ELBLAST™

The ELBLAST™ process is a non-destructive method for dry on-line cleaning specially adapted for induced draft air cooled heat exchangers. We propel Sodium Bicarbonate (Baking Soda) with compressed air through a blasting unit and out of a special blast nozzle.

What blasting material is used?

The ELBLAST™ material consists of formulated sodium bicarbonate (also known as baking soda) having a crystalline structure that has a naked eye appearance of course granular sugar as opposed to the conventional powdery baking soda. The ELBLAST™ process of cleaning is an extremely friable material that has micro fragmentation on impact, literally exploding away surface materials without damage to the substrate. The unique properties of sodium bicarbonate allow it to remove dust, grease, oil, soot, pollen and other contaminants without damaging the thin metal sheet of the fins of the air cooled heat exchangers tube. There are no other blast media that have the same characteristics.

Our product used is non-abrasive, dissolves in water, and is formulated to be pure and free flowing.

The ELBLAST™ is sprayed using compressed air directly onto the fins. It quickly cleans the metallic surfaces with no abrasive effect thanks to the use of low pressure compressed air. The cleaning operation is followed by a light rinse in order to eliminate the ELBLAST™ residues on the fins.

The ELBLAST™ process is mainly used to clean “critical” air cooled heat exchangers and allows these facilities to recover close to design values running characteristics.

The ELBLAST™ method is a self-contained system that includes a blast generator, high pressure compressed air, moisture decontamination system, blast hose with remote controls, and a blast nozzle that is capable of handling our special blasting material

Benefits of ELBLAST™

1 SAFETY:

  • No entry inside plenum chamber anymore, thus
  • No risk of accidents due to  heat stress
  • Risk of accidents with running fans
  • No high pressure  application anymore
  • Nontoxic and biodegradable formulation : no treatment of the liquid waste is required

2 COST IMPROVEMENTS FOR THE FUTURE

  • No production losses as on line cleaning (while fans are running)
  • No more lengthy motor isolation procedures as cleaning can be carried out while fans are in operation (on line cleaning)
  • No scaffolding  or wooden boards required
  • No damage on fins  due to spray jetting as the work pressure is low (8-10 Bar)
  • No risk of  damage of fins as no walking on fins at all anymore as we stay under the finned tube bundle
  • No lengthy  issuing of entry permits anymore
  • No damage on pumps, motor, bearings due to water
  • no EEC classification for transportation or storage
