Vänersborg, Sweden
The Challenge
During the heating season, each boiler required three manual cleanings, each resulting in a 2-day shutdown.
These interruptions affected operational efficiency and increased maintenance workload. Vattenfall aimed to eliminate these shutdowns to improve reliability and reduce operational disruptions.

These interruptions affected operational efficiency and increased maintenance workload. Vattenfall aimed to eliminate these shutdowns to improve reliability and reduce operational disruptions.
The Solution
Vattenfall installed the Aerovit Soot Blower system on one of the two boilers. After just one heating season, the performance exceeded expectations.
The system allowed continuous operation throughout the season without the need for manual cleaning.
Due to these successful results, Vattenfall decided to equip the second boiler with the Aerovit system for the next heating season.
This is the result from the first boiler:
- No manually cleanings during the heating season
- Increased efficiency of the boiler from 85% to 93%
- Earned savings on approx. 110.000€/year

How does Aerovit Soot Blower work?
The Aerovit Soot Blower system is designed to maintain high boiler performance by removing soo t and ash deposits.
Aerovit Soot Blower uses pure compressed air to deliver powerful shock waves to clean boilers. In jusr fractions of a second, 450 liters of high-compressed air is released through the Aerovit valve, effectively dislodging sediments and ensuring consistent cleanliness throughout the boiler system.
Unlike traditional cleaning methods, this system operates continuously during normal boiler operation, minimizing downtime and improving overall efficiency.
