Ceramic rollers: Nova HF

Nova HF    

Very high firing temperatures, very good performances in the event of thermal shocks, very low porosity and permeability to vapours: all these characteristics enable the ceramic roller NOVA HF to have exceptional performances.

NOVA HF offers a solution to every problem with firing in roller kilns.

Typical Use:

At high temperatures under heavy loads (for example klinker, very thick porcelain tiles, tableware, and so on) 

In the event of a very high chemical aggression by alkaline vapours

Yellow-coloured ends marked with number identifying the ceramic roller type
