arbcombo -- New Verification Executive Order—Rubber Tired Gantry Cranes

Posted: 25 May 2011 09:00:20
The Air Resources Board (ARB) has verified RYPOS, Inc. active
diesel particulate filter ActiveDPF/CTM for certified Tier 3 or
older diesel engines used in rubber tired gantry (RTG) crane
applications operating on CARB Diesel fuel.  The RYPOS
ActiveDPF/CTM active diesel particulate filter uses an active
flow through filter followed by a diesel oxidation catalyst (DOC)
to achieve an 50 percent reduction in particulate matter
emissions qualifying it for a Level 2 Plus verification.  Level 2
Plus verification means that the system will reduce diesel
particulate matter (PM) emissions by 50 percent or more and meets
the January 2009 NO2 limit.  Specific engine conditions for which
the RYPOS ActiveDPF/CTM has been approved may be found in the
Executive Order.   

This RTG verification Executive Order is available on our website


The Regulation for the Verification Procedure for In-Use
Strategies to Control Emissions from Diesel Engines was created
and adopted by our Board on May 16, 2002. The goal of the
Verification Procedure is to ensure that verified systems produce
emissions reductions consistent with the verification level and
that they are durable and compatible with various engines and
applications.  Additional information on the regulation is
available at the following link:
