The Company


Novaref is a division of VR Group founded in the middle of the eighties at Colognola ai Colli.
The company operates in two distinct markets: production of refractory rollers and special pieces for buildings.
The reference point for refactory rollers is that of the ceramic industry where they are used in the firing process of porcelain, both single fired and double fired.

The Ceramics division of VR Group has a subsidiary in Spain: Novaref Iberia.

Specialised rollers however are also destined for the building sector to be used in the production of facades for architectural constructions unique and innovative.
Thanks to our depth of experience in these two sectors, our group can say that we are world leaders in the design and production of ceramic rollers.
Our principal clients are: I.C.F. & Welko S.p.A., Cooperativa Ceramica D’Imola S.c. , Pamesa Ceramica, Sacmi Forni S.p.A., SITI-B&T Group S.p.A.

Branded Novaref products can resist thermal changes over long periods of time. Moreover, they can perform without reacting chemically to the other materials with which they are in contact. The rollers require special processing to maintain high quality standards and not break during the heavy stresses to which they are being subjected. VR Group products are used in many sectors due to their versatile technical specifications.

The development of ceramic is characterized by:

  • Increase of ceramic roller dimensions
  • Increase of the product weight due to oversized thickness
  • New laminated products
  • Higher firing temperatures, especially for porcelain tile.

The subsequent increase of thermomechanical stress has highlighted the need of ever increasing dimensions and higher ceramic roller grades.

Novaref  suggests the following ceramic rollers:
Nova FX  –  Nova HF-XP Extremely high temperature and/or heavy loading
Nova HF  –  Nova HF-CR  –  Nova VHR Firing zone for floor and wall tiles
Nova SIX  –  Nova 421 Preheating and/or colling zone for floor and wall tiles

For the rapid cooling zone are also available our grades: Nova SiCar – Nova ST

ZMS-MULLITE GRIT is a first quality refractory material, composed of mullite and corundum crystals.

It is produced by sintering a compound of alumina and clay in a shuttle kiln at around 1500° C.

It gives high resistance to thermal shock and chemical corrosion at elevated temperature, low-reversibility thermal expansion and excellent thermal stability.

ZMS-MULLITE GRIT is used in the refractory and iron/steel industries as well as in the ramming mixed and refractory mortars.

Chemical composition:
