Bitwater (Shenzhen) Technology Co., Ltd. provides various firebrick options for energy efficient insulation, tailored to meet different industrial needs. The company offers vermiculite-based firebricks in different densities, including 400 kg/m³ low-density firebricks that are lightweight and suitable for applications where reducing structural load is important, such as in condensing gas boilers, where they can improve energy efficiency by up to 35% by minimizing heat loss. For heavy-duty industrial furnaces and aluminium electrolytic cells that require higher thermal resistance and durability, 500 kg/m³ high-density firebricks are available, which form a robust thermal barrier to withstand extreme temperatures and harsh chemical environments while reducing heat loss by up to 70%. These firebricks are engineered to have low thermal conductivity, high-temperature resistance, and resistance to thermal shock and chemical corrosion, ensuring both energy efficiency and long-term reliable performance in various industrial applications.
