GE Power

With over 100 years of engine design, development and manufacturing experience, GE’s Waukesha gas engines are redefi ning oil fi eld power generation in drill rig applications with a non-road US EPA mobile certifi ed solution that provides diesel-like performance, fuel fl exibility to run on natural gas/fi eld gas and low emissions output for excellent engine performance.

Operation – runs and provides power like a diesel without the cost of diesel fuelFlexibility – reliable, proven fuel fl exibility across a wide BTU rangeEmissions – Capable of ultra-low emissions, below 185 mg/Nm3 NOx. Mobility – Simple to package with a pony skid or tailboard skid for plug and play operationPower – maintains consistent power output across changing fi eld conditions

Newly designed, cost eff ective and durable three-way catalytic (TWC) converters are an integral part of our system for US EPA Mobile Certifi cation, which eliminates the need for costly on site emissions testing.

Designed to reduce nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC’s) by >95% on engines fueled with fi eld gas, LNG, CNG and HD-5 propane. Count on our catalytic converters to deliver easy maintenance, and maximum performance. The TWC has been sized to work in conjunction with our air fuel ratio control to meet the most stringent emissions requirements cost eff ectively..

At the heart of the TWC converter is the catalyst element, which is manufactured using suffi cient amounts of durable and highly dispersed Platinum Group Metals (PGM). Our metal monoliths supporting the PGM, are brazed, thin-walled stainless steel honeycomb, which are nearly impervious to damage from mechanical or thermal shock and metallurgic erosion.

Meeting your emissions requirements for NOx, CO and hydrocarbon (HC) emissions from mobile and stationary SI (spark ignited) engines is made easier with these new TWC converters. The TWC converters are formulated to achieve high conversion of formaldehyde and CO as well as NOx. The unique

design and construction of our catalyst element also reduces backpressure: This means fuel savings and longer catalyst life.

The TWC converter is a dual element design for the VHP5904/L7104GSI-MOB engines. Its removable cover allows easy access for maintenance and catalyst element replacement.

As an option; Waukesha TWC converter-silencers are recommended for use where equipment must operate continuously in quiet locations— near hospitals, schools, stores, apartments, hotels and residential areas.
