was able to measure low exhaust backpressure with this filter compared to its
other systems.
Mobiclean R filter systems have been
tested under extreme conditions and have
proven to be maintenance free over the
lifespan of a vehicle, said Hug. The retrofit
kit is safe, easy and quick to install.
In addition to this new filter system, Hug
Filtersystems AG is also offering a broad
assortment of filters under the “Mobiclean
R” brand for all classes of diesel engines.
Hug Filtersystems is working closely
with partners and subsidiary companies
all over Europe and the United States.
The latest addition is the company Hug
Filtersystems Inc. in Austin, Texas, U.S.A.

Huss Group
The companies of the Huss Group
produce exhaust aftertreatment for
diesel engines, with focus on both first
installation and retrofit of off-road and
heavy-duty applications.
CleanDieselCeramics, a producer of
LPS-SiC ceramic for particulate traps, and
Metpela, a specialist in noise reduction and
metalworking, stand for the production
facilities of the Huss Group.
Retrofit solutions are represented by
Huss in Germany, Switzerland and North
America as individual entities. Authorized
partners are located internationally to
serve customers’ needs.
Huss produces aftertreatment systems for first installation and retrofit
of off-road equipment and heavy-duty vehicles.
In 2009, employees at Nuremberg,
Germany; and Palm Springs, California,
U.S.A., have moved to new premises,
with a doubling of space in Nuremberg
and a triplication in California.

Johnson Matthey Plc — Emission
Control Technologies (ECT)
Johnson Matthey’s Compact Soot
Filter (CSF) for light diesel engines has
been recognized in both the International Trade and Innovation categories of the Queen’s Awards for
Enterprise 2009. These awards are a
highly regarded corporate accolade for
U.K. businesses.
Johnson Matthey has expanded its
capabilities with the acquisition of the
assets of Applied Utility Systems Inc.
(AUS) from Catalytic Solutions Inc.
AUS specializes in SCR systems for
reducing NOx emissions from gas turbines, boilers and process heaters and
is a direct fit with Johnson Matthey’s
SEC emissions control business for
coal-fired power plants, process industries and internal combustion engines
for power generation, locomotive and
marine applications.
Johnson Matthey’s AdvCCRT (
Advanced CCRT) system, the second-generation benchmark CCRT filter
technology for 2. 5 g NOx EGR and non-EGR engines, has been verified by the
Environmental Protection Agency
(EPA) and California Air Resources
Board (CARB) for reducing PM by more
than 90%, while meeting stringent NO2
slip requirements.
The system uses three distinct catalyst formulas specifically engineered
for optimum performance. Upstream, a
Johnson Matthey oxidation catalyst
coated on a flow-through substrate
optimizes conditions for the second,
downstream catalytically coated wall-flow filter to burn off virtually all PM.
The third catalyst, an NO2
decomposition catalyst, then reduces NO2.

Liq Tech A/S
Liq Tech A/S has plans to introduce
two types of LiqTech kiln furniture:
Infiltrated SiC (SiSiC) for furnaces going
up to 1380°C in an oxidized atmosphere
and Recrystallized SiC (ReSiC) for
2000°C in an inert atmosphere.
Mann+Hummel’s latest development
in the field of DPFs is the SintROC filter, which reduces soot and NO2
emissions of diesel engines. The series was
developed for nonroad vehicles and
includes six sizes for engines in the
output range of 75 to 600 k W.
The SintROC filter from Mann+Hummel
is available in six sizes for engines
ranging from 75 to 600 k W.
The SintROC DPF combines the advantages of the existing Mann+Hummel
passive DOC systems and SMF-AR DPFs
into one product. As with a DOC system,
the SintROC regenerates continuously
without downtimes. However, it does not
require constant high exhaust gas temperatures, just a temperature above 380°C for
10% of the operating time, Mann+Hummel
said. This requirement is usually satisfied in
the engine output range for which SintROC
was designed.
That means that the SintROC, like
the SMF-AR, is a filter that offers a higher performance for applications with
intermittent exhaust gas temperatures.
These advantages are made possible because the filter element has a
higher ash-holding capacity and can
