SILEX INNOVATIONS INC. New from Silex is the MAXIMSilex line of compact combination diesel emissions exhaust particulate filters for power generation applications. Known as the DEmEx, these fully insulated units are compact with sliding service access panels located on the side rather than the top — making them suit- ed for gen-set enclosure installation and applications where space and service options are limited. The side openings have side hatch covers that slide away rather than needing cranes or multiple personnel for access to the DPF retain- ing system for service or inspection. The CARB Verified Level 3 Plus cat- alyzed DPF elements are designed to remove more than 95% of PM, CO and THC emissions and are available in critical, super-critical and hospital- grade acoustic performance levels. Each DEmEx ships with the MAXIM- Silex differential pressure and tempera- ture monitor with programmable set- points that allow the end user to tailor the service interval to suit the operating conditions encountered. Silex has also introduced MAXIM Silencers, a range of combination cat- alytic exhaust silencers known as the quick access cover (QAC). The QAC is a patent-pending design that was engi- neered to be easier to install and more simple to maintain and operate. A flexi- ble hinge is used to apply the right amount of pressure while in use, while allowing the catalyst access cover to swing open without the need to carry or lift the access cover during service. The gasket-free seal between the catalytic core and housing allows the MAXIM QAC to comply with more stringent emissions reduction stan- dards. Each QAC is capable of hous- ing two catalytic cores, allowing for future upgrades with minimal service interruption. The QAC is also avail- able in a full range of acoustical per- formance grades.

SONCEBOZ The Sonceboz torque motor is a ro-
tary brushless actuator designed for en- gine control applications including flap and poppet valves for air intake and ex- haust gas recirculation (EGR) systems and variable turbine geometry (VTG). With peak torque up to 0.337 lb.ft. and fast positioning times below 100 ms, it operates as a direct drive with no gears. Depending on customer specifi- cations, additional functions can be integrated in a compact packaging — magnetic position sensor, return-to-zero spring or drive electronics. The device can operate as an on/off actuator with minimum energy consum- ption, and the integration of a magnetic position sensor yields an entirely brush- less servomotor, said Sonceboz. With integrated drive electronics, it operates as a stand-alone system compatible with bus communication standards.

UNIVERSAL EMISSION TECHNOLOGIES Universal Silencer has changed its name to Universal. The new name is in- tended to reflect the company’s devel- opments of core technologies within en- gine, blower, fan, compressor and vent acoustics and emissions applications. The name change is also in line with a series of strategic changes that have taken place over the past several years. The Universal name communicates a growing global presence, which is evi- dent by commercial and manufacturing locations throughout North America, Europe and Asia. Universal also has a division, Universal Emission Tech- nologies, led by Brian Kahl, vice presi- dent of Emission Technologies.

The InfraSpec VFA-IR Spectrometer
42 DIESEL PROGRESS NORTH AMERICAN EDI TION February 2010
TECHNOLOGY OF CLEAN AIR
from Wilks is engineered with a new flow-through sample system capable of accurately measuring biodiesel in diesel fuel down to 0.05% in less than one minute. This is particularly important for nuclear power plants and pipeline oper- ators as they need to ensure that little or no biodiesel is in their system. The analysis capability of the InfraSpec VFA-IR Spectrometer is suitable for on- site biodiesel measurements by non- technically trained personnel, Wilks said. It eliminates the need to wait for measurement results from an off-site laboratory. This spectral range analyzer contains a linear variable filter with a 128 pixel detector array covering a wavelength range of 5. 4 to 10. 8 µm and an integrated flow-through sample cell. The InfraSpec Spectrometer is com- pact, portable and has a simplified PC interface that gives the user the capabil- ity to measure on-site at a nuclear power plant or at a manufacturing facil- ity as well as in the laboratory or any- where measurements are required.
