Dirty air coolers
Fouled Air Cooled heat exchangers lead to the following main failures:
LOW heat transfer efficiency
LOW pressure drop
High cooled fluid outlet temperature
High energy consumption (Fan power)
Low cooled fluid throughput
Low efficiency
Damage fins (from high pressure)
The client have to consider the cleaning process when thousands of dollars are sent to the flare.

The Air Coolers-Solution On-line cleaning treatment is based on low-pressure spraying of Furnace Solutions Treatment Chemicals, directly onto the aluminium tubes bundles. This process is a unique combination of both Chemical and Mechanical cleaning.
Furnace Solutions Treatment Chemicals are granular solids, sprayed onto the bundles by compressed air through an air jet.
While spraying, the electrical motor should be turned off for a short period of time, approximately 20 minutes. Other motors can work.
This way of On-Line cleaning can be done without disturbing the production process.
While spraying, there is no need for extra scaffolding.
During the On-Line cleaning treatment, the following parameters can be monitored:
Inlet/outlet temperature of the cooled fluit (DeltaT)
Power of the fan
Airflow in the plenum

Tubes with reduced / no flow show as colder(darker) . Visually this can be seen as hogged (or distorted/ snaked) tubes. This effect is caused by the tubes that have flow in them being longer (thermal expansion) whilst the cold tubes are still locked into the header boxes that are free to move with the rest (majority) of the hotter tubes.
Our employees are very committed and have years of experience in On-Line Furnace cleaning.
We specialize in solving complicated problems, such as plugged convection, poor access to radiant or convection, poor efficiency of the Furnace, refractory or ceramic fiber which should not be damaged, etc...
We can respond very fast to your requests, to help you achieving more efficiency in less time.
We are very accurate with safety and therefore are able to show a record of no incident or accident since 2007.
This process is environmentally friendly. It does not create any waste, all chemicals are burned or disolved inside the furnace.
We are insuring that there is no smell or any disturbance for the neighbourhood. We managed in many countries to work accordingly to very strict authority regulations.
