Thermal imaging of enameling furnaces

The performance of industrial enameling furnaces may gradually decline over time.

This may result in higher energy consumption (read increased enameling cost) and reduced quality of the coated surface.

In extreme cases the enameling furnace may even unexpectedly break down, because insulation has been damaged and/or worn out.

Therefore we suggest regular inspections & thermal imaging to identify major heat bridges and other spots with possible insulation issues.

Enamel frit formulation

As reported during the 24th International Enamellers congress in Chicago last May, vitreous enamel frit manufacturers, particularly in Europe, are working to reduce or eliminate the use of metals like cobalt and nickel as well as the use of boron compounds.

This effort is being driven by proposed EU standards for these metals in drinking water and food contact.

Glass-fused-to-steel tanks & silo’s

GFS (Glass-Fused-to-Steel) is a frequently used alternative name for vitreous enamel to describe the most durable coating for a storage tank or silo.

Depending upon the required functional coating characteristics, the applied enamel film may consist of 1, 2 or sometimes even 3 consecutive layers.

These tanks & silo’s are typically designed and manufactured according to AWWA D103-09 and/or ISO 28765.
