The ICRACONCEPT® refractory supports are distinguished by their light structure with a high moment of resistance and a much lower incidence of weight/m2 than traditional supports. In particular, the entire range of hollow-core setter slabs, thanks to their intrinsic qualities, permittes:
• Faster firing cycles and energy savings;
• Reduction in problems of thermal shock and cracking.
ICRA can satisfy every customer’s need thanks to its ability to produce setter slabs with widths of up to 625 mm and lengths of up to 2000 mm, and the possibility of creating various unique finishes. The products are made based on the CONCEPT C, CONCEPT C2 and CONCEPT C3 formulas, which are distinguished by their low coefficients of thermal expansion.

The new T11 Eco Light batt for sanitaryware firing
T11 Eco Light, presented for the first time in September 2024 at TECNA exhibition in Rimini, it’s the thinnest and lightest cordierite batt ever produced.
Wall thickness: solo 4 mm
Weight: 29 kg/m²

RISPARMIO ENERGETICO
T11EL ENERGY SAVINGS CALCULATION
Car dimension2,5 m x 3,00 m = 7,5 m²
Weight of T11UL35,2 kg/m² x 7,5 m² = 264,00 kg/ca
Weight of T11EL28,1 kg/m² x 7,5 m² = 210,75 kg/car
Supposing that:
- Cordierite specific heat
0,2 Kcal/°K/kg - Heat necessary to heat 1 Kg of cordierite up to 1200 °C
244 Kcal/kg - Natural gas specific heat
8200 Kcal/m³ - Nr. of cars entering the kiln per day
42 cars - Working days per year
365 days
Consumption to heat a car with T11UL slabs:
264,00 x 244 / 8200 = 7,855 m³ of natural gas
264,00 x 244 / 8200 = 7,855 m³ of natural gas
Consumption to heat a car with T11EL slabs:
210,75 x 244 / 8200 = 6,271 m³ di natural gas
Energy savings:
(7,855 – 6,271) m³ x 42 x 365 = 24.282 m³ of natural gas/ year
The exclusive ICRACONCEPT® brand is a guarantee of the technological specifications of our products.

ICRA Concept's formulations
Concept C
This type of formula is particularly suitable for firing sanitary ware in roller kilns, thanks to its excellent resistance to thermal shock.
Concept C2
This is ICRA’s most used refractory formula. C2 products are used by a great number of sanitary fittings manufacturers throughout the world. They offer countless advantages, including the lightness and resistance of the material.
Concept C3
This is the formula recommended for the most critical situations. Its main feature is that it offers greater refractoriness, thereby enabling large loads to be fired without having to increase the size of the refractory support. It is also suitable for manufacturing the columns required for the complex superstructures of kiln cars.
