Advanced Power Systems International, Inc. (APSI) is a 30-year-old company which was formed to develop, manufacture and market the Patented Fitch® Fuel Catalyst technology. The Fitch Fuel Catalyst is a true catalyst, not a consumable additive requiring replenishing with every tank of fuel. As diesel, fuel oil, propane, gasoline and natural gas is exposed to this proprietary metal alloy, the fuel’s molecular structure is modified at ambient temperature to enable more efficient energy release during combustion, allowing engines and equipment to extract more usable energy from the fuel while reducing emissions and operating costs. The catalyst stimulates oxygenation, coupling and olefin formation while simultaneously promoting aromatic ring decomposition which leads to more complete and efficient combustion of the fuel. This allows engines to use less fuel for the same work while reducing emissions, engine maintenance, and downtime, and improving overall performance.

Because the Fitch Fuel Catalyst promotes more complete and efficient combustion, there is less unburned residue remaining in the exhaust stream, commonly observed as emissions. As a result, greenhouse gas output and other pollutants are significantly reduced.

APSI serves a broad range of markets, from power sports enthusiasts (motorcycles, ATVs, and snowmobiles) to commercial and residential heating (furnaces and boilers), to mining and construction equipment, powerplants, as well as the automotive and the commercial and recreational marine sectors.

APSI’s products are sold both directly and through an established network of third‑party distributors and dealers to these segments. APSI’s technologies are installed on hundreds of thousands of applications worldwide, with customers including numerous Fortune 500 companies, the U.S. Navy, the Air Force National Guard, and a wide range of municipal and state agencies. In the New York City heating market alone, APSI’s solutions are installed on more than 1,000 schools and large commercial and residential buildings. More than 15,000 Fitch Fuel Catalysts are in service in commercial and recreational marine applications, and well over 250,000 customers use the Fitch Fuel Catalyst on their ATVs, snowmobiles, motorcycles, cars, and trucks.
