Electric furnace HFL series

chamberfor aeronautics

High-temperature furnaces HFL 16/16 - HFL 160/17 have a sturdy cladding made from refractory insulation. This design offers better protection if the process produces aggressive gases or acids, such as when glass is melted. Standard Equipment Like high-temperature furnaces HT (see page 58), except: · Tmax 1600 °C or 1700 °C · Robust refractory brick insulation and special backing insulation · Furnace floor made of lightweight refractory bricks accommodates higher charge weights Additional Equipment · Cooling system to cool the furnace with a defined temperature gradient or with a preset fresh air volume. Both operating modes can be switched on and off for different segments by means of the extra function of the controller. · Thermocouple inlet with screw cap · Protective gas connection to purge with non-flammable protective or reaction gases (not completely gas-tight) · Automatic gas supply system with solenoid valve and rotameter, controlled by the extra function of the controller · Lift door · Automatic door lock incl. door contact switch · Heating elements protected against mechanical damage · Ethernet interface
