Advanced Power Systems International, Inc. (APSI) is a 30 year old company which was formed to develop, manufacture and market the Fitch® Fuel Catalyst technology. The Fitch Fuel Catalyst is a true catalyst which reformulates gasoline, diesel, fuel oil and propane allowing the user to extract more energy from these fuels. By doing so the user can either increase performance, in terms of horsepower and torque, or increase fuel efficiency by using less fuel to do the same amount of work. It can also produce a combination of both depending on the application.

Because the Fitch Fuel Catalyst causes more complete and efficient combustion there is less residue left after combustion something which you know of as “emissions”.  Thus Green House gases and pollution are reduced significantly. 

APSI markets its products to a whole host of users ranging from power sports enthusiasts (motorcycles, ATVs and snowmobiles) to the commercial and residential heating markets (furnaces and boilers), from the automotive market to the commercial and recreational marine markets.

APSI’s products are marketed by third party distributors and dealers, as well as directly, to these various markets. To date APSI's products are used on hundreds of thousands of applications. Customers include many Fortune 500 companies, the US Navy and Air Force National Guard, and many municipal and state agencies. In the New York City heating market alone APSI's technology is installed on over 1,000 schools and large commercial and residential buildings. 15,000 Fitch Fuel Catalysts are being used by customers in commercial and recreational marine markets. Well over 100,000 customers have purchased the Fitch Fuel Catalysts for their ATVs, snowmobiles, motorcycles, cars and trucks.
