BLAST · DRY ONLINE CLEANING
BlueBLAST fin-fan cleaning.
A non-toxic, biodegradable dry cleaning method for air cooled heat exchangers, applied online with fans running or offline during outages.
The process
Clean fins, without water or downtime.
BlueBLAST propels a formulated sodium bicarbonate media with low-pressure compressed air through a blasting unit and a special nozzle. The media has a crystalline structure that looks like coarse granular sugar rather than powdery baking soda.
The material is extremely friable and micro-fragments on impact, removing dust, grease, oil, soot, pollen and other contaminants without damaging the thin metal fins. No other blast media on the market has the same characteristics.

How we clean
A self-contained system, applied online.
The media is non-abrasive, dissolves in water and is formulated to be pure and free-flowing. It is sprayed with low-pressure compressed air directly onto the fins and cleans metal surfaces quickly with no abrasive impact.
BlueBLAST is mainly used on critical air cooled heat exchangers, helping facilities recover close to design values and operating characteristics.

BlueBLAST capabilities
Online and offline cleaning, start to finish.
Every BlueBLAST job includes performance evaluation before and after cleaning, so you can see the airflow and heat-transfer recovery.
- Non-toxic, biodegradable formulation
- Online and offline cleaning
- Deep fin-pack cleaning
- Fouling and debris removal
- Fin straightening and inspection
- Airflow and heat-transfer restoration
- Pre- and post-cleaning performance evaluation
Benefits
Safer for crews. Better for production.
Cleaning online removes many of the costs and hazards of conventional water washing.
Cost improvements
COST- No production losses, since cleaning happens while fans run
- No lengthy motor isolation or entry permit procedures
- No scaffolding or boards required
- No fin damage from jetting: work pressure is low (8–10 bar), and crews never walk on fins
- No damage to pumps, motors or bearings from water
- No water waste management and no hazardous classification for transport or storage
- Full capacity year-round when combined with CLEANFIN™ filters
