Our Key Differentiators

Major Benefits

On-Line Dry Chemical Cleaning of Furnaces and Boilers: dry cleaning of the radiant section, convection section, economizer, super-heater, air pre-heater, and other parts of the furnace or boiler. Cleaning performed during normal operating conditions, with no need to shut down the equipment.


On-Line Dry Chemical Cleaning of Fin Fans Air Coolers: dry cleaning of all types of air coolers – “A” type, induced draft and forced draft. Cleaning performed On-Line during normal operating conditions. There is no need to shut down the equipment.

SENTROJET – Fuel Additives

Specifically designed for coal, diesel, or heavy-fuels operated steam boilers. Additives can be added pre-combustion or post-combustion, and immediately reduce slagging or fouling, reduce corrosion rate, and increase the thermal efficiency of the boiler – leading to immediate energy saving.

Acoustic Pulse Reflectometry (APR)

Ultra-fast, non-invasive sound-based ID inspection of heat exchanger tubes up to 4” size, to replace EddyCurrent.

SENTROKLIN – Vapor Phase Chemical Cleaning

Chemical cleaning for heavy oil units performed by injection of concentrated chemicals into low or medium-pressure steam. This is a very effective and cost-efficient cleaning process that can be applied to towers, vessels, tanks, pipes, heat exchangers, reactors, flare lines, draining systems, bottom or overhead systems, for example, Crude, Vacuum, Topping, FCC, Visbreaker, Coker, Platformer/Reformer, Hydrocracker/Hydro-treater, etc.

Acoustic Emission Testing

Inspection and testing performed On-Line during normal operating conditions of the equipment.
