Catalyst TechnologyStationary Engines

Established in 1999, currently we provide catalyst solutions to over 2,600 customers in the USA/Canada and abroad.

Primarily focused on developing catalyst technology for diesel, gas, LPG, Natural Gas engine applications ranging in size from 5 kW to 4000 kW.

Our products have been successfully installed in North America, Asia, Australia, Africa, China, Eastern Europe and South America.

Products typically installed on mining, construction, power generation, small engine, utility/service vehicles, material handling, marine and on-road trucks and buses.

Oxidation/Particulate Reaction

CO (carbon monoxide) Reduced by 95-99%

HC (hydrocarbons) reduced by 80-90%

PM (particulate) reduced by 70-91% NOx (Oxides of Nitrogen) reduced by

30-50% on average in an uncontrolled reaction.

Reduction Reaction (3-Way)

CO (carbon monoxide) reduced by 95-99% HC (hydrocarbons) reduced by 80-90% NOx (Oxides of Nitrogen) reduced by 99%

CRT CO (carbon monoxide) reduced by 95-99% HC (hydrocarbons) Reduced by 80-90% NOx (Oxides of Nitrogen) Reduced by 25-

50% PM (Particulate Matter) Reduced by 95-

Standby

Average of 100 hours/year (results in an approximate lifespan of 15 to 20 years)

Prime

Average 5,000 hours/year (results in an approximate lifespan of 3 to 5 years)

Critical Power Competition

Basic Oxidation Catalyst Performance

CO = 95-99%HC = 80-90%PM = 70-88%NOx = 20-30%

CO = 60-70%HC = 40-50%PM = 20-25%NOx = Unknown

Product Availability 2-3 Weeks 6-8 Weeks

Product Lifespan(Stationary Applications)

Standby – 15 years (500 hours annual)Prime – 5 years (1500 hours annually)

Standby – 5 years (500 hours annually)Prime – 2 years (1500 hours annually)

Maintenance

Virtually none, our catalysts and CRT filters are designed to regenerate automatically at appropriate exhaust temperatures

Units must be removed monthly and sent off-site for costly maintenance. Limit to how many cleaning cycles can be done.

Effects on Engine Backpressure and Fuel Economy

Our stainless steel honeycomb catalyst substrate is 97% open cell structure translates into < 2” H2O and virtually no loss in engine power or fuel economy

Catalyst medium is primarily composed of Ceramic based medium which is only 60% open resulting in very high backpressue > 15” H20 which causes premature engine parts wear and loss of fuel economy and low catalyst performance.
