Online (in-process) dry chemical cleaning of fin fan air cooler finned tubes  (external air-side of the tube), through pneumatic spraying of non-hazmat SENTROFINTM dry chemicals, applicable for both induced and forced draft finned tube bundles, in a horizontal or vertical configuration.    

• Conducted “on-the-run” during normal operating conditions with no loss of production
• Flexible scheduling for the cleaning – limited equipment access required
• Immediate measurable results and benefits – visible operational improvements while undergoing the cleaning process:

✔ Process outlet temperature reduced

✔  Production rate increased

✔  Fan speed (in variable speed motors) reduced

• No damage to tubes, fins, motors, belts, bearings, or instrumentation as compared to dry ice blasting or to fin-foam-and-water cleaning or other cleaning methods, as the cleaning method is non-aggressive and does not use high-pH or caustic materials;
• Little or no scaffolding is required – typical access from existing platforms
• No cleanup required – non-hazmat SENTROFIN^TM chemical appears like steam, does not settle, and disperses away
• Green Solution – No negative environmental impact
• No confined space entry

All of SENTRO’s cleaning and inspection systems are the result of practical applications combined with continuous research and development.
