Putting a Lid on Catalyst Issues
While it is a given that emissions control technology
must first and foremost remove harmful constituents from the engine exhaust gas stream, it is equally true that they must also be able to operate in the real world, where durability, reliability and serviceability are critical. It was with those facts in mind that DCL International
Inc., the Concord, Ontario, Canada, supplier of advanced emission control systems for stationary and mobile engines, developed the next generation
of its QUICK-LID catalytic converter system. The QUICK-LID catalyst systems, first developed in the
mid-1990s, are targeted toward diesel
and natural gas engines used in power generation, gas compression and other industrial drive applications.
The new QUICK-LID systems incorporate
a range of new features, most
of which are intended to improve serviceability
and access. “The main
objectives were to improve the reliability
of the system,” said John Muter,
technical manager at DCL. “Because
the whole purpose of the QUICK-LID
is to be a housing our customers interact
with, the main way to do that was
by making the maintenance easier.
“If it’s easier for them to maintain,
they’ll do a better job and the system
will be more reliable. They are
designed to serve for 10 years or
more and they’ll need to be maintained
many times during that life.”
Perhaps the most significant
enhancement of the new generation
QUICK-LID units is the elimination of
the gasket around the catalyst element.
The only remaining gasket in
the unit is located around the lid portion
of the catalyst housing to prevent
leaking. The elimination of the gasket
offers significant savings to the customer,
the company said, and also
allows for easy replacement and
cleaning of the catalyst element.
“You will never have to purchase
another gasket for your catalytic converter,”
noted Paul Cook, manager,
North American Sales-Industrial
Catalyst Division. “The gasket located
on the lid is made of durable material
that rarely needs replacing.”
