After the insolvency of the German company FEG Heizflaechen-Reinigungsanlagen GmbH, Rosink took over the brand-name "FEG" and all remaining records in 2005. FEG used to manufacture shot cleaning systems for the cleaning of downstream heating surfaces.

Therefore Rosink cannot only design and realize new plants but also assure the supply of spare parts for existing FEG shot cleaning systems.

During shot cleaning, small mild steel balls are pneumatically transported into the upper boiler section. Via a special distribution system the balls fall through the heating surfaces by gravity. Through the falling energy of the balls the deposits are removed from the heating surfaces and extracted at the dust outlet.
