Metallic substrates will not crack or disintegrate even under harsh operating conditions and offer best thermal durability. The ceramic substrates are canned using the tourniquet technology, which produces the most rugged and durable catalytic converters. Easy Maintenance . The cell densities of the catalytic monoliths are carefully selected for each application. There is very little risk of clogging by diesel particulates.
Most applications are virtually maintenance-free.
Low Pressure Drop . Due to thin walls and large frontal area the catalyst substrates have low pressure drop and do not cause any fuel penalty. Technologies offers two designs of both the standard and D-Series catalytic purifiers, as shown in Figures 1 and 2. Welded design is more compact and recommended for space limited applications. Clamped design allows for easy removal of the centerbody for inspection and cleaning.
