diamorph hob certec offers a full range of ceramic rollers that are used by producers of ceramics as essential parts of kilns and by kiln manufacturers. We have developed special products that suit each type of kiln.

Standard rollers



The most economical roller designed to be used under standard working conditions in the preheating and cooling zone and, even for light wall tiles in the firing zone.



Superroll has a higher module of elasticity than Specialroll, and this is why it is possible to install it under higher loads. This ceramic roller constitutes an economical option in the hob certec portfolio, and it is to be used in firing zone with heavy wall and floor tiles.


Hyperroll - L

Economical version of Hyperroll-NG to be used in those cases when the thermal shock resistance is not the main priority, but it is still necessary to use a high specification technical ceramic roller.

It is a roller with a high module of elasticity which allows using it in the firing zone when the rollers work in clean conditions and under moderated chemical attack.

Technical rollers


Hyperroll - NG

This roller has been designed considering all the factors that influence the thermal shock resistance of a ceramic roller. These factors include the thermal expansion coefficient, thermal conductivity, modulus of elasticity, chemical contamination inside the kiln, porosity, roller size, and more.

It is the roller with the highest thermal shock resistance available in the market. The operating costs of running the kiln are reduced because, in many cases, rollers can be extracted from the firing zone even at maximum temperatures without any breakages. Additionally, the high modulus of elasticity helps maintain the quality of tiles in optimal condition.


Hyperroll - X

A technical roller specifically designed to withstand the highest loads in the firing zone, Hyperroll-X is the preferred choice for any area of the kiln where other materials fail to provide sufficient tile support due to the weight of the tiles or the dimensions of the rollers.

In recent years, as kiln sizes have increased, more and more kiln users are opting to install this state-of-the-art roller design in greater numbers.


Hyperroll - D

For optimal kiln operation and achieving the highest output of premium quality tiles, Hyperroll-D (Dense Nano) is the unrivaled ceramic roller available in the market. It possesses two key advantages: zero porosity and very high modulus of elasticity (MOE). These characteristics contribute to superior performance in tile transportation and final tile quality by minimizing roller bending.

The zero porosity of Hyperroll-D also provides exceptional resistance against chemical attacks.

Hyperroll-D delivers the best results when installed from the kiln entrance up to the first module, as this is where chemical and physical pollution are most prevalent. It is crucial to install these rollers at temperatures of 650 °C or below.


Hyperoll - IQ

Universal Intelligent solution for production of all kinds of quality tiles in terms of planarity, straight trajectory in the kiln, reduction of defects and deformations.

Hyperroll IQ offers a unique combination of benefits, including chemical resistance, thermal shock resistance and strength. As a result, Hyperroll IQ can be effectively utilized in every module of a roller kiln.

grafika Hyperroll XT

Hyperroll - XT

Hyperroll EXTREME is the most extreme roller in the world ,with MOE of 200 GPa.

This roller has been designed to withstand the most extreme loads 20-50 mm of tile thickness.

This unique roller enable to charge the maximum width of kilns channels with tiles in order to use their production capacity with maximum efficiency.

Thanks to its very low porosity the roller resists very well to aggressive chemical attack.

The best ceramic roller solution for the rapid cooling zone

The Superringroll greatly improves the quality of the tile production creating a more uniform cooling of the tiles in the rapid cooling zone. The design of the Superringroll is the best roller solution to avoid the deformationin this area by reducing the contact area between the roller and the tile.

The Superringroll reduces the internal thermal tension of the roller and tile allowing a more uniform heat distribution between the tile and roller due to an excellent flowing of the cold air.







Hyperroll – RCZ

A stiff roller with zero porosity and with higher thermal conductivity, intended to reduce the roller deformation in the rapid cooling zone

The rapid cooling zone has really specific characteristics which must be taken into account and analyzed in detail. In this area, tiles undergo a really fast and sensitive process which can ruin their final quality. The upper side of the roller is in contact with the hot tiles coming from the firing zone; meanwhile the lower side is in contact with the cold air. The hot surface expands due to the temperature.

This difference in temperatures and expansions are mainly responsible for the deformation of the rollers in the fast cooling zone. When searching for the best roller material for this area, it is important to analyze two main factors:

  • Thermal conductivity: to transfer the heat around and alongside the roller reducing the temperature difference between the upper and lower part. This technique ensures that the internal thermal tension of the roller (thermal load) is reduced.
  • Bending strength: A higher Module of Elasticity means that the roller can better resist the mechanical load as the tiles pass into the rapid cooling zone, they are thus less structurally and dimensionally stressed. Problems associated with transport of the tiles through the kiln are thus greatly reduced.
