Gas Generator Sets

Combined heat and power (CHP)

Whether your operations require steam, hot water or even hot air, Caterpillar offers CHP modules that recover the heat from the engine jacket and aftercooler water circuits, and/or from the exhaust gas. Caterpillar offers a standard or customized CHP design to match customers’ needs with the cooling configuration, system pressures and temperatures associated with each Cat® gas engine.

Controls and switchgear

Whether operating on natural gas, biogas or manufactured gas, Caterpillar offers switchgear controls that match regional requirements. CAT paralleling, control and monitoring systems are offered to serve International Electrotechnical Commission (IEC) standards in India. All controls are microprocessor-based with redundant backup master controls via the individual generator control processors. Full monitoring and control are offered locally via a 5.7 to 17 inch (145 to 432 mm) color touch screen interface.

Fuel systems

Whether your natural gas project requires simple fuel pressure regulation and safety, or if your biogas generator set requires filtration of hydrogen sulfide and siloxane contaminants, a complete offering of fuel train equipment is available to meet the specific needs of your project. For low energy fuels, Gmmco will analyze your fuel sample to ensure compliance with CAT engine fuel requirements over time.

Exhaust aftertreatment

Caterpillar offers a suite of aftertreatment solutions to comply with any global regulation. Whether you’re applying a lean burn engine oxidation catalyst to simply lower CO emissions, or applying a urea-based SCR system to all but eliminate NOx for greenhouse fertilization, CAT Gas Solutions provides exhaust aftertreatment equipment tailored to your regional requirements.

Containers and enclosures

For both natural gas and low energy fuel applications, Caterpillar offers containerized power plants that include complete generator sets, paralleling controls, cooling system, oil system and ventilation for various ambient environments. Custom containers are offered for arctic grade -40°C (-40°F) and high ambient project locations up to 50°C (122°F).

Cat Financial is a full service finance company offering both loans and leases at competitive interest rates and flexible terms on equipment and projects powered by CAT engines. Construction and term project financing is available for up to 80 percent of the total project cost, including engineering, equipment, permitting and soft costs.

Trade

For more than 30 years, CAT World Trade has helped companies with an alternative means of purchasing Cat equipment through innovative commodity trade agreements. Cat World Trade can also help generate more revenue through the sale of carbon, renewable energy or emission reduction credits.

Gas rental power

Sometimes bridge electric power solutions are required to close the gap during major construction projects, utility power shortages or expansions of commercial or industrial operations. Cat Rental Power via the global network of Cat Rental Power Dealers and International Power Project Providers offer containerized, mobile generator sets that can operate on natural gas fuel, individually or paralleled together, on a monthly or annual contract basis.
