A very important recent discovery are high-performance boilers with very good efficiency that cannot be operated in the absence of ceramic filling – porous balls, made of alumina ceramics.

The heat carrier Oxal TE – 14 has no competitor in this field. These balls are made in a diameter of 14 mm, but can be manufactured with diameters up to 23 mm.

Technical specifications:

  • Content of Al2O3 – min. 95%
  • Porosity (absorption power) – min. 10%
  • Heat resistance – min. 1600°C
  • Resistance to temperature variation – the product withstands cyclic temperature changes at high temperature
