Product Description: The DNR series box furnaces are widely used in fields such as ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, and building materials.
Structure Features: 1. The electric furnace shell is constructed with a double-layer forced air cooling design, keeping the external shell temperature close to room temperature even at high temperatures, with the shell not exceeding 50°C. 2. The furnace chamber is made of lightweight alumina ceramic fiber, offering excellent insulation properties, lightweight, high-temperature resistance, and resistance to thermal shock, cracking, crystallization, and slagging, ensuring no contamination of the products being fired. 3. Energy-saving efficiency is 60-80% of that of the old-style electric furnace. 4. Temperature control is achieved with a Yudi temperature control instrument, featuring 30-50 programmable PID self-tuning, automatic heating and cooling, and no need for constant monitoring. 5. Optional RS485 communication interface is available [connect to a standard computer to start, stop, pause heating, set heating curves, store heating curves, and record historical curves].
