Ameripro Service Systems, Inc. Fuel Treatment Division is dedicated to clean fuel. Ameripro Service Systems is your UP TIME specialist. We will never “down” a generator to clean fuel. Our process leaves the power unit ready on standby during the entire time we are on site. Over time, fuel collects dirt, water, and depending on environmental factors, bacteria and algae. Our Fuel Treatment Division can return most fuels to a near new specification. While some fuel treatment companies clean fuel “till it looks” clean, Ameripro Service Systems, Inc. takes a scientific approach and cleans fuel to a level that meets or exceeds the ISO 4406 rating that has been established for fuel cleanliness by the International Organization for Standardization.
