The first heating engineering castings made in 1890 in the cast iron foundry that was established in Bohumín in 1888 were radiator sections which until that time had been imported from the United States and in 1920 they were followed by cast iron boiler sections for manufacturing of hot water boilers for central heating. Cast iron has a tradition of high efficiency, reliability, and long service life of boilers and radiators made by VIADRUS.

The current production range that contains OEM cast iron boiler sections, boiler drums and exchangers includes also other medium and large series commercial castings according to the customer’s documentation made of cast iron grade EN-GJL-150 a EN-GJL-200.
