Ceramic rollers: Nova VHR

NOVA VHR

Newly-designed aluminous ceramic roller revealing an excellent mechanical strength to heavy load and high temperature even when there is a chemical aggression by the alkaline vapours released from the glazed or the body.

Although fired at high temperature, NOVA VHR also features an excellent resistance to thermal shock thus making this roller extremely versatile in its applications.

Typical Use:

-      glazed porcelain tiles

-      Single-firing kilns having a large useful width

Identification with Black-coloured ends and marking with the lot number and roller grade.
