ON-LINE Dry Chemical Cleaning of Furnaces, Heaters, Boilers
“On-The-Run” Dry Chemical Cleaning
SENTRO TECHNOLOGIES USA, LLC specializes in furnaces, heaters and boilers chemical cleaning during normal operating conditions.
There is no need to shut down the equipment, production continues normally.
Cleaning process applied on external tube surface of both radiant and convection tubes (fire side).
We also dry-clean air pre-heating system, economizer, and other types of process equipment.
A Process of Chemistry & Physics
Cleaning is done by combination of mechanical effect and chemical effect – simultaneously.
The mechanical effect is non-aggressive abrasion over the tube surface, without damaging the surface, fins, or refractory.
The chemical effect is a neutralization reaction between alkaline SENTROMAX chemicals and the acidic scale, hot spots (usually sulfuric) and fouling deposits.
This innovative dry cleaning process is safe, environmental-friendly and cost effective.
We anticipate that the SENTROMAX On-Line Dry Chemical Cleaning of process furnaces, heaters, and boilers will deliver the following benefits and results:

We anticipate that the SENTROMAX On-Line Dry Chemical Cleaning of process furnaces, heaters, and boilers will deliver the following benefits and results:
- Cleaning is performed On-Line during normal operating conditions of the unit, there is no need to shut it down.
- Removal of scale and fouling from external tube surface, Radiant and Convection tubes, thereby increasing thermal efficiency (heat transfer). As a result, reducing operating energy consumption and increasing production rate.
- No Scaffolding required.
- No water, no water-treatment.
- No dry-Ice (no thermal shock to tubes, especially to cast iron tube-supports)
- No foam or soap (no caustic stress corrosion cracking)
- No clean-up or disposal requirements
- No harmful chemicals (no negative environmental impact)
- No damage to tubes, fins, refractory, instrumentation.
- No confined space entry
Major Benefits
- Immediate increase of furnace or boiler thermal efficiency
- Immediate increase of throughput / production
- Energy saving by reduced fuel consumption
- Reduced emission / pollution
- Reduce temperature profile of the furnace or boiler (cell, bridge wall, stack)
- Pre-shut down activity – saves time and costs
- Saves maintenance activities (such as: scaffolding, sand blasting, water blasting etc..)
Our On-Line Cleaning Process is SAFE and Environmental Friendly:
- Developed over years of R&D and field experience
- Chemicals are Non-toxic, Non-hazardous, Non-corrosive, Non-poisonous, Non-flammable, Non-explosive, Non-transport regulated
- No damage to metallurgy, refractory, and instrumentation
- Chemicals completely decompound in high temperature
- Chemicals are compatible with all types of furnace or boiler metallurgy

Furnace On-Line Dry Chemical Cleaning (night shift):
note the light plume of white smoke, that appears like steam
SENTROMAX dry chemicals are non-hazmat, non-toxic, not regulated for transport
SENTRO setup near the furnace: Equipment, Chemicals, Air Compressor and Hoses – our footprint is small.
