Johnson Matthey has introduced a new range of three-way and two-way catalytic converters and converter-silencers, it has been confirmed.

The fourth-generation EcoNOx products are designed to reduce harmful exhaust emissions and noise from any stationary gas engine.

Retrofit applications in gas compression, power generation, irrigation, pumping, standby equipment and pump jacks are the intended targets of the latest developments.

The converters are capable of reducing up to 99 per cent of NOx, CO, HC, VOC and hazardous air pollutants emissions from natural gas, diesel, LPG, duo or biofuel engines.

"At the heart of the EcoNOx converter is a catalyst element that is manufactured using highly dispersed platinum group metals," noted a report by Diesel Progress Online.

"The metal monoliths that support the PGM are brazed, thin-walled stainless steel honeycomb supports, which are nearly impervious to damage from mechanical or thermal shock and metallurgic erosion."

Johnson Matthey has four EcoNOx converters at present, including one for 250 to 2,000hp internal combustion engines and a mini version for those with 50 to 500hp.

The other two products are the EcoNOx Q converter-silencer and the EcoNOx Mini Q converter-silencer.

A recent study by the Environmental Protection Agency revealed that Johnson Matthey's emission reduction devices can cut the amount of particulate matter released from exhausts by up to a third.
