Background

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 response

We supplied 4 new 500kW fans to produce 20% more pressure for the highest pressure requirement and at the normal operating pressure save them power.

The result

The company was able to produce thinner glass, expanding the range of glass produced, and due to the efficiency gain saved 40% in electricity cost per year.
