High-Temperature Furnaces with Molybdenum Disilicide Heating Elements and Refractory Brick Insulation up to 1700 °C
The Nabertherm HFL Series is a “Made in Germany” high-temperature furnace (up to 1700 °C) with **robust refractory brick insulation**. This design is ideal for harsh processes with aggressive gases, like glass melting. Features **MoSi₂ heating**, a reinforced floor, and a P570 controller as standard.
The Nabertherm HFL Series is the professional “Made in Germany” choice for high-temperature processes that require extreme durability. In fact, these furnaces are built with a sturdy cladding and **robust refractory brick insulation** with special backing. This design offers superior protection when your process produces aggressive gases or acids, such as during glass melting.
Based on the proven HT series, the HFL models feature powerful **Molybdenum Disilicide (MoSi₂) heating elements** and a reinforced floor of lightweight refractory bricks to accommodate higher charge weights. Consequently, this furnace combines the high-temperature performance of MoSi₂ heating with the resilience of brick insulation.
Standard Equipment:
Every HFL series furnace includes these premium “Made in Germany” features:
- Max Temperature: Available in 1600 °C or 1700 °C versions.
- MoSi₂ Heating Elements: High-performance heating from two sides.
- Robust Brick Insulation: Multi-layer, durable refractory brick insulation with special backing.
- Reinforced Floor: Furnace floor made of lightweight refractory bricks to support higher charge weights.
- Parallel Swivel Door: A chain-guided, parallel swinging door opens downwards, so the hot face is always away from the operator.
- Labyrinth Door Seal: Ensures the least possible temperature loss in the door area.
- Durable Housing: Dual-shell ventilated housing made of textured stainless steel for low surface temperatures.
- Advanced Controller: Comes standard with the powerful **P570 controller** (50 programs, 40 segments each).
