The problem

The glass cooling fans on the furnace on site in Bulgaria could not meet the pressure requirements that were needed at the present time. We attended site, measured the airflow and pressure of the existing units that were running at 3000rpm.

Our solution

We supplied 4 new 500kW fans to produce 20% at its peak point of pressure if required for future processes. When running at normal operating pressure, considerable power will be saved.

The result

The company was able to:

  • Expand the range of glass produced with the additional pressure provided
  • Save circa 40% in electricity cost per annum due to the efficiency gain for normal processes
  • Fans were amortized within 12-18 months
