With their solid construction, these high-temperature furnaces fulfill the demands of everyday work in laboratories and production. The compact standard models are suitable for melting small quantities of glass samples, for quartz glass or glass-ceramic application where high working temperatures are required and high levels of precision are needed. The very good temperature uniformity and practical details set very high quality benchmarks and are the optimum solution for many applications. The furnaces can be extended with extra features from our extensive range to suit specific processes.
- Tmax 1600 °C, 1750 °C, or 1800 °C
- Recommended maximum working temperature approx. 50 °C below Tmax of the furnace. Higher working temperatures will increase wear and tear.
- Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
- Heating from both sides via molybdenum disilicide heating elements
- High-quality fiber insulation backed by special insulation
- Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
- Long-life roof insulation with special suspension
- Temperature uniformity at 1450 °C up to +/− 6 °C according to DIN 17052-1
- Chain-guided parallel swivel door for precise opening and closing of the door
- Two-door design (front/back) for high-temperature furnaces from HT 276/..
- Labyrinth sealing ensures the least possible temperature loss in the door area
- Reinforced floor as protection for bottom insulation as standard from models HT 16/16 upwards (distributed load 5 kg/dm2)
- Vapor vent in the furnace roof with motorized exhaust air flap, controlled via the extra function of the controller
- Stainless steel exhaust hood as interface to customer’s exhaust system
- Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
- Defined application within the constraints of the operating instructions
- Controller with touch operation P570 (50 programs with each 40 segments)
