ECONOMIZER FT (Soot Remover Liquid, Veclean Econotreat, LT Soot Release)


*       Effective  above 200 °C

*       An easily dosed liquid

*       Complete coverage of entire exhaust gas unit

*       Greatly improved heat transfer

*       Neutralises sulphuric acid

*       Reduces corrosion and fire risk


Today’s main propulsion units have low exhaust gas outlet temperatures. This is due to increased engine and turbo blower efficiency. Lower gas temperatures are also the result of running at reduced power. The low temperature and reduced gas volume gives increased soot deposition and subsequent corrosion.

The increased deposition greatly reduces the thermal efficiency of the economizer. As "dew point" is often reached in the unit, causing the generation of sulphuric acid, the corrosion process is greatly accelerated.

Economizer FT is a specially developed liquid which is easily dosed into the system, using a special StarMarine injection unit. The special air assisted nozzles create a fine mist so that the liquid vaporizes on contact with the hot gas. The vapor mixes intimately with the exhaust gases and the active material is dispersed throughout the system in microscopic particles. These tiny particles have an extremely large "active surface area" and being light; remain in the gas fully dispersed. This ensures that all parts of the economizer are covered efficiently.

Economizer FT catalyzes the post combustion process, resulting in modified soot particles which are dry and non adherent. The resulting deposit is more friable and can be more easily removed by the action of the soot-blowers.

Directions for use

Economizer FT is designed to prevent major build ups of soot in service.

Dosage instruction

1-2 liters of Economizer FT is required for every 1000 m2 of heating surface area. This amount should be increased / decreased dependent on economizer design and fuel consumption.

Dosage period

Economizer FT should be injected daily or twice daily after soot-blowing.

Dosing equipment

The product must be dosed via the specially developed StarMarine injection unit which is made of materials suitable for prolonged contact with Economizer FT. for further information please refer to the StarMarine equipment information sheet.

Injection points

In most cases a single injector can be put into the exhaust systems immediately after the turbo charger gas outlet.
