by PURItech our retrofit diesel particulate filter solutions are precisely tailored to the needs of Heavy Goods Vehicle users.
All our filters meet the regulatory requirements of the Low Emission Zone and are customised into specific product offerings suitable for different types of on road use.
Our recommended products for Heavy Goods Vehicles are the DPFN, DPFN+ and DPFN++ systems.
To view all the technical information relating to each system please visit our downloads section.
The DPFN system is a self-regenerating particulate
trap that nearly eliminates Diesel particles and simultaneously reduces
NOx emissions. The DPFN system is designed for vehicles which operate a
medium to high-power regime and is ideally suited to vehicles that
travel continuous long distances.
DPFN+ System is a self-regenerating particulate trap with catalytic
pre-filter. This design enable the system to regenerate the soot that
occurs with lower exhaust gas temperatures usually found in urban or
extra urban traffic conditions. This system is ideal for long to medium distance light load journeys.
This system is also suitable for regional distribution traffic, city
traffic with little or no stop start and engine idling and construction
traffic with high engine load and short engine idle times.
DPFN++ System is a self-regenerating particulate trap with HC-Dosing.
This system was designed for vehicles with very low exhaust gas
temperature profiles that operate in a continuous stop-start
environment. The active active regeneration employs a nozzle in front of
the pre-filter where Diesel fuel is injected. The fuel combusts over
the pre-filter increasing the exhaust temperature which allows the
accumulated particles to regenerate. DPFN++. This system is ideal for city and urban traffic with stop start
journeys and long engine idle times. It is also suitable for Council /
Municipal vehicles such as Bin Lorries and Road Sweepers. The DPFN++
system is also suitable for retail / delivery vehicles and food
